Air purifiers

Air purifiers differ each from another in types and brands. Air cleaner types depend on the manner and method that is used in order to clean the air from various airborne pollutants. Various companies produce different brands of air cleaning devices. The cost and price of each air cleaner depends very much on the type, efficacy, size, coverage area and brand of the device. In addition, retail prices of the same air purifier may vary from dealer to dealer.

Air purifiers are basically classified due to the method used to eliminate various sized particles and/or gases from the air. The types of techniques available for use in air purifiers include mechanical filters, electronic air cleaners, and hybrid filters for the elimination of particles, and gas phase filters to control odors. There are also air purifiers which produce ozone in order to remove various airborne pollutants. The selection of a type of an air filter depends on the intended use of the air purifier. There are wide applications of an air filter. Air filters are applied in order to protect the HVAC equipment and components, to protect the furnishings decor of inhabited spaces, to reduce housekeeping and building maintenance, to decrease heating equipment fire hazards, and protect the general well-being of residents. The low effective filters in central HVAC systems can be used in order to accomplish most of these requirements. However, to improve the health of residents higher efficiency filters are needed.
