The norm of humidity and temperature in the room. Comfortable air humidity in the apartment: methods of increasing and decreasing

One of the main characteristics of a healthy indoor climate is air humidity. A normal level of humidity is very important for a person's well-being. Therefore, it is necessary to know what the normal humidity indicator should be in order to control it and, if necessary, increase or decrease.

Air humidity norm

To assess the microclimate of various premises, relative humidity, measured as a percentage. That is, the ratio of the amount of water vapor in the air to a given temperature is determined environment.

For good health, the optimal humidity level is between thirty and forty-five percent. Permissible rate for residential premises - no more than sixty percent. Such humidity is considered comfortable not only for humans, but also for birds, animals, and even household appliances and furniture.

According to state building codes in residential premises, the humidity indicator should be:

• from 30 to 45% in the cold season;
• from 30 to 60% in the warm season.

The humidity rate also depends on the value of the room:

• in the bathroom and in the kitchen, it should be from 40 to 60%;
• in the living room and dining room - from 40 to 60%;
• in the library and office - from 30 to 40%;
• in the children's room - from 45 to 60%;
• in the bedroom - from 40 to 50%.

In winter, the air in the apartments dried up heating systems and air conditioning in the summer. Along with this, the amount of dust increases, and pathogenic microbes appear that contribute to a decrease in immunity and cause viral diseases.

If there are no air conditioners in the room, then in autumn and summer, at temperatures up to thirty degrees and frequent ventilation, the humidity index of the air in houses and apartments is most often normal.

The value of normal air humidity

A normal humidity indicator in a room helps maintain immunity and human health, as well as keep furniture, things and furniture in good condition. beautiful view indoor plants. However, it is not easy to keep the indicators in the norm. In most houses and apartments, the humidity is lowered for the main part of the year.

If the level is below normal:

1. The nasal mucosa dries up.
2. The process of breathing worsens, as a result of which the body is little enriched with oxygen.
3. The risk of viral diseases increases.
4. Often there is a feeling of drowsiness.
5. Decreased performance.
6. The mucous membrane of the eyes dries up in those who wear contact lenses.
7. Due to the increased dust content in the room, allergic reactions can occur.

Children especially suffer from low air humidity in an apartment or house.

Increased moisture content indoors promotes the formation of fungus and mold, the occurrence of respiratory diseases, reduced immunity, reproduction of dust mites.

In order for the humidity in the apartment to be optimal, it is recommended to monitor its indicators and, if necessary, increase or decrease it.

How to check the humidity in the apartment

To do this, you can use a special device or improvised means.

Humidity instruments

The percentage of water vapor in the air can be found using a psychrometer, hygrometer, or a special household indicator.

More accurate instruments are psychrometers which may be electrical or mechanical.

Hygrometers exist:

Each type of device has its own characteristics, but one base of measurement. Using a hygrometer is very simple - it shows the percentage of the amount of moisture in the room.

Today you can buy domestic weather stations, which are digital thermometers equipped with humidity indicators. With the help of such a device, you can find out not only the humidity in the room, but also the ambient temperature, as well as upcoming changes in nature.

Folk remedies

If there is no special device for this device at hand, then you can use improvised means.

For example, you can use a glass of water, which will need to be cooled in the refrigerator for five hours. After that, the glass is pulled out and placed on the table away from the radiators:

1. If after five minutes a glass of water remains misted, then the microclimate in the apartment is normal.
2. If trickles flow down it, then the humidity is increased.
3. If the glass has time to dry in five minutes, then this indicator is lowered.

You can estimate the humidity level in a room using tables Assmann and thermometer. To do this, having fixed the temperature that the thermometer shows, it will need to be wrapped in a wet cloth and wait five minutes. After that, the tissue is removed, and the result obtained on the thermometer is recorded.

In the Assmann table, the dry thermometer readings are shown vertically, and the difference between the two indicators is shown horizontally. At the intersection will be the humidity indicator of the room.

You can build a "hygrometer" yourself, taking for this spruce bump and fixing it with tape or a carnation on plywood. Then you will need to watch her:

• if bump long time will lie unchanged, then the humidity in the room is normal;
• if her scales quickly begin to open, then the indicator is lowered;
• if even after a day the tips of the scales do not rise at least a little up, then the humidity in the apartment is high.

You can determine the moisture content by indoor flowers. From them it is easy to find out that the air in the room is dry. If in Fatsia, Asplenium, Diefenbachia, Dracaena, Ficus, the tips of the leaves dry up and even spraying does not help, then there is low humidity in the house or apartment.

You also need to listen to your feelings. At an extremely low rate, irritation and constant dryness in the throat and nose may occur.

For a comfortable microclimate in the apartment, you must:

• regularly do wet cleaning;
• ventilate the room;
• grow indoor plants.

If the humidity level is low

Most often in winter time years in an apartment humidity index lowered. To normalize it, you need to take measures:

But most modern way increasing moisture in the air is special humidifier, into which water is poured, evaporating during operation of the device.

Traditional Humidifier equipped with a fan that drives air through the water tank and at the same time cleans it from dust and moisturizes.

IN steam humidifier water boils and steam comes out. You can even use it for hard or dirty water. Such a device can be sold with built-in nozzles and used as an inhaler.

ultrasonic humidifier Water is converted into steam using a special membrane. With it, you can fight germs in the room. However, only distilled water should be used for it, or special cartridges should be installed that will soften and purify the water.

If the air humidity is high

Dehumidifiers can be portable and stationary, which are mounted into the wall and have a large capacity.

An oil cooler can also be used as an air dryer. m equipped with a fan.

The kitchen and bathroom need install hoods. They will help fight moisture and excess odors.

If the humidity index is increased, then it is not recommended to dry the washed laundry in the room, and the sink and bath should be wiped immediately after use.

But, with any indicators of air humidity, it is necessary to ventilate the room as often as possible. Oxygenated fresh air kills bacteria, fungi and neutralizes dust mites. And most importantly, it normalizes the humidity in the room, while establishing a comfortable microclimate for a person, which is so important for health and well-being.

The right microclimate in apartments and houses is a guarantee of good health and well-being of each family member. Wrong climatic conditions in a residential building and each of its rooms individually can lead to serious illness. That is why every homeowner needs to know what are the norms of indoor air humidity, what is the danger of an increased or decreased indicator, how can the level be adjusted.

Influence of air humidity

Assessing the parameters of the air in a home, many people first of all pay attention to its temperature, completely forgetting about the more important parameter - humidity. It is this criterion that creates a feeling of cold, stuffiness or heat, forms general state residents of the house, is responsible for the safety of indoor plants and household items, finishing materials, appliances and other interior items.




The degree of humidity directly depends on the geographical location and regional climate, season, weather outside. In winter, this figure decreases significantly, while in summer it rises. To prevent interior items from becoming unusable, you should adhere to the norms of indoor air humidity.

How to measure air humidity



Seasonal benchmarks

According to GOST standards, acceptable indicators humidity are indicated for residential buildings by season or are regulated depending on the purpose of the rooms. IN summer time this parameter can vary within 30-60%, but should not exceed 70%. In the cold season, this figure is significantly reduced to 30–45% (maximum permissible value cannot exceed 60%.

It is worth noting that these humidity standards in residential premises are more relevant for developers and designers whose task is to erect and maintain construction projects. Compliance with indicators allows them to extend the operational life of buildings.



Norms for individual premises

Seasonal standards show that during the cold season, the level of humidity in a house or apartment decreases. This trend is due to moisture entering the living quarters with outdoor air and which is reduced to room temperature. Despite this, a person needs normal indicators at any time of the year. Whether it's the heating season or the hot summer.

If the question arises, what should be the normal humidity in the apartment, it is worth adhering to the average parameters that do not depend on the time of year or the purpose of the room, which are 40-60%. For individual rooms, there are their own moisture standards:






It should be noted that depending on the situation, the indicators may change. For example, in a nursery, when a child is sick with acute respiratory infections or other infectious diseases, viral disease, the humidity in the room should be approximately 70%, while the air temperature cannot exceed 24 ° C.

How to determine the humidity of the air at home? Lesson #4



Methods for measuring moisture levels

To find out the humidity at home, you can use one of four proven methods. The most reliable information is shown by a hygrometer - a special device for measuring the level of moisture inside rooms. If there is no such device in the house, you can use improvised means, although they give a relative result that may differ slightly from the real parameters, but they can still show whether it is worth increasing or decreasing the humidity.

Four ways to measure indoor moisture levels:



DIY air dryer * ECONOMY OPTION *

In such simple ways, every homeowner will be able to find out in just a few minutes what humidity should be in the room, based on the results obtained.

Parameter Boosting Methods

During the heating season, every homeowner has to deal with the problem of drying the air in an apartment or house. In summer, the humidity decreases due to the operation of air conditioners. Special devices sold in hardware stores, or folk ways to increase humidity parameters will help to solve this problem.

Special devices

They are in the greatest demand among owners of apartments and houses. The principle of operation of such devices is to evaporate water and supply it through a special tank into space, which makes it possible to compensate for the lack of moisture in the air. There are three types of such devices on the market:



If necessary, the homeowner can purchase a universal steam device that allows you to turn a simple humidifier into an inhalation device thanks to the nozzles included in the kit.

Home Tricks

If the owner of the apartment does not have a special humidifier, then you can resort to folk ways increasing the level of humidity. Such "old-fashioned" methods will help saturate the room with the missing moisture without the cost of expensive devices:



An alternative option could be an aquarium with fish, which is important for rooms with a small square. Regardless of the method chosen, one should not forget that dry air has a bad effect on human health: it leads to dry mucous membranes, skin, puts an unbearable burden on the heart, disrupts digestion and worsens air quality.

Home dehumidifiers

Such devices can be fixed and portable. The performance of the devices is calculated by the number of daily use of the amount of liquid and can vary between 12-100 liters. There are only two types of air dryers:

1. 1. Compressors, the principle of operation of which is to distill moist oxygen through fans. After air enters the unit, it is drawn through the evaporator, and the settling moisture accumulates in a special receiver.
2. 2. Adsorption, which are often called. The stationary device is characterized by low power consumption and noiselessness. Inside the device is an adsorbent that absorbs moist air. When buying such a device, it is worth considering the additional expenses that will be required to replace the cartridges.

The use of air dehumidifiers is also relevant in winter, they are installed in rooms where there is no heating. The device has the advantage of automatic shutdown when the maximum amount of liquid accumulates in the receiver.

Folk methods



Many homeowners install oil-filled radiators or multi-functional air conditioners with a built-in moisture control function in their apartments to reduce the level of humidity in the air. Despite this, there are cheaper, proven methods for drying the air. For example, ventilation sunlight or installation of hoods in unventilated rooms, lit candles.

Do not neglect the indicators of air humidity in an apartment or house, they must comply with GOST standards. Otherwise, high rates can lead to chronic respiratory diseases, unpleasant odors, constant irritability and fatigue, dampness of things and so on. A healthy microclimate that meets the standards has a positive effect on the well-being of households and extends the operational life of equipment, furniture, and interior items.

Assessing the parameters of the air in the house, 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. We will figure out what is the norm of air humidity in the apartment, and also find out what it affects.

The humidity indicator reflects the degree of saturation of the air with water vapor. It is 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 real 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 microclimate in the room. Both the person and the home environment suffer from excessively high or too low humidity.

Dry indoor air provokes increased moisture loss through the skin and respiratory tract. This may lead to such backfire, How:

• decrease in the 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, a feeling of "sand";
• thickening of the blood, leading to a slowdown in its circulation, weakness, headache, decreased performance, increased stress on the heart;
• an increase in the viscosity of gastric and intestinal juices, provoking a slowdown in digestion;
• drying up of mucous membranes 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 reproduction of mold, fungi, bacteria. As a result, residents of the home may experience:

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

Excessive or insufficient moisture has a bad effect on the condition of objects home furnishings. Plants dry out or begin to rot wooden furniture and the parquet is deformed or “shrinks”, the 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 large quantity it can contain water vapor as much as possible, and vice versa. But when assessing relative humidity, an inverse relationship works: the warmer the air, the lower its relative humidity will be with the same volume of water vapor in it. Therefore, airing in winter makes the air fresher, but less humid. Optimum temperature considered 18-22 ºC.

Water vapor from the air in the room is "taken away":

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

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

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

Regulatory 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%, the maximum allowable - 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 norm 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 the children's room is 50-70%. If the child is sick with ARVI or an infectious pathology, then this parameter should not be allowed to decrease by less than 60%.

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

How to measure relative humidity?

Knowing how to be optimal humidity air in the apartment, 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 device - electrical, chemical, condensation, hair and others. For an apartment, you should not buy an expensive professional device. The simplest hygrometer with an error of 3-5% is enough. Often it is combined with a clock and a thermometer. It is important to place the hygrometer away from sources of moisture and heat.

You can determine the 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 send the vessel for 3 hours in the refrigerator. Next, you need to put the glass on the table away from the battery and watch it for 5 minutes. At the same time, condensation forms on its walls due to temperature differences. Possible results:

• the glass dried up within a few minutes - the humidity is lowered;
• the walls remained foggy - the microclimate parameters are normal;
• trickles of water flowed down the glass - there is 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 conventional one and a humidifier. Its likeness can be made at home. You must first measure the temperature in the room with a conventional alcohol thermometer and record its value. Then you should wrap its end with a damp cloth. After 5 minutes, you need to re-measure the temperature. She should go down.

Next, you need to look at the Assman table. The readings of the “dry” thermometer are located vertically, the temperature difference is located horizontally. Seeing desired values, find their intersection. This will be the relative humidity.

fir cone

Note: Indirect signs of low air humidity in the room are the drying of the tips of the leaves of plants and electrical discharges emanating from synthetic clothing.

Humidity regulation

At any time of the year, the normal humidity in the apartment should be at least 30-40% and not higher than 65%. How to regulate it?

Ways to reduce humidity:

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

Humidity increase methods:

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

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

plus

The norm of air humidity in the apartment must be constantly maintained. Due to the dry air that forms after turning on the batteries in winter, dust spreads faster, dust mites appear, and respiratory organs can be irritated. Such an atmosphere has the greatest impact on children, asthma develops. In addition, excess water or lack of it in the air affects the formation of fungi on the walls, the development of plants and the durability of furniture.

The effect of dry air on people

Humidity is the amount of water vapor contained in the air. Its level is affected by the temperature in the rooms. The average norm is 45%, and it can change based on the direction of the room:

• dining room - 40-60%;
• bedroom for adults - 40-50%;
• room for a child - 45-60%;
• work zone with books - 30-40%;
• kitchen or bathroom - 40-60%.

Rarely, without any devices, it is possible to remain within the normal range. And too high or low humidity leads to disastrous consequences for human health, the condition of repairs and furniture, as well as for pets and plants.

Dry air, which appears most often with the onset heating season, leads to irritation of the mucous membrane of the nasal cavity and throat, and can also begin to dry the skin and hair, and children develop asthma.

Due to dryness, static electricity is generated, which raises dust, dust mites and many germs can appear. Too humid air also has a bad effect on the human body, and fungi and mold can form on interior items, walls and ceilings.

Note! Due to the overdried air, the human body is cooled, as there is a large loss of fluid.

It is because of such harmful effects on a person, an apartment and flowers that equipment has been developed that maintains the required level of moisture.

What device to measure the humidity of the air in the room to use

To understand whether the norm of air humidity in the apartment is being met, special equipment is used - a hygrometer. It is easy to use and shows the result as a percentage.

Important! The average reading should be within 40-60%!

If there is no special device, use folk remedies. The measurement accuracy will be lower, but strong deviations from the indicator that the air humidity in the apartment should correspond to will be shown.

There are several methods:

• The use of a thermometer and Assman's psychometric table. To do this, first fix the temperature in the room, then wrap the end with mercury with a damp cloth and check the data after 5 minutes. If the readings are higher, it is necessary to repeat the procedure by better wetting the rag. After receiving the data, check it with the table.

• Fill up a glass cold water and refrigerate for three hours. The temperature of the liquid should drop to 3-5 degrees. Position the container away from the batteries and watch for changes on the glass surface. If fogging occurred at first, and after 5 minutes. the walls are completely dry - lack of moisture in the room. If the glass remains misted, then you have an optimal state of humidity in the apartment. When streams appear, it exceeds the norm.

• Another way to measure the humidity in a room using improvised means is to use spruce branch, 20–30 cm long. It is necessary to fix the cut on the board and mark the location of the free tip. When wet, the branch will drop. Now every day, watch the weather forecast and write down the data on the board, while watching the changes in the spruce. Yes, after a few days homemade hygrometer, which can be used without a weather forecast.

• The norm of air humidity in an apartment can also be determined by a spruce cone. Put it away from the heating system and watch for changes. If the level is increased, the scales will press against each other, if vice versa, they will expand.

Such options will not give measurement accuracy, but will show a strong increase or decrease in humidity.

The norm of air humidity in the apartment: how to put the indicators in order

You can change the indicators up or down using certain equipment or folk methods. In any case, it is necessary to do this, especially if you have children.

We increase indicators

To get the norm of indoor air humidity when the air is too dry, you can use a humidifier or folk methods. A simple device is designed for an area of ​​​​up to 150 sq.m. For its operation, it is necessary to pour water into the container, which will evaporate.

Such devices are divided into three subgroups:

• Traditional. They work using a fan, they drive air through the water compartment, where dust is removed and moistened. The device is quite noisy and can raise the level to 60% as much as possible.

• Steam, which works like a kettle, that is, it heats water to a boil. The disadvantage is that hot steam is produced, a lot of noise and electricity consumption. However, it is possible to increase the humidity level above 60%.

• Most modern version – ultrasonic humidifier. Works not so noisy, able to fight germs. There is a drawback - in operation it is necessary to use only distilled water, otherwise the equipment will need to be repaired or replaced.

To increase the humidity in the room, you can use folk remedies:

• put a wet rag on the radiator;
• install a container of water on the battery;
• drying clothes;
• installation of an aquarium and an increase in the number of indoor plants;
• can be mounted decorative fountain;
• insulate the apartment.

You can choose any suitable method to increase the humidity if, after measurements, you find that the air in the rooms is dry.

Devices that provide the necessary atmospheric humidity are not cheap. It turns out there is simple ways solve this problem on your own.

We reduce indicators

Not only dry, but also humid air adversely affects human health, as well as household items and repairs. To reduce the water vapor content, there are special devices that can process from 12 to 300 liters of water per day.

They are portable and stationary. Even in the pools, powerful stationary devices are installed so that mold and fungus do not form. At the same time dehumidifiers can work also in cold rooms. During operation, it is necessary to periodically change the water containers, which are filled in the process.

There are options with adsorbing substances, where there is no container, and moisture is absorbed into them, but the power of such devices is limited, and the performance is calculated only up to 20 sq.m.

The easiest way to reduce the humidity in the apartment with folk remedies is frequent airing. And in the bathroom and toilet - installation of a ventilation system. There are also models of oil radiators that not only increase the temperature in the room, but also reduce humidity. For those who like to do everything with their own hands, you can mount a whole ventilation system around the apartment or make a dehumidifier with your own hands.

In custody

Having figured out what air humidity is considered normal in an apartment, and having measured it, it is necessary to bring the indicators back to normal, since deviations have a bad effect on a person and interior items.

You can use special equipment or folk methods to obtain data on the level of humidity. Readings should be taken in each room separately. Do not forget to ventilate the room, as this is good for health and affects the amount of water vapor in the air in the apartment.

Tsugunov Anton Valerievich

Reading time: 5 minutes

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

How does high and low humidity affect a person?

Both high and low humidity most directly affect the life and health of the inhabitants of the apartment.

high humidity

Consider the situation when the humidity in the apartment is increased.

• If the air is too humid, the temperature is perceived differently by the body. The process of heat transfer is disturbed, at high temperatures the body overheats, at low temperatures it becomes supercooled.
• This phenomenon, combined with high temperature indoors is especially dangerous for people suffering from hypertension and cardiovascular diseases: it leads to dehydration and chemical imbalance, blood clotting, high blood pressure and exacerbation of chronic diseases of the heart and blood vessels.
• High humidity adversely affects physical and mental activity, even completely. healthy person, since fatigue in such conditions occurs much faster.
• 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.
• The increased moisture content in the air is dangerous for allergy sufferers. situation during wet rooms very favorable for the appearance of - powerful allergens that can lead to really adverse effects on the body, not to mention that they spoil appearance and decoration of the apartment.

In addition to fungus and mold, high humidity contributes to the development of various pathogenic microorganisms and insects. Furniture deteriorates from it, an unpleasant musty smell appears.

Reduced humidity in the apartment has the following consequences:

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

What is the optimum air humidity?

Both excess and lack of moisture in the air carries a danger to the health and condition of the apartment. What should ideally be the humidity in a residential area?

• To make it comfortable for a person to be in a room, the humidity of the air should be from 30 to 60%.
• Comfortable air humidity in the apartment during the cold period is about 30-45%.

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

The normal humidity in the apartment is great importance not only for people, but also for various objects. For example, for indoor flowers, furniture and books optimal indicator- 40-60%, for household appliances - 45-60%.

How to measure the level of humidity in the apartment?

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

Glass of water

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

Pour into a glass of water and put it in the refrigerator for several hours. During this time, the water temperature should drop to 3-5 ° C. Then put the glass in the room 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, then the air in the room is dry.
• If the glass remains foggy, the humidity in the room is at an optimal level.
• The streams flowing down the walls of the glass will help you learn about high humidity in room.

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

What to do if the humidity is too high?

So, we have learned to determine the degree of humidity in the premises. Suppose you get a result indicating that it is too high in your room. What will help in this case?

• Air Dryer. This device will allow as soon as possible get rid of humidity in the apartment. The dehumidifier can be portable or stationary.
• Moisture absorber. It usually takes the form of a tablet made from a special absorbent.
• Hood. Unventilated rooms where moisture constantly accumulates are best equipped with exhaust devices: a ventilation duct,. With a poorly functioning hood in the apartment, 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. tributary fresh air also helps to 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 the humidity is to put a humidifier in the room. This device is capable of influencing the air in rooms up to 150 square meters in size. m. The principle of its operation is simple - it is necessary to pour water into a container specially designed for this, which the device will evaporate, saturating dry air with water vapor. There are three types of humidifiers:

• Traditional (cold type). Have simple design with moisturizing 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 bring it out in the form of steam. Pros: high performance, no Supplies, the ability to work with plain water from the tap. Cons: Enough high level noise and power, steam that can burn you (up to 60 degrees).

• Ultrasonic. Considered the most modern, their work is based on the oscillation of a membrane that turns water into cold steam. They work almost silently, allow you to adjust the level of humidity. Some models heat water, killing germs and bacteria. The disadvantage is the exactingness in care, the use of cartridges that need to be replaced regularly, or distilled water.
