BMW M3 Cabin Air Filter (328i, M235i, M4, & More) - Symptoms, Benefits, And Product Review

Blog Feature

If the inside of your car is smelling old, moldy, or musty, it might not be your fault. It might be your cabin air filter and, lucky for you, it's one of the easier parts you can replace on your vehicle. 

Cabin air filters are an often overlooked item that should be replaced regularly. They help filter out dust and other contaminants from getting into the air ducts. We recommend replacement once a year (which is the perfect way to take advantage of our Lifetime Replacement Guarantee). If your cabin air filter has never been replaced, there's a good chance it's completely clogged full of dust and debris.
