There are umpteen air purifiers in the market to choose from. However, HEPA Air Purifiers steal the show when it comes to keeping the air free of pathogens and dust particles. With lot of fake HEPA Air Purifiers in the market, do you know how to buy the right one? Here is a buying guide for HEPA Air Purifiers to help you purchase genuine air purifiers.

How it Works
Diffusion, Impaction, and Interception are the three ways by which HEPA Air Purifiers work to filter small particles.
•    Diffusion – Here, large particles collide with the trapped smaller particles and thus slow down their movement.
•    Impaction – In this process, particles hit fibers and get stuck.
•    Interception – Minute particles become stuck to the fibers of HEPA Air Purifiers and are removed during circulation of air.

This technology helps filter particles even of the size 0.3 microns. With intricate fiberglass fibers, HEPA Air filters trap airborne particles efficiently to keep the air fresh and pure. This is the reason why these air purifier filters are the best and are mostly used in homes, hospitals, and scientific laboratories.

How to Identify Fake ones
There are lot of air purifier filters with names “HEPA TYPE” and “99% HEPA”. These air purifiers actually don’t work on HEPA technology and aren’t efficient in trapping particulates. Air filters that have these names are not genuine HEPA Air filters. Look for authentic HEPA Air Purifiers to enjoy healthy air.
