Cabin air filters are relatively new, so not all vehicles have them and some people confuse their cabin air filter with the engine air filter. Every vehicle has an engine air filter that cleans the air going into the engine, but not all have a cabin air filter, which cleans the air going into the passenger compartment.

The cabin air filter screens out dust, pollen, spores, smog, and other harmful pollutants and allergens. For comparison, a grain of sand is about 200 microns in diameter, but a cabin air filter can stop particles that are 3 microns in size.

A dirty cabin air filter only needs to be replaced. Your owner's manual may have a recommended interval for changing it, but we can inspect it also. Many people ironically do not realize they have a cabin air filter until the passenger compartment starts to smell bad.

Some cabin air filters are easily accessible, but others may require additional efforts if found in difficult places like behind the dashboard. Ask us to change your cabin air filter right away.
