What is a HEPA Filter? How it works?

HEPA is the acronym for “High-Efficiency Particulate Arrestor”. This filter is manufactured, tested, certified to remove all the impurities from air and make it free from pollutants. According to The Institute of Environmental Sciences and Technology, HEPA filter holds the capability to trap 99.97% of particulates 0.3 microns or larger from the air. The HEPA filter can also trap particles that are about 300 times smaller than the diameter of a human hair. It can also remove PM 10 and PM 2.5 particles from the air. Moreover, the ultra-fine filter captures even the microscopic particles by the combination of impaction, interception, diffusion, and sieving.

The small particles/pollutants collide with the fibers and get trapped while attempting to travel through the bar. The pollutants get grabbed by the fibers via interception.

CADR of HEPA Filter

In order to produce the cleanest air, your air purifier should have HEPA filter in it. When buying an air purifier, you should make sure the HEPA filter has a perfect clean air delivery rate (CADR) that can filter your space where installed. CADR would denote the quantity of air, which passes through the filter and is based on square footage. There might be some rooms that would be too large for the filter to properly clean the polluted air, so, you should always check the CADR of the filter.
