Often air in the apartment can be polluted stronger, than on the street. Because indoors, as a rule, more dense concentration of hazardous substances from different sources, such as furniture, carpet and paint coats, textile products, pets. These problems with the help of air purifiers are solved. To choose suitable model of the air cleaner, it is necessary to study all characteristics of this device at first.
By the principle of work the device of the air cleaner reminds the advanced fan with the filter which involves the polluted air and releases cleaned. Main functions of the air cleaner: removal of dust from air; elimination of flower pollen; delay of large particles from air (for example, hair of animals); cleaning of air from tobacco smoke; elimination of unpleasant smells; destruction of pathogenic viruses and bacteria.
Types of air purifiers
There are several types of air cleaners in which different technologies of cleaning are used. Generally models of cleaners differ as the built-in filters. The simplest is the mechanical filter which purifies air from large particles. The filter of electrostatic type contains plates with negative charge which attract dust particles with positive charge. Charcoal filters absorb any unpleasant smells and involve hazardous substances. Models with NERA-filters which are capable to purify air from the smallest polluted particles and allergens are very effective. And the latest cleaners with photocatalytic filters influence the polluted air by means of ultra-violet radiation that gives the chance to purify air not only from dust microparticles, but also from pathogenic viruses and bacteria. Also there are devices with additional functions: cleaners with humidifiers, cleaners ionizers (restore balance of negative ions in air) and cleaners ozonizers (enrich air with ozone).
According to what criteria it is necessary to select the air cleaner
First of all it is necessary to consider how qualitative has to be cleaning. If, for example, someone from family members has allergy, then it is necessary to choose more powerful model of cleaner. Power also depends on the room size - than it more, those more powerfully need cleaner. Models with humidifiers are necessary in rooms where damp cleaning is seldom carried out therefore air becomes dry and accumulates more dust. And cleaners with ionizers and ozonizers considerably improve air quality and do it useful to health. When choosing model of cleaner you should not forget that the device during operating time publishes noise which can disturb the people sensitive to foreign sounds (pensioners, small children). In that case it is worth paying attention to more silent models. Optimal variant for the apartment is the air cleaner with humidifier. After cleaning and moistening, air becomes clean, fresh, soft and without foreign smells.
