HEPA that stands for High Efficiency Particulate Arrestor is a type of air filter used for cleaning the air specially in equipments like vacuum cleaners. These air-purifiers filter the particles in the airborne environment down to 0.3 microns in size and at a speed-rate efficiency of 99.97%. The HEPA air-purifiers with their high-efficiency level have trimmed the usage of age-old air-cleaners. They not only purify the air but also remove even the smallest microns of allergens like dust, smoke, pollen, animal danders, bacteria and other industrial/chemicals effectively from the atmosphere.
Working of the HEPA air purifiers
The HEPA air cleaners work by filtering the allergens in the air through a HEPA air-filter that traps the particles allowing the clean air to return to the atmosphere. The larger number of times that the air passes through the HEPA filters, the better and cleaner becomes the quality of the air. So till date the HEPA purifiers have proved to be the most tried-and-true air-cleaning instruments. The best part about HEPA air-purifiers is that they never emit any byproducts or secondary pollutants such as ozone and ions.
