Cabin air filters have become increasingly more popular, but some vehicles do not have cabin filters, so you will need to check your owner’s manual to determine if your vehicle has one.

Please reference your vehicle’s owner manual. Cabin air filters are typically found in one of three places:
- Under the hood, near the windshield
- Underneath the dashboard
- Behind the glove compartment

Cabin air filters are used to filter the air that is coming through your vehicle’s HVAC system and into the interior.

Yes. Modern vehicles are sold with an air filter in the engine bay used to protect the engine from contaminants, and some have the addition of a cabin air filter used to filter the air entering your vehicle’s interior. While both types of filters trap contaminants, they are composed of different types of filter media and are not interchangeable.

Your K&N® cabin filter is sold pre-treated and ready to install.

K&N® does not recommend using other detergents or solvents to clean your K&N cabin air filter, as doing so may damage the filter media.

Installing a high airflow filter may help reduce HVAC system strain, which can help preserve your heating/cooling system’s efficiency. Using a dirty or restrictive cabin air filter may put additional strain on your system.
