AIR CLEANER WITH PHOTO-CATALYTIC OXIDIZER

摘要

An air cleaner comprising an air channel in the air cleaner; an air moving unit configured to create an airflow in the air channel; a photo-catalytic oxidation (PCO) element disposed in the airflow; and a Ultraviolet A(UV-A) Light Emitting Diode (LED) to illuminate the PCO element is described. The PCO element can be a substrate comprising: a first coating comprising a VOC decomposing catalyst; a second coating comprising an ozone decomposing catalyst; and a third coating comprising titanium dioxide.
