Changing the air filter regularly helps prolong engine life because the air filter is designed to trap damaging dirt and debris that can damage internal engine parts such as the cylinders and pistons. Engine damage can occur from particles as small as a grain of salt and result in costly repairs. A clean air filter can also increase fuel efficiency and reduce your vehicle's emissions.
The air inside a car cabin can be up to six times more contaminated than the surrounding outside air. With advanced filtering media designed to trap and remove dust, pollen and airborne particles of 1 micron or larger, Cabin Air Filters help provide clean cabin air and assist in maintaining the vehicle HVAC performance.
