Which HEPA Air Purifier?

HEPA is a popular household name as its full form is High Efficiency Particulate Arresting air purifiers. These air purifiers are used for the removal of minute particles that are found in the air and so help in the “cleaning” of air around you. This reduces the risk of allergies for many.

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 also use material made out of activated carbon. The activated carbon filters absorb chemicals, gases and odors. The material may either be a thin sheet of activated carbon or pounds of compressed activated carbon in containers.

These purifiers are often used in vaccum cleaners as they are highly beneficial to people suffering from allergies, like asthma as they trap dust mite fences and pollens which are proven to affect susceptible people.

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.
