The cabin air filter ensures that the interior air coming from the air-conditioning system is clean.

The cabin air filter catches dust, pollen, and other airborne materials which make driving a vehicle unpleasant; including the smell of a vehicle. This makes it a vital element that should be constantly functional.

When you notice reduced air flow through your climate control system or when you smell a persistent bad odor, these are signs that you need a new cabin air filter. Similarly, ensure a regular check on your air filter just to be safe.
