Included in the kit are HEPA composite filters which have four filter layers. 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 sulphide and formaldehyde, and odours
  • HEPA Filter: Composed of a mat of fine fibbers, 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.
