How do HEPA filters work?

HEPA air cleaners are a type of air cleaning devices that uses a cloth filter (HEPA stands for - high efficiency particulate air) to trap micro particles as the air moves through it. These filters are able to remove almost every harmful substance from the air of mechanical and biological nature. HEPA air purifiers are very popular among regular people as a perfect air cleaning system for their houses, because they are very safe, effective and not expensive.

Effectiveness of HEPA air purifiers

HEPA technology is able to remove at least 99.93% of airborne particles. But you must be careful not to buy air filters that claim to have a so-called "HEPA-type" or "HEPA-like" technology, which means that these devices have not been accredited for their effectiveness, and they haven't been tested by independent laboratories to satisfy the requirements common for HEPA filtering technology.

The drawbacks of HEPA air cleaning systems are considerable noise that can be annoying for some people. They usually use replaceable filters that can last up to a few years, depending on the level of air pollution in your house, but sometimes HEPA filters can not be replaced, and you should be careful to find out this detail before purchasing your air purifying system. HEPA filters are the best for capturing allergies, bacteria and mechanical particles from the air. And once captured, they are never released in the air. But they are ineffective against gas pollutions, fumes, odors and cigarette smoke.

This is why the best air purifier is the one that combines different technologies, thus offering you advantages of various cleaning system within one machine: HEPA filters with activated carbon air purifiers, HEPA systems with air ionizer, and others.
