How to remove humidity in an apartment: useful tips

For full life, a person needs air with an optimal level of humidity. It is not uncommon for this level to rise in the bathroom, kitchen, living room or vestibule.

Table of contents:

The owners are clutching their heads, not knowing how to get rid of the smell of dampness and high humidity that has appeared. In addition to the fact that an unpleasant aroma permeates clothes and wooden decorative elements, mold appears on the walls, which spoils the entire impression. To cope with the problem in a short time, you need to follow practical recommendations.

Optimal humidity level

It is generally accepted that a living space should have a humidity level that ranges from 50-60%, not higher. To measure the microclimate, you need to use a device called a hygrometer. In the summer, it is possible to reduce the humidity level to 35-40%, this feature is achieved for obvious reasons.

It is known that the human body tolerates both excessively humid and dry climates equally poorly. People who use split systems should be extremely careful. The air conditioner sucks in moisture, causing the optimum reading to drop. However, if you often dry clothes in a living room and not on the balcony, the split system will become a lifesaver.

Causes of high humidity

  1. High humidity occurs for many reasons, one of which is considered to be the lack of both natural and artificial ventilation. If there is air circulation, then it’s worth checking how well it works.

Consequences of high humidity

Important attention must be paid to health, which deteriorates due to high humidity.

  1. In such conditions, the human body is unable to cope with even the most banal cold syndromes, what can we say about serious diseases. If you are constantly and for a long time in a humid environment, a common cold can develop into something more.
  2. In addition to weakening the immune system, a humid microclimate causes allergies, eczema, skin rashes, insomnia, runny nose, muscle and joint pain. Also, high humidity contributes to the development of apathy, general fatigue, and depression.
  3. There are often cases when the emerging fungus becomes the cause of the development of chronic diseases. Older people and children are most susceptible to such reactions. In the first category, the protective functions of the body do not work fully; in the second category, the body is not yet fully formed.
  4. If air humidity exceeds optimal limits, a pungent and unpleasant smell of mold develops in the apartment. The stench penetrates into furniture upholstery, soft floor coverings, clothes, towels, bed linen, mattresses and pillows.
  5. Due to increased humidity, the seams in the room turn black, indicating the development of mold. With each passing day, the fungus affects an increasingly larger surface, threatening walls, ceilings, cabinets, window frames, etc.
  6. If high humidity persists for a long time, accelerated spoilage of food products (baked goods, vegetables, fruits, flour, cereals and legumes) begins.

How to remove humidity in an apartment

  1. Air Dryer. The best option for dealing with high humidity is considered to be the use of a dehumidifier. The pricing policy depends on the specific manufacturer, the power of the unit and its model. You can purchase the device in “Everything for the Home” stores, as well as in electronics hypermarkets. It is worth clarifying that the more productive the unit, the faster it will cope with high humidity. If possible, purchase a device with a regulator and a table that displays the dampness level. This feature will allow you to save on electricity and not dry out the air.
  2. Heating radiators. You can get rid of excessive moisture in the room using heating radiators. Batteries are present in every apartment, but they cannot always be used (with the exception of the summer-spring period). If you notice that dampness persists for a long time, periodically heat the room. During a kind of heat treatment, the fungus dies and the air becomes much drier. Turn on the heating only in the cold season, avoid sudden changes in temperature, which cause windows to sweat.
  3. Fresh air. It is known that a humid environment is afraid of fresh air, but only if the ventilation does not occur in cloudy and rainy weather. Make it a habit to open the windows 3 times a day, leave them for a quarter of an hour, as long as possible. If possible, keep the window open constantly, closing it only in case of precipitation outside. To make ventilation much more efficient, install plastic windows that open upward (micro-ventilation). Such a move will eliminate the possibility of drafts and remove humidity.
  4. Sugar and salt. The listed products absorb moisture well, but, as a rule, they are used extremely rarely. Agree, it’s not very convenient to hold a five-kilogram bag with a loose composition in the middle of the room, even in an open state. This option is useful in the fight against humidity in small rooms, such as a pantry, vestibule, and bathroom. It is enough to pour salt or sugar into a basin, then take it indoors, do not forget to stir periodically.

Preventive actions

  1. Inspect sewer pipes and heating radiators to find out if there is a leak. If this happens, call a technician or fix the problem yourself.
  2. If it is sunny and warm outside, ventilate the room constantly. Do not sit in an apartment with the windows closed for a long time.

It is quite difficult to get rid of high humidity in an apartment if you do not have knowledge regarding the available methods. Ventilate the room more often, install an air conditioner, and heat the apartment. Buy a dehumidifier and run it at least 4 times a week.

What air humidity is considered normal in an apartment - the importance of the parameter and its standards

When assessing the air parameters in a home, most people first of all pay attention to its temperature, forgetting about such an important indicator as humidity. The subjective sensation of heat or cold, general well-being, the condition of plants and the safety of many household items depend on it. Let's figure out what the norm of air humidity in the apartment is, and also find out what it affects.

Problems arising from lack/excess moisture

The humidity indicator reflects the degree of saturation of the air with water vapor. It can be absolute and relative. In the first case, it is determined how many grams of moisture are contained in 1 cubic meter of air. In the second, the percentage ratio of the actual amount of water in the atmosphere (absolute indicator) and the maximum possible at a given temperature is calculated.

When using such a concept as the norm of humidity in an apartment, a relative indicator is implied. This parameter largely determines the comfort of the indoor microclimate. Both the person and the home environment suffer from too much or too little humidity.

Dry indoor air provokes increased moisture loss through the skin and respiratory tract. This can lead to such unpleasant consequences as:

  • decreased elasticity of hair, nails and skin, accompanied by the appearance of microcracks, wrinkles, peeling, dermatitis;
  • drying of the mucous membrane of the eyes, the symptoms of which are itching, redness, and a feeling of “sand”;
  • thickening of the blood, leading to a slowdown in blood circulation, weakness, headaches, decreased performance, and increased stress on the heart;
  • an increase in the viscosity of gastric and intestinal juices, causing a slowdown in digestion;
  • drying out of the mucous membranes of the respiratory tract, which results in a weakening of local immunity and an increase in the frequency of acute respiratory viral infections;
  • an increase in the amount of respiratory allergens in the atmosphere, which should normally be bound by liquid droplets.

Excess moisture in the air creates acceptable conditions for the growth of mold, fungi, and bacteria. As a result, residents of the house may encounter:

  • respiratory diseases - chronic runny nose, bronchitis, asthma, allergies;
  • feeling of stuffiness or dampness in the room;
  • unpleasant odor due to the proliferation of pathogenic microorganisms;
  • increasing the drying time of washed laundry.

Excessive or insufficient amount of moisture has a bad effect on the condition of home furnishings. Plants dry out or begin to rot, wooden furniture and parquet floors become deformed or “shrink,” paintings fade, paper products lose their structure.

Factors affecting humidity

The main factor that affects air humidity is its temperature. The warmer it is, the greater the amount of water vapor it can maximum accommodate, and vice versa. But when assessing relative humidity, an inverse relationship applies: the warmer the air, the lower its relative humidity will be for the same volume of water vapor contained in it. Therefore, airing in winter makes the air fresher, but less humid. The optimal temperature is ºC.

Water vapor is “taken” from the air in the room:

  • any heating devices;
  • air conditioner;
  • interior items, especially upholstered furniture, toys, carpets.

Any sources of water and steam lead to an increase in relative humidity:

  • aquarium;
  • houseplants;
  • wet laundry;
  • containers with boiling water (saucepan, kettle);
  • leaking roof;
  • faulty water pipes and plumbing.

Constant condensation on the windows indicates an increased level of humidity in the apartment

Standard indicators

Let's figure out what air humidity is considered normal in an apartment. It depends on the purpose of the premises and the time of year.

Humidity standards for housing:

  • warm period - 30-60%, maximum allowable - 65% (for certain regions with high humidity, this standard can be increased to 75%);
  • cold period - 30-45%, maximum permissible - 60%.

Relative air humidity is not standardized in auxiliary rooms - bathroom, toilet, corridor, pantry and others.

Standards for plants and interior items:

  • for furniture and antiques – 40-60%;
  • for equipment – ​​45-60%
  • for books – 30-65%;
  • for plants – tropical – 80-95%, subtropical – 75-80%, others – 40-70%.

What is the normal level of relative humidity in the apartment where the child lives? Since the intensity of heat exchange processes is increased in young children, they are especially sensitive to non-compliance with microclimate parameters. The ideal air humidity in a children's room is 50-70%. If a child is sick with ARVI or an infectious pathology, then this parameter should not be allowed to decrease below 60%.

To maintain optimal humidity levels, it is often recommended to install humidifiers in children's rooms.

Important: During the heating season, air humidity drops to 15-20%. It definitely needs to be raised, especially if there are children, asthmatics and allergy sufferers in the house.

How to measure relative humidity?

Knowing what the optimal air humidity in an apartment should be, it is worth deciding how it can be measured. The most rational way is to use a special device - a hygrometer.

There are several types of devices - electrical, chemical, condensation, hair and others. There is no need to purchase an expensive professional device for an apartment. The simplest hygrometer with an error of 3-5% is enough. It is often combined with a clock and a thermometer. It is important to place the hygrometer away from sources of moisture and heat.

You can determine humidity using alternative methods - a glass of water, an Assmann table and a fir cone.

Glass of water

Pour water into a glass and cool it to 3-5 ºС. To do this, just put the vessel in the refrigerator for 3 hours. Next, you need to place the glass on the table away from the radiator and watch it for 5 minutes. At the same time, condensation forms on its walls due to temperature differences. Possible results:

  • the glass has dried within a few minutes – the humidity is reduced;
  • the walls remained fogged - the microclimate parameters were normal;
  • Streams of water flowed down the glass - there was too much moisture in the air.

Assmann table

The Assmann table is designed to determine humidity using a psychrometer - an instrument consisting of two thermometers - a regular one and one with a humidification device. Its likeness can be made at home. You must first measure the temperature in the room with a regular alcohol thermometer and write down its value. Then you should wrap its end with a damp cloth. After 5 minutes, the temperature must be measured again. It should go down.

Next you need to look at the Assmann table. The readings of the “dry” thermometer are located vertically, and the temperature difference is located horizontally. Having seen the desired values, you should find their intersection. This will be an indicator of relative humidity.

fir cone

You need to place a fir cone in the room away from heaters. Within a few hours, its scales can either open (in dry air) or shrink even more tightly (in high humidity).

Note: Indirect signs of low indoor air humidity are drying out the tips of plant leaves and electrical discharges emanating from synthetic clothing.

Humidity regulation

At any time of the year, normal air humidity in the apartment should be no less than 30-40% and no higher than 65%. How to regulate it?

Ways to reduce humidity:

  • frequent ventilation of premises;
  • installation of exhaust fans;
  • use of dehumidifiers and climate control systems;
  • timely repair of water pipes and plumbing fixtures;
  • use of heaters and air conditioners;
  • refusal to dry clothes in the room;
  • installation of a hood in the kitchen.

Methods for increasing humidity:

  • purchasing an aquarium or decorative fountain;
  • minimal use of heater and air conditioner;
  • hanging wet towels on radiators;
  • periodically spraying water from a spray bottle;
  • using an air humidifier - steam, ultrasonic or traditional;
  • regular wet cleaning;
  • growing a large number of indoor flowers.

Air humidity in a house is an important parameter that affects both the well-being of its inhabitants and interior items. Normally, this figure ranges from 40 to 60%. It is especially important to monitor the humidity in rooms where children and people with respiratory diseases spend most of their time. To regulate the moisture concentration in the air, it is convenient to use household humidifiers and dehumidifiers.

The situation looks most critical during the heating season. Frosty air contains little moisture, so ventilation alone cannot achieve optimal air humidity in the apartment.

Ventilation in winter does not moisturize, but rather dries the air.

It depends on the humidity in the apartment. We have %, so ventilation in winter, even in frosty sunny weather, increases humidity.

Ventilation in winter definitely dries out the air!

In a cube of frosty air, even at 99% humidity, the amount of water in grams is several times less than in a cube of air at room temperature at 17-18% humidity!

After ventilation, the frosty air warms up to room temperature, and the amount of moisture in grams remains the same. As a result, the relative humidity drops even less than your 18%.

An option is not to close the windows at all in winter, then the moisture levels in the apartment will be the same as outside. Provided that the air temperature is the same as outside. 🙂

The apartment has low humidity

The point is that we are talking about relative humidity. This means that 100% is taken to be the amount of moisture that at a given temperature can be in the air and not condense into water droplets. So this ability of air to retain moisture very much depends on temperature. At subzero temperatures, the air can hold very little moisture. So air with 100% humidity at -20 degrees, when heated to +20 degrees, will have a humidity of only 6%. This is approximately the humidity we will have at home if it is -20 degrees outside.

Does relative humidity matter, or is it just a numbers game? Really important. At 100% relative humidity, water does not evaporate. And when air humidity is low, water evaporates quickly. Therefore, at low humidity, plants and potentially our skin, including the nasopharynx, dry faster. It is argued that a dry throat is less resistant to infection, which increases the likelihood of getting a “cold throat” in winter, while being in a heated room.

The solution to the problem may be an air humidifier, or a pan of boiling water on the stove (but it will only humidify the kitchen), or abundantly hung wet things (but just in winter they will dry out in a few hours and stop humidifying the air). But abundant watering of flowers and placing basins of water increase air humidity very little.

What is the optimal air humidity in an apartment?

It's no secret that each apartment has a special microclimate. This concept includes temperature conditions, lighting, humidity and many other parameters. All of them have a direct impact on people's quality of life. If any indicators are too high or, conversely, low, both your own health and the decoration of the apartment may suffer. Therefore, you definitely need to monitor your home and prevent such situations. Let's find out how the level of humidity in an apartment affects our lives and why it is so important that it is within normal limits.

How does high and low humidity affect humans?

Both high and low humidity have a direct impact on the life and health of the apartment’s inhabitants.

High humidity

Let's consider a situation where the humidity in the apartment is high.

  • If the air is too humid, the body perceives temperature differently. The process of heat transfer is disrupted; at high temperatures the body overheats, at low temperatures it becomes hypothermic.
  • This phenomenon, combined with high indoor temperatures, is especially dangerous for people suffering from hypertension and cardiovascular diseases: it leads to dehydration and chemical imbalance, blood thickening, high blood pressure and exacerbation of chronic heart and vascular diseases.
  • High humidity negatively affects the physical and mental activity of even a completely healthy person, since fatigue sets in much faster in such conditions.
  • If a person is in a room or apartment with high humidity, he is more susceptible to infectious diseases and colds. A long stay in such conditions can contribute to the development of more serious diseases: rheumatism, tuberculosis, etc.
  • High moisture content in the air is dangerous for allergy sufferers. The environment in damp rooms is very favorable for the appearance of mold and fungi - powerful allergens that can lead to truly adverse consequences for the body, not to mention the fact that they spoil the appearance and decoration of the apartment.

In addition to fungus and mold, high humidity promotes the development of various pathogenic microorganisms and insects. It spoils furniture and creates an unpleasant musty smell.

Low humidity in an apartment has the following consequences:

  • Too dry air dehydrates the body and dries out the mucous membranes. Dry nasal mucosa is the cause of frequent colds.
  • The skin becomes dry, inelastic, and metabolism is disrupted.
  • People experience constant nasal congestion and difficulty breathing, which lead to sleep disturbances, anxiety and irritability.
  • Dry air in an apartment contributes to the spread of dust, in which various microorganisms, as well as dust mites, can multiply.
  • The leaves of indoor plants dry out and fall off.
  • Wooden furniture and parquet dry out and become cracked. The same applies to musical instruments made of wood: they are constantly out of tune and gradually become unusable.

What air humidity is considered optimal?

Both excess and lack of moisture in the air pose a danger to the health and condition of the apartment. What should the ideal humidity be in a living space?

  • In order for a person to be comfortable in a room, the air humidity should be from 30 to 60%.
  • Comfortable air humidity in an apartment during the cold period is about 30–45%.

In the warm season, maintaining this level is not at all difficult. However, in winter, with batteries and other heating devices running, this can be very difficult. At this time of year, the percentage of water in the air sometimes drops to 20%, and sometimes even to 15%, which is completely unacceptable.

Normal air humidity in an apartment is of great importance not only for people, but also for various objects. For example, for indoor flowers, furniture and books, the optimal figure is 40–60%, for household appliances – 45–60%.

How to measure the humidity level in an apartment?

There are several ways to help determine the humidity level in a room.

Hygrometer

A hygrometer is a special device with which you can easily determine the exact percentage of air humidity. There are devices called weather stations, which, in addition to a hygrometer, include a thermometer, barometer, clock, calendar and other useful additions. The device can be kept in the room constantly to monitor changes in humidity.

Glass of water

This is a less reliable method, but is often used at home. If you don’t want to purchase a special device, you can measure the air humidity level using a container of water.

Pour water into a glass and place it in the refrigerator for several hours. During this time, the water temperature should drop to 3–5 °C. Then place the glass indoors away from heating appliances. At first the walls of the container will be foggy, but you need to observe what happens to them after 5 minutes.

  • If they dry out, it means the air in the room is dry.
  • If the glass remains fogged up, the humidity in the room is at the optimal level.
  • Streams flowing down the walls of the glass will help you find out about high humidity in the room.

This method does not require special equipment, but it will not allow you to find out the exact value of water content in the air.

What to do if the humidity is too high?

So, we have learned to determine the degree of indoor air humidity. Let's say you get a result indicating that your room is too high. What will help in this case?
  • Air Dryer. This device will allow you to get rid of humidity in your apartment in the shortest possible time. The dehumidifier can be portable or stationary.
  • Moisture absorber. It usually takes the form of a tablet made from a special absorbent substance.
  • Hood. Unventilated rooms where moisture constantly accumulates are best equipped with exhaust devices: a ventilation duct, a recuperator. If the hood in the apartment is not functioning well, it is recommended to install a forced ventilation system.
  • Air conditioner. It will help eliminate excess moisture and maintain its optimal level in the room.
  • Frequent ventilation. The flow of fresh air also helps reduce the water content in the air.

How to increase humidity if the apartment is too dry?

If the air in your apartment is too dry, the situation can be corrected in the following ways.

Humidifier

The easiest way to increase humidity is to install a humidifier in your room. This device is capable of affecting the air in rooms up to 150 square meters. m. The principle of its operation is simple - you need to pour water into a container specially designed for this purpose, which the device will evaporate, saturating dry air with water vapor. There are three types of humidifiers:

  • Traditional (cold type). They have a simple design with humidifying cartridges and a fan that drives air through them. Such a device can restore normal air humidity (up to 60%), its disadvantages include noise.
  • Steam. They operate on the principle of an electric kettle: they boil water and release it outside in the form of steam. Advantages: high performance, lack of consumables, ability to work with ordinary tap water. Disadvantages: quite high noise level and power, steam that can burn you (up to 60 degrees).
  • Ultrasonic. Considered the most modern, their work is based on the vibration of a membrane that turns water into cold steam. They operate almost silently and allow you to regulate the humidity level. Some models heat the water, killing germs and bacteria. The disadvantage is that it requires maintenance, the use of cartridges that regularly need replacement, or distilled water.

Water containers

This method has been used for many years. One or more containers with water are placed on the batteries. The water gradually evaporates, humidifying the dry air.

Installation of an aquarium or decorative fountain

Such items help to humidify the air a little, but will not radically solve the problem.

Breeding indoor plants

This will also help increase the moisture content in the air as plants give up moisture and also require constant watering.

By maintaining a comfortable level of humidity in your apartment, you can not only help your body and maintain health, but also extend the life of many things.

The norm of air humidity in the apartment, maintaining optimal conditions using different technologies

To ensure comfortable conditions, it is necessary to clarify what the norm of air humidity in the apartment is. With the help of today's publication, you can quickly study theory and practice on a given topic. The knowledge gained will be useful for solving practical issues at reasonable costs.

In today's article:

Air humidity - what is it?

To eliminate errors and better understand individual important processes, it is necessary to clarify the basic definitions. Air can contain a limited amount of moisture. When conducting an experiment with maintaining static pressure and decreasing temperature, condensation forms.

Absolute humidity is called humidity, which is determined by the formula:

Taking into account the above information about the influence of temperature, the relative indicator is more informative. To calculate it, take the absolute humidity value and divide it by the maximum permissible water content in the atmosphere corresponding to certain conditions. The result obtained is multiplied by 100. This is relative humidity. This is what is indicated in the standards and measured using specialized instruments.

The relationship between the parameters is shown in the following table:

Factors influencing the recommended air humidity in the apartment

Before finding out what air humidity in an apartment is considered normal, you need to understand the mechanism for changing this parameter. From general information, we can conclude that there is a significant decrease in moisture concentration in winter when the temperature drops below zero. Consequently, normal ventilation of premises will have a negative impact on the corresponding standard.

Separately, we need to consider the persistent myth about air “overdried” by heating devices. This technique is actually capable of converting water into steam particles. However, it will not leave the room if there is no effective exhaust ventilation.

What actually reduces humidity levels is equipment that is designed to lower temperatures. Moisture concentrates on the cooled plates of the air conditioner heat exchanger. The drops roll into a special tray and are removed through a special tube into the drain.

However, the use of a “Russian bath” or “hamam” involves a high concentration of water in the room atmosphere. Humidity increases:

  • in showers and bathrooms;
  • in the kitchen during cooking;
  • during operation of steam generators and air humidifiers.

Optimal air humidity in an apartment - GOST requirements

To obtain detailed information and clarifications, use the original source. In this case, we are talking about GOST (2012) “Indoor microclimate parameters”, which came into force on January 1, 2013 (the latest amendments were made in 2016).

This standard is developed for residential, public, and educational real estate. It defines the limits of humidity, temperature and air mobility, which, with prolonged exposure to the human body, are not capable of causing harm to health. Acceptable indicators are regulated taking into account the possibility of certain discomfort caused by individual physiological characteristics.

The concept of “optimal” parameters is also used. They mean a combination of the above factors that does not activate the natural functions of thermoregulation. At the same time, comfortable conditions are provided for people in the room with a statistical sample of at least 80% using a special research methodology.

A person’s stay in a room for at least 2 consecutive hours or 6 hours cumulative over a whole day is considered permanent. Cold is the period of the year when the temperature is equal to or below +8°C (24-hour average). The rooms are classified in detail into 6 categories, taking into account the type of activity and clothing. Below are the standards for residential properties.

What air humidity should be in the apartment in summer?

For the warm season, the standards are increased. When the weather is good, users often ventilate the room. The air parameters outside are quite favorable, so it is not difficult to meet the requirements of the standards.

The use of technical means for adjusting microclimate parameters is discussed in detail below. However, it can be noted that such equipment can be used in rainy weather to reduce humidity levels.

What should be the humidity in an apartment in winter?

During this period, reduced standards are used. It should be remembered that it is necessary to comprehensively take into account all significant factors to create comfortable and healthy conditions.

In winter, you will have to solve the problem of sufficient ventilation while maintaining normal humidity levels.

What humidity should be in a child's room?

At the stage of formation of the organism, individual physiological mechanisms are unable to perform their functions fully. In particular, thermoregulation is difficult.

For this reason, caring parents overly insulate the baby and thereby make a mistake.

Humidifier: ranking of the best of the year. In this publication we will consider the criteria for choosing humidifiers, manufacturers and the best models, optimal prices and recommendations from specialists.

The growth of the body is accompanied by active production of heat. Its removal is carried out along with exhaled air and through the skin. The second way is accompanied by the release of sweat, loss of valuable moisture and beneficial salt components. Lack of fluid makes digestion difficult. Drying of the mucous membranes occurs. The appearance and condition of the skin deteriorates.

Taking into account the above facts, experienced pediatricians recommend maintaining a temperature range in the children's room from +18°C to +20°C. The value of +22°C is considered a threshold value and should not be exceeded. At the same time, sufficient fluid intake should be ensured along with food and drink. It is necessary to take a bath regularly and maintain the optimal air humidity in the room for the baby at 50-60%. For the prevention and treatment of respiratory diseases, experts recommend maintaining a level of 60−70%

How to measure air humidity in an apartment

Hygrometer - a device for measuring indoor air humidity

This figure explains what a hygrometer measures and how. Ether or other easily evaporating liquid (2) is poured into a small container. Using a conventional “pear” (4), air is pumped through it, which is accompanied by gradual cooling of the metal case. At a certain moment, condensation forms on the outer polished surface (1). This temperature is recorded using the built-in thermometer (3). Next, using the dew point value in the table, find the corresponding relative humidity value.

Devices in this category are more convenient, since with precise adjustment you can immediately see the result on the scale. In this case, they take advantage of the property of the reference material to change size when the level of air humidity in the apartment increases/decreases.

If you pump humidified air through a hygroscopic sample, the measured parameter can be determined by the change in weight. But this and the methods listed above do not correspond to the habits of modern users.

An electronic device for determining air humidity is convenient, informative, and has other advantages.

This technique performs its functions using different principles:

  1. By supplementing the condensation hygrometer with a light emitter and a photocell, an automated installation for fixing the dew point is created.
  2. When the humidity level in the apartment fluctuates, the resistance of the electrolyte or porous sensor will change accordingly.
  3. Using appropriate electronic circuits, the capacitance of capacitors is measured (some metal oxide and polymer models are suitable).

The resulting value is corrected taking into account the readings of the built-in sensor and temperature. The final results are displayed on the screen. A well-equipped electronic hygrometer has the following advantages:

  1. The large LCD screen does not consume much electricity.
  2. To improve visibility, install backlighting.
  3. In addition to the relative air humidity in the apartment, temperature, time, calendar, and other useful information are displayed.
  4. It is possible to add external sensors to monitor parameters in several rooms and outside the building.
  5. The received data is transmitted over the Internet and used to control household appliances.

Determination of humidity level using the Assmann psychrometric table

This technology can be reproduced using simple measuring instruments at home. Take two alcohol thermometers and attach them to a single panel for convenience. The tip of one is dipped into a ball of cloth, which is moistened with clean water. Using this table, the obtained readings are converted into the operational value of air humidity in the apartment.

Main components of the device, factory psychrometer

Despite the emergence of modern electronic models, such devices are in demand. They are cheap and perform their functions without batteries. Despite the apparent primitiveness, fairly high measurement accuracy is ensured. In some manufactured products, the scale division value is no more than 0.2°C.

For an objective analysis, the following limitations and features should be mentioned:

  1. Alcohol-containing liquid is harmless, but even a slight blow can damage the fragile glass parts of the structure.
  2. A standard room air humidity meter of this type is designed for operation in the operating range from -10°C to +40°C.
  3. If the measurement is performed at a temperature less than +23°C, the air humidity in the apartment is determined only from a level of 40% or more.
  4. A strong draft (flow speed greater than 1 m/s) significantly impairs accuracy.

“Glass of water” and other simple techniques

How air humidity is measured is clear from the previous sections. However, the correct conclusions can be drawn based on indirect evidence or using available means.

Plants dry out due to lack of moisture

Dry skin also indicates the need to correct microclimatic parameters.

Excess moisture, on the contrary, can lead to mold and mildew.

For a quick check, fill the glass halfway with tap water and place it in the refrigerator compartment (standard temperature from +4 to +6°C). After 1-1.5 hours, the measuring device is removed and installed on any flat surface away from heating system devices and other heat sources. Avoid direct exposure to sunlight. If after 6-8 minutes there are drops of water left on the walls, it means that the air humidity in the apartment is normal. Drying of condensate/drops flowing down corresponds to a decreased/increased level, respectively.

You can also use a standard alcohol thermometer. Measure the temperature as usual. Next, immerse the device in cotton wool or other porous material moistened with water. Using the obtained data and Assmann's psychrometric table, obtain the air humidity value in the apartment.

What are the consequences of deviations from the norm of air humidity in an apartment?

The normal humidity in the apartment should be such that a person feels comfortable. The above figures are based on official studies. However, we must not forget that they are average indicators. In order not to make mistakes, it is necessary to take into account individual characteristics. People suffering from asthmatic attacks may experience discomfort with high and low levels of air humidity in the apartment.

Lack of water impairs immunity and the effectiveness of the body's defense systems. The nutrition of hair roots, integumentary and other tissues is disrupted. Cosmetic defects appear. Drying of the mucous membranes is accompanied by pain in the eyes. Blood oxygen saturation decreases.

Excessive humidity creates a favorable environment for the life of mites and various harmful microorganisms. Some of them provoke the occurrence of extremely dangerous and chronic diseases. If the standards are not followed, children and older people are at particular risk.

Valuable antique furniture will not be damaged if you maintain air humidity in the apartment from 40 to 60%

Approximately the same range is provided by developers of household appliances. A high concentration of water in the atmosphere of a room intensifies corrosion processes that destroy durable metals. Under such conditions, oxides are formed that disrupt the normal conductivity of electrical circuits. It is difficult to localize the corresponding faults. They are the ones who quite often damage high-quality smartphones, TVs, and other equipment.

For tropical plants, the air humidity level must be increased

This example once again confirms the correctness of the individual approach. To maintain a special microclimate, individual rooms must be well isolated from other parts of the property.

Ways to normalize moisture

The sum total of all the important facts explains the benefits of preventive measures. Maintaining an optimal level of air humidity in the apartment helps save money, prevents accidents and illnesses. All that remains is to figure out how to solve the problem correctly. To do this, we will consider successively specialized equipment and technologies that are used in practice.

How to increase the humidity in an apartment using modern technology

This technique creates tiny water droplets using high-frequency vibrations of the working element. To the listed advantages we can add compactness, reasonable cost, and attractive appearance of modern models.

Sets of disks are installed in such devices. When rotating, these blocks are wetted with water at the bottom. Affordable prices distinguish products in this category.

Multifunctional humidifiers are equipped with a built-in hygrometer. Such devices maintain the user-specified humidity level in the apartment, taking into account real conditions. Additional equipment:

  • flavoring;
  • ionizer;
  • filter for retaining hardness salts;
  • rotary device for changing the direction of release of water vapor;
  • filters for cleaning incoming air from dust, odors, and other impurities;
  • remote control.

How to increase the humidity in a room using improvised means

A similar result can be obtained using a hand sprayer and frequent wet cleaning.

To increase the level of air humidity in the apartment, use dampened towels, various homemade products with liquid dispensers, and factory-made specialized products for installation on a heating radiator.

Ways to reduce air humidity in an apartment to normal

In swimming pools and to solve industrial-scale problems, specialized moisture absorbers are used.

In residential buildings, the same functions are performed by a conventional air conditioner when the “Cooling” mode is turned on. Absorbent-type moisture absorbers are also used

It is easy to make such a design yourself. A special tablet is placed on the top shelf. It absorbs moisture from the air and converts it into a saline solution. To accumulate it, a corresponding reservoir is installed below. It is emptied manually.

Absorbents are produced in the form of tablets and granules, with and without aromatic fillers

Conclusions and useful tips

Causes of dampness in the apartment and ways to get rid of it

Living in an apartment with high humidity is uncomfortable and sometimes dangerous. In such rooms, fungus appears on the walls, causing allergic reactions. Such a microclimate leads to health problems. In humid air, joints begin to ache, constant colds torment, insomnia begins, chronic nasal congestion, general weakness and other unpleasant symptoms appear.

Optimal humidity in a living room%. In winter, when central heating batteries are running, the air in the apartment becomes drier. Both excessively high water vapor content and excessive dryness are equally dangerous for human health.

Most often, drying clothes on radiators and poor ventilation lead to an increase in humidity in the apartment.

If the air is often damp, sooner or later dampness will appear, from which interior items will suffer, furniture and leather upholstery will deteriorate, plaster will crumble, wallpaper will peel off, and the wooden floor will deform. In a damp apartment, books and documents spoil, and food quickly becomes moldy. But the worst consequence of dampness is mold and mildew that appear in the corners of the apartment. These microorganisms can ruin your health and quickly render your home unusable, especially if the walls are made of wood.

In a damp apartment, the general condition of the body worsens. Excessively humid air is the cause of increased oily skin, greasy hair, skin rashes and allergies. People living in damp conditions are prone to pulmonary diseases, they may develop chronic bronchitis and other problems with the respiratory organs. Excessively humid air is heavy and the room smells bad, making it unpleasant to live in. In a damp atmosphere, any bacteria multiply quickly, so residents are susceptible to dangerous infectious diseases, including tuberculosis.

Dampness in a room can occur due to internal and external reasons. To determine where moisture penetrates from outside or inside, it is enough to conduct a small experiment. Glass is placed on the wall facing the street for several hours. If a closed area becomes damp, it means that dampness is entering the room from outside. This is especially common in corner apartments or in houses in the construction of which waterproofing standards were violated.

If the part of the wall covered with glass turns out to be dry after a few hours, you need to look for the reasons for the dampness inside the room. It can be:

  • on the ground floor in a house with a basement - rising groundwater or man-made flooding of the basement;
  • poor ventilation or its absence - this happens when neighbors close the ventilation shaft;
  • leaking plumbing, for example, the bathtub does not fit tightly to the wall and while taking a shower, water penetrates the floor, accumulating in puddles under the bathtub;
  • drying a large amount of laundry in the apartment, which happens when there is a small child or a bedridden patient in the family;
  • passion for house plants - any indoor flower evaporates water from its leaves and affects the microclimate in the apartment.

Sources of internal humidity on the 1st floor or any other, as well as in a private house without a basement, can be:

  • frequent showers or baths;
  • daily washing;
  • cooking food;
  • breathing and evaporation of moisture through the skin;
  • presence of aquariums in the apartment.

It is estimated that as a result of the economic activities of a family of 3 people, up to 100 liters of water are released into the air every week. It is not surprising that in apartments with sealed plastic windows and poor ventilation, the microclimate changes so much that the walls begin to become damp, and black mold appears in the corners.

To reduce humidity in an apartment, the first step is to check the operation of ventilation and the tightness of heating and water pipes. If there is something wrong with these systems, you will have to contact specialists. If the ventilation and pipes function flawlessly, you can reduce the humidity in the following ways:

  1. 1. Ventilate the room regularly - just open the windows wide for at least 10 minutes and the damp air will escape.
  2. 2. The bathroom door should be left open at night.

Residents of megacities can turn on the air conditioner instead of ventilating. This will help get rid of dampness in the apartment and prevent gas contamination.

An alpine window (supply valve) will help dry the air. The device provides fresh air into the apartment even in winter. An alpine window is necessary in a room with poor gas exchange. To install the system, you will have to make a hole in the outside wall. It is covered with heat and sound insulating material. You can regulate the level of fresh air entering the apartment using a damper. Exhaust air leaves the room through natural ventilation. Alpine vents are installed above the windows. The device is not suitable for ventilating bathrooms, kitchens and toilets - these rooms require forced ventilation.

Air conditioner effectively reduces humidity and eliminates the smell of dampness. The device has a drying function. You can simply use it as a hairdryer for indoor air by turning it on to the appropriate mode. But even during normal operation, the air conditioner slightly dries out the room.

A high-quality antiseptic will help remove fungus and mold that appeared on the ceiling and in the upper corners after another flood. Such products are sold in hardware stores.

The room, heavily damaged by fungus, needs repair. Wallpaper is removed from the walls. Sometimes you even have to remove the plaster. All surfaces are treated with an antiseptic and cleaned of fungus and mold. Severely affected areas of the walls can be coated with creosote. After applying the impregnation, the walls and ceiling must be completely dry, only then can they be finished. It is better to use wood and drywall for finishing. These materials absorb water when there is excess air humidity, and release water in a dry atmosphere.

In winter, the room becomes damp due to the cold. To reduce humidity, it is enough to use electric heating devices until the central heating is turned on. They will warm the room and dry the air. Chemical products for dehumidifying apartments are also produced. For example, the Henkel company markets the “Stop Moisture” system, which includes an absorber and an absorbent. Atmospheric moisture is absorbed by the absorber and enters a special container, from where it can simply be poured into the sewer.

Good absorbers of moisture from the air are salt, sugar and coffee. To use these folk remedies, it is not necessary to place bags of bulk products around the apartment. You can simply pour some coffee beans, salt or granulated sugar into a beautiful glass vase or wine glass. Excess moisture will quickly settle in the container.

Silica gel absorbs moisture well. Envelopes with the product are laid out in closets with linen or poured into any open container and placed under the bathtub. The substance can be purchased at a pet store and is used as cat litter.

Industrial dehumidifiers are the most effective means for correcting the microclimate in a damp apartment. These devices are sold in hardware stores. When choosing, you should pay attention to power. The larger it is, the more effective the device is. Automation will also be useful. These dehumidifier models turn on and off themselves depending on the humidity level, which helps combat dampness with minimal energy consumption.

Be sure to ventilate the house after washing, bathing and cooking. During the day, there is no need to close the windows with curtains, then the sun's rays will quickly dry the air that has become damp overnight.

Dampness in the apartment cannot be tolerated. It doesn’t matter where the living space is located - on the 1st or 5th floor - it is imperative to find and eliminate the source of the problem. A microclimate that meets sanitary parameters is a necessary condition for the safety of health and property.
