AirSept has been granted a patent for its OEM-approved GM Retrofit Cabin Air Filter.
GM built full-size pickup trucks and SUVs are built with a cavity for cabin air filters (CAFs) but no CAFs are installed.
“It is impossible to access the under dash cavity without bending the filter around the transmission bell housing. 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,” said AirSept president Aaron Becker.
AirSept’s filter features a segmented frame that bends to go around obstacles, then straightens as the technician inserts it in the CAF opening.
The new filter can be installed in about 15 minutes and requires no special tools.
