To work with air boosters and achieve the highest efficiency at purification, each HEPA composite filter built with a high-quality pre-filter layer, a fine absorption layer, an activated carbon filter, and a HEPA filter. The HEPA composite filters are capable to remove large particles like dust and harmful ultrafine particles.
• Pre-filter Layer
Made of nonwoven cotton, the pre-filter layer has good air-permeability and is capable to remove large particles of dust.
• Fine Absorption Layer
This layer is made of high-quality tightly-woven materials and capable to remove ultrafine particles.
• Activated Carbon Filter
This layer is made of porous carbonaceous materials with many big holes which enlarge the area exposed to air 20 times. As soon as having a contact with air, it will start absorbing harmful gas molecules. It can absorb large-molecule organic gases like benzene, small-molecule gas pollutants like hydrogen sulfide and formaldehyde, and odors
• HEPA Filter
Composed of a mat of fine fibers, this layer has tiny holes and high absorption capacity. The HEPA filter is effective in removing particles and efficient in purifying. It can remove 99.7% of particles with a diameter equal to or greater than 0.3 µm and 99% of fine particles with a diameter of 2.5 μm (PM2.5), and filter out particles that are 100 times smaller than PM2.5.
