With advanced filtration system
The advanced filtration system eliminates harmful agents in two stages: In stage 1, the activated carbon filter acts as pre-filter to catch big particles like human hair and regular house dust, and effectively removes odors and harmful gases. In stage 2, the HEPA filter filters out fine dust, bacteria and allergens.
