Many modern European vehicles are equipped with a cabin air filter. Just as the engine air filter protects the live of the engine, the cabin air filter’s job is to protect us, filtering out harmful airborne particles from the air blown into the cabin. Activated Charcoal filters offer additional protection, and can be differentiated from standard filters by their dark charcoal color. Cabin air filter replacement is an often overlooked service. It is recommended that you inspect a vehicle’s cabin air filter every 12 months or 12,000 miles. If your HVAC system smells funny, this filter is the first place to look.

About this Cabin Air Filter

The BOSCH C3876WS cabin air filter cleans the air coming into the car through the heating and A/C system, trapping dust, pollen and, in activated-charcoal versions, odors. A clogged filter reduces airflow and can cause musty smells.

Frequently asked questions

How often should I replace the cabin air filter?

Follow your car's maintenance schedule, and replace it more often if you drive in dusty or high-pollen areas or notice reduced airflow or odors.

What are the signs of a dirty cabin air filter?

Weak airflow from the vents even on high fan speed, windows that are slow to demist, a musty smell when the fan runs, or a filter that looks dark and clogged.

What is the difference between standard and charcoal filters?

Standard filters trap particles such as dust and pollen. Activated-charcoal filters also absorb odors and some exhaust fumes, which helps in heavy traffic.

Can I replace the cabin air filter myself?

On most cars, yes. It is usually behind the glovebox, under the cowl at the base of the windshield, or under the dashboard. Note the airflow arrow on the filter and fit it the right way round.

How do I make sure this cabin air filter fits my car?

Compare the part numbers listed on this page with the number on your old part or in your vehicle's parts catalog, and check the fitment information. If you are unsure, contact us with your VIN before ordering.
