Ultraviolet light: The sterilization rate for bacteria is move than 90.2%.

ULPA filter: It can adsorb particulate up to 0.0001mm like pollen, drifting dust and germ, with purification efficiency of more than 99.99%.

Activated carbon, optical catalyst filter: It can adsorb kinds of smoke and odor, and break down poisonous fumes like formaldehyde and benzene etc., and kill viru and becteria.

Pre-filter: The washable filter can adsorb bigger particulate.

Ozone(optional): The ozone density is around 0.05PPM which can enable production of hydroxyl radicals, and to help oxidize odor, bacteria, mold, chemicals and other pollutants.

Anion: The anion density is more than 5 million ions/cm3 which can combine with the floating smog, pollen and dust in the air.
