The negative ions released by negative ion tiles can decompose harmful gases such as formaldehyde and toluene released by indoor furniture, floors, paints, and other building materials through the redox reaction of electrons.
Negative ions can decompose irritating gases such as ammonia gas, and at the same time use the adsorption effect of negative ions to make the dust in the air attract each other and become larger, from floating dust in the air to large particles of dust falling to the ground.
