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 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.

Consumers have to purchase these air purifiers with precaution as there are many products available in the market with names such as HEPA Type, HEPA-like and also 99%HEPA! These products do not even come close in comparison to original HEPA filters as originals have been designed in a way that no air can leak while passing through it. These air purifiers also use the name ‘Sealed HEPA’.
