HEPA (High efficiency particulate air Filter), means the filter efficiency reaches 99.97% against 0.3um particle.
The composite filter is a multi-stage combination filter developed for the indoor air pollution, through multi-stage filtration, it can effectively filter out PM2.5, formaldehyde, toluene, allergens, bacterial spores and other pollutants in the air, and provide healthy and high-quality air.
Compared with traditional combined filter, the household composite filter adopts high-efficiency and low-resistance fine filter materials, high-adsorption granular materials and the new CuttonTM antibacterial technology, optimizing the filter production and preparation process, which increase air purifier CADR, CCM and energy efficiency indicators, and can customize various special functional requirements.
