What is my Cabin Air Filter?
The cabin air filter cleans the air coming into the cabin area where the passengers are located. The filter catches pollen, dust, insects, and airborne particles that may be unpleasant to smell or ingest. In most vehicles, the cabin air filter is located behind the glove compartment, but some manufacturers find other spots to install the filter. For your vehicle’s cabin air filter location, consult the vehicle owner’s manual.

The cabin filter works as an in-home central air conditioning filter. It catches the debris before it comes into the vehicle and becomes a problem for the passengers. Over time the filter will become full of debris and need to be replaced. The frequency needed to replace the cabin air filter depends on many factors such as: how often you drive the vehicle, the air quality, whether people smoke in the car, etc.

At Bob & Sons Automotive we check the cabin air filter at each service to ensure the quality of air coming into the cabin is clean. We send a picture of the filter to each customer so they can see what type of condition the cabin air filter is in.

If a dealership service department or repair shop recommends you get a new cabin air filter, ask to see the current one. Depending on how long the air filter has been in service, you might be shocked at what you see: a filter clogged with leaves, twigs, insects, pollen, soot and grime that literally covers the entire surface that comes in contact with incoming air can all be a problem for the cabin inside your vehicle. You’ll know it’s time for a cabin air filter replacement for your car.
