STRUCTURE
HEPA filter is made of a mesh of randomly arranged glass fibers with a small diameter of about 0.5 – 2 micrometers. With such a small size, the filter can easily catch ultra-small dust particles that other filters cannot catch.
Because the structure of the HEPA filter is quite sophisticated, it also performs an extremely important function. On the air purifier, this filter will help filter out bacteria, animal hair, pollen, dust or other agents that affect health.
