Cabin Air Filter Service Video

The cabin air filter cleans the outside air before your heating and AC system blows it into the car. It catches pollen, dust, and road grime so you and your passengers are not breathing them in.

In this video, you will see where the filter housing sits on a typical vehicle and how the filter comes out. It also puts a used filter beside a new one, so you can see how much it collects over months of driving.

Weak airflow from the vents, even with the fan on high, is the most common sign of a clogged filter. A musty smell when the heat or AC first turns on is another, and some drivers notice the windows take longer to defog.

At Spectra Auto Services, the cabin air filter is checked during the multi-point inspection that comes with every oil change. You get a DVI photo of the filter before deciding on a replacement. The full service is covered by our preventive maintenance service.

A dirty cabin filter worsens allergies during Frederick's heavy spring pollen season. Drivers from Urbana and Walkersville often have us check it in early spring, before the trees bloom.

If your vents feel weak or smell musty, call Spectra Auto Services at (301) 695-5990, or book auto repair in Frederick to have the filter checked.
