AirSept Granted Patent for GM-Retrofit Cabin Air Filter

AirSept has been granted a patent for its OEM-approved GM-retrofit cabin air filter. 

The new patent raises AirSept’s portfolio to more than 30 issued patents, according to the company.

From 2007 to 2014, General Motors built more than 5 million full-size pickup trucks and SUVs with a cavity for cabin air filters, but with no factory-equipped cabin air filter (CAF) installed, the company noted.

“As a result, it is impossible to access the under-dash cavity without bending the filter around the transmission bellhousing,” AirSept President Aaron Becker said. “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.”

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 filter opening. The product can be installed in about 15 minutes or less following AirSept’s four-step installation process that requires no special tools, according to the company.

Installing the retrofit filter greatly reduces in-cabin dust and pollutants and extends blower-motor service life, according to AirSept. Standard and extra-odor-protection carbon-filter versions are available. 

“We are pleased that our patent has been granted for this handy retrofit filter that helps promote clean air within the vehicle,” Becker said. “Our product provides repair shops with a beneficial business opportunity.”
