Indoor air purification apparatus for vehicle using non-thermal plasma

Abstract

Provided is an indoor air cleaning device for a vehicle using a nonthermal plasma, and more particularly, to an indoor air cleaning device for a vehicle using a nonthermal plasma, in which ozone is generated by a nonthermal plasma through corona discharge and an air purifying filter is sterilized through strong oxidization action of ozone, achieving more hygienic and continuous management, static electricity of an electrostatic filter is recharged with the controlled magnitude of applied voltage to maintain the best purification performance of the filter, and negative ions beneficial for human body are generated, creating pleasant indoor air conditions.
