Air conditioners with formaldehyde filter

Formaldehyde filter

— it is a specialized filter for removing formaldehyde and some other harmful organic compounds (eg ammonia, benzene and/or hydrogen sulfide) from the air. The source of such substances can be both external pollution (for example, emissions from industrial enterprises), and some items in the room itself: new furniture or curtains, some types of floor and wall coverings (immediately after application), spoiled food, cigarette smoke, etc.

The specific principle of operation of filters of this type may be different. The most commonly used so-called cryocatalytic element, in which the catalyst decomposes organic matter into simpler harmless components, and then restores its properties due to cold when the air conditioner is cooling. In addition, many catalytic (photocatalytic) filters have similar capabilities (see the relevant paragraph), so one such element can be claimed in the characteristics of two types of filters at once — both catalytic and formaldehyde.
