HEPA air purifiers are very popular in the market. HEPA is the abbreviation for High Efficiency Particulate Arresting. These air purifiers remove particulates that are suspended and minute from the air, thereby purifying the air from all particles that are suspended in air, and may be a potential harm causing agent or an agent that may cause various allergies to people inhaling them.
Fiber or polymers are basically used to make these purifiers. The microscopic particles in the air are trapped by these constituents. These purifiers are very capable of trapping dust, mold spores, many varieties of viruses and bacteria. Many varieties of these purifiers are present in market and majority of them are known to have 99.97% effectiveness in filtering particulate matter as tiny as 0.3 microns. But the fact is that the HEPA purifiers only filter airflow that goes through it, hence this particular claim may be untrue in most cases. This is due to the fact that many of these purifiers are not very well designed and may allow the air to pass around and hence miss the filters, and in effect still remain in the room without going through the cleaning process.
HEPA air purifiers usually use an active material of which is carbon based to help in the absorbing of chemicals, gases and odors. There are many kinds like thin mats of Air-O-Swiss filters or several pounds seen in the Austin Air Purifier.
HEPA air purifiers are used specifically in vacuum cleaners. The usage of HEPA air purifiers in vacuum cleaners allows trapping of pollen and dust mites, which can reduce the asthmatic and allergic effects on those who are suffering from breathing problems.
Even though air purifiers are very effective, while buying purifiers, it is better to buy only HEPA filters and not 99% HEPA or other HEPA TYPE filters. This is only because HEPA air purifiers are the only ones effective and the results provided by the rest cannot even be compared with the ones produced by HEPA air purifiers. Nowadays sealed HEPA air purifiers are available too, which do not allow leakage of air without being filtered, thereby increasing the efficiency.
