You may have wondered what the reference to HEPA means while trying to select an Air Purifier for your home or office. Let's find out.
HEPA stands for the High-Efficiency Particulate Air Filter; a true HEPA filter can capture at least 99.97% of particles with a diameter greater than or equal to 0.3 microns. They can filter out impurities and particles in the air, such as:
- Respirable dust
True HEPA Filterswere initially used in the medical field, in operating theatres, intensive care units, laboratories, clean rooms, analytical laboratories, then airplanes, and many other places where clean, healthy air is essential.
The HEPA filter is made from fiberglass or filter paper. It can retain the microparticles with a scattering effect and slows inertia even under challenging environments.
