Specifications:

Negative ions will adsorb suspended particles in the air (such as PM2.5, formaldehyde, pollen, second-hand smoke, pet hair, etc.), make these suspended particles attract each other, become larger and heavier, and accelerate landing. The Doumeng purifier continuously uses 3 million / CM3 negative ion mouth and nose, like forming an invisible mask, which can effectively reduce the suspended dirt inhaled and avoid the danger of dirty air.
