There is a wide range of Hepa Filter offered by us for use in the various applications. The HEPA, which stands for High Efficiency Particulate Air, is a designation used to describe filters that are able to trap 99.97 percent of particles that are 0.3 microns. The offered filters consist of interlaced glass fibers that are twisted and turned in myriad directions to create a fibrous maze. HEPA filter is a type of mechanical air filter; it works by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites, and tobacco smoke.
