Filter structure, for cleaning air in automobile compartment, has pleated particle filter working with pleated gas filter containing photocatalyst

摘要

The filter structure, to clean the air of an automobile passenger compartment, has a particle filter (40) in a support frame (44) folded into accordion pleats and with a non-woven layer. A gas filter (30), also folded into accordion pleats, has two non-woven layers with a center layer between them composed of a photocatalyst with adsorbent active carbon particles. The folds of the two layers complement each other, to be assembled together into a common filter unit. The assembled filter fits into an opening (52), to move on runners (54) as a sliding drawer.
