One of the basic functions of the body is breathing. We breathe the whole body: the lungs, mucous membranes, and skin are involved in the process. If there is not enough moisture in the air or harmful particles are present, the organs are worse at filtering: for example, the nasopharynx can fully protect against microbes and viruses only when moistened, and the pores of dry skin do not so absorb vital oxygen. Un humidified air has a bad effect not only on humans, but also on the environment – from indoor plants to furniture, natural parquet and paintings. Particularly sensitive to inappropriate environments are small children who are more likely to get sick in a dry microclimate, as well as pets. Fighting with bad air is not only possible, but also necessary, and here comes home climate control.
Special devices help in creating a comfortable air environment for humans: air humidifiers, air purifiers or climate stations, combining the functions of both devices. The former help maintain a normal level of humidity: scientists have determined this indicator at the level of 40-60%, while in the metropolis, especially during the heating season, it drops to 28-30%. Air cleaners filter harmful substances in the air, dust, animal hair, tobacco smoke, and in some cases even viruses, bacteria and gas pollution. Climatic stations combine the advantages of air humidifiers and purifiers, not only maintaining humidity in the room, but also delaying microparticles that are unnecessary for humans.
Traditional and steam
In a traditional humidifier, a fan blows air through a wet filter – usually a paper cassette. These models are the most budgetary, but require additional costs – the filters must be replaced every two to three months. In addition, the noise of such devices is 35-45 dB at a comfortable level for sleep at 37 dB. Steam humidifiers work on the principle of a “water bath”: the water is heated and converted into steam, which naturally moisturizes the air. Such devices require frequent refilling of water in the tank, and, in addition, should only work in conjunction with a hygrometer that determines the humidity level. It is necessary to carefully select the installation location, since hot steam escapes from the device.
Ultrasonic humidifiers are the most high-tech today: in them, water splits into tiny drops, and air is driven through this cloud of spray. Unlike steam, water is not purified in such models – accordingly, they require filters that must be replaced periodically. Among the advantages of an ultrasonic humidifier is a wide range of humidity (from 20 to 90%), automatic control of indoor air, as well as a low noise level (on average – 25 dB).
Management and modes
The control of the device can be either mechanical, with regulators, or electronic. On the models of the latter category, a display often shows the humidity level, operating mode, etc. In addition, they can work in automatic mode, they can delay the start, program various commands, etc. Usually, it is in models with electronic control that you can set the adjustment of modes, temperature or steam intensity. The function of maintaining the set humidity level helps to protect the room from excessive moisture, the shutdown timer allows you to set the necessary time for switching on and off the device, and the ability to adjust the nozzle position allows you to change the direction of steam supply. A remote control may come in handy, especially when the humidifier is high or requires frequent switching of modes.
Room area and humidification rate
Having decided on the type of humidifier, you should calculate its power, which is determined depending on the area of the room and the intensity of humidification. The maximum room area is indicated in the characteristics, and it is worth taking a device with a small margin: if it is necessary to moisten a room of 20 m2, then it makes sense to choose a device with a declared maximum area of 25 m2. As for the performance of the air humidifier, this indicator is measured in milliliters evaporated per hour. For very dry city apartments (10-20%), as a rule, an intensity of 300-400 ml / hour is enough, for medium-sized rooms (30-35%), 200-250 ml / hour is enough. Naturally, the more fumes occur, the faster the water in the tank ends: standard household appliances operating in a city apartment,
