Automotive passenger cabin air filter comprises electrically heated woven carbon fiber core for regular regeneration and extended service life

摘要

The automotive passenger cabin air filter comprises a core woven layer of carbon fiber material with a coating layer of an adsorption agent which may be active carbon particles, zeolite, aluminum oxide and/or silicates. Preferred Features: The particles may be spherical or of irregular shape. The specific surface area of carbon particles is 900-1100 m<2>/g, and 300-900 g/m<2>. The carbon fibers are linked to electrical contacts and are heated for regeneration from time to time.
