By now, you’ve probably heard of air purifiers. But what is a HEPA filter and why is it so efficient? Let’s see what is a HEPA air purifier and how does it work?
What is a HEPA filter?
A HEPA filter, as its name suggests, filters air (particulates) with high efficiency. According to theory, it can filter out 99.97% of all particles with a particle size of 0.3µm (microns); this specific micron-sized particle is called the most penetrating particle size (MPPS) by scientists; this size of particles Better to avoid air filters than larger or smaller particles.
Why does HEPA filter has such high efficiency?
HEPA filters are basically a mixture of tangled fibers composed of polypropylene or glass fibers with diameters between 0.5µm and 2.0µm. HEPA filter blocks particles using 3 different methods based on particle size.
Where are HEPA filters used?
As we have already mentioned, HEPA filters have a wide range of uses. But its most common application is in household appliances such as air purifiers, vacuum cleaners, air conditioners, etc. It can also be used in car air filters, airplanes,…
When looking for a product with a filter, one thing to look out for is the efficiency of the filter. This efficiency is reflected in the MERV rating. MERV, or Minimum Efficiency Reporting Value, primarily reports the ability of a filter to capture particles ranging from 0.3µm to 10µm (microns).
