OEM and aftermarkt solutions for automotive repair developer AirSept has announced that it has been granted a patent for its GM Retrofit Cabin Air Filter. Including this new patent, AirSept now holds 30 issued patents.

According to AirSept president Aaron Becker in the press release, GM built over 5 million full-size pickup trucks and SUVs from 2007 to 2014 with a cavity for cabin air filters (CAFs), but with no factory-equipped CAF installed.

“As a result, it is impossible to access the underdash cavity without bending the filter around the transmission bellhousing. Unfortunately, bending a traditional CAF cracks and tears its frame, allowing ingress of pollen, bacteria, dirt, soot and other airborne contaminants and rendering the filter ineffective,” explained Becker.
