The cabin air filter (also known as the pollen filter, AC filter, dust filter, hvac filter and hepa filter) in your 2001 BMW 325i cleans the air that you and your passengers breath inside of your car.

These filters are fairly inexpensive, so check out our parts page for great deals on a new one (tip: buy several, when you go to check the cabin air filter on your 325i, you can easily swap it for a new one if it is dirty).
