What is that smell? Does your car have an odor that never goes away? Air fresheners seem useless and makes matters worse? The car still smells like smoke after having the interior detailed? The cabin air filter may be the culprit.

The cabin filter traps dirt, pollen, moisture, and debris. This filter is different from the engine air filter. It cleans outside air coming into the vehicle passenger cockpit through the vents. In many cases, it is located behind the glove box.

Over time, it becomes clogged and grows bacteria. Cabin air filters are made of paper, cotton or other porous material. A dirty cabin filter will produce a bad smell in the heating and cooling system (HVAC). It can aggravate allergies and asthma.

According to some experts, the cabin filter should be replaced between 12,000-15,000 miles. Others recommend 25,000 – 30,000 miles. The best recommendation is check with your vehicle manufacturer.

Another option is to buy a reusable filter and clean it at least once a year.
