The cleaning principle of negative ions is that a built-in generator uses a high-voltage carbon fiber brush system to release a large amount of negative ions into the air. The released negative ions attach to air molecules and polluted particles in the air, giving them negative electrons. The negative electrons repel each other and move away from the breathing range. They are attracted to positive electrons, and the large particles sink to the ground due to gravity, preventing them from adhering to the mucous membranes of the throat and nose, and effectively protecting healthy air from entering the lungs. It brings fresh air like being in a forest every day. [No noise] Pet odor elimination.
