Cabin Filter: What? Where? When?

Your vehicle's "Cabin Air Filter" often lives in the shadows of the more popular air, gas and oil filters. In fact, many car car owners don’t even know they exist. But they do!

What is a cabin air filter?
The primary purpose of cabin air filters is to filter out pollutants such as dust, pollens and mold from entering the vehicle’s cabin (interior), through the AC ductwork. Besides preventing allergy problems, cabin filters help to improve the quality of air you breath. Over time, a cabin filter may become clogged and restricted with debris, thus reducing the velocity of air delivered from your AC vents. If you feel that the air coming from your AC vents is not as strong as it used to be, you may have a restricted cabin filter.

Where is it located?
Most vehicles since 2000 usually have some type of cabin filter located either behind the glove box or under the hood.

When to replace?
Rule of thumb is to replace the cabin air filter every 15,000 to 25,000 miles or once a year, depending on the area you travel in. If you travel by heavy construction sites or on dirt roads on a daily basis, you may want to check your cabin filter more frequently, every 8000 to 10,000 miles or twice a year. Ask Jim if your vehicle has a cabin filter and if it needs replacing.

What brand filter to use?
Any of the top-name filter makers would be a good choice: Wix, Purolator, Fram just to name a few. Any of these should be more than efficient in filtering out pollutants.
