The WIX Filters XP Cabin Air Filters feature PUR-AIR technology that filters virus aerosols as well as odors and allergens. The PUR-AIR technology is a multi-layer protection that filters out up to 99 percent of allergens, like pollen and fine dust, absorbs odors, gases and pollutants, and mitigates viral aerosols passing through the vehicle’s ventilation system, the company says. The XP Cabin Air Filter is available for most popular passenger vehicles and can be installed in about 20 minutes.
