Abstract:
A multi-function air treatment apparatus, comprising:a generally enclosed housing in which an interior and a plurality of through openings are defined, at least one of the through openings being an air inlet through which air enters the housing and at least one of the through openings being an air outlet through which air exits the housing; a negative ion generator positioned within the housing, the negative ion generator having an enclosed charged surface and an opposite outer surface on which negative ions are generated and from which the negative ions are transferred to the air via a negative electrostatic field; and a photo-ionizing assembly positioned within the housing, the photo-ionizing assembly having a light source that produces light at a desired wavelength to react with airborne matter, wherein negative ions generated by the negative ion generator interact with and neutralize positively charged airborne particles and the light from the photo-ionizing assembly causes oxidation of at least some of the airborne matter in adjacent air within the housing.
