The norm of air humidity in the apartment: how to measure it and what it affects


The norm of air humidity in the apartment must be constantly maintained. Due to the dry air that is formed after turning on the batteries in winter, dust spreads faster, dust mites appear, and the respiratory system can also 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 area 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 beginning of the 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 a glass with 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 a spruce branch 20–30 cm long. You need 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. So, after a few days you get a homemade hygrometer that 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%.

  • The most modern option is an 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;
  • you can mount a 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.

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 capacity, 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.
