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 Filters were 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, low bacteria, 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.
True HEPA filters are now used in air purifiers for homes and offices because people are more concerned with clean air quality. HEPA filters are also found in vacuum cleaners, medical equipment, car engines, and smoke/fume extractors.
Do I really need a 'True' HEPA filter?
To qualify as a 'True' HEPA filter, it has to be able to remove particles less than 0.3 microns in size. An air purifier without 'True' HEPA technology will not remove as much airborne contamination.
If you want your family to be protected, True HEPA is exactly what you need.
