AirSept was granted a patent for its OEM-approved GM Retrofit Cabin Air Filter. According to AirSept President Aaron Becker, GM built more than 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,” Becker explained.
AirSept’s GM Retrofit Cabin Air Filter features a segmented frame that bends to go around obstacles, then straightens as the technician inserts it in the CAF opening, according to the manufacturer. The product can be installed in about 15 minutes or less following AirSept’s four-step installation process that requires no special tools. The company noted that installing the retrofit filter greatly reduces in-cabin dust and pollutants and extends blower motor service life. Standard and extra odor protection carbon filter versions are available.
The new patent raises AirSept’s portfolio to more than 30 issued patents.
