Of all the different types of routine car maintenance, one of the easiest to overlook is replacing the cabin air filter. However, cabin filters play a crucial role in the safety and reliability of your vehicle. What are cabin air filters and how often should you replace yours?

Cabin Air Filters 101

Most automobiles have various filters for different purposes. You’ve very likely had to replace your engine air filter and/or the oil filter a hand full of times throughout the life of your vehicle. But what about the cabin air filters? You should be sure to replace these too because they can protect your own health and the health of your vehicle.

There are several types of pollutants in the air, especially on crowded roadways and gravel roads. Cabin air filters keeps those pollutants, as well as dirt and debris, from entering your cabin though your AC system. Not only does this benefit drivers and passengers by keeping allergens and other respiratory concerns at bay, it also benefits the automobile itself. Keeping dirt and debris out of your AC system is a sure way to ensure it continues to function well over the long haul.

Replacing Cabin Air Filters

Replacement time for cabin air filters vary based on manufacturer recommendations.  Many manufacturers recommend replacing the filter every 12,000 miles (this ends up being about once a year for the average driver). Ultimately, manufacturers offer a large range of recommendations, but the quality of the air and roads around you will really be the determining factor in air filter replacement time.

There are signs of wear you can use to gauge whether or not it’s time for a replacement. If you notice several black spots on the filter itself, this is a good sign that it’s time to change the filter. Naturally, your mechanic will be happy to help you gauge whether or not a replacement would be best for you. A good rule of thumb, however, is to make sure you change your air filter roughly every year. This low-cost replacement will keep dirty air out of your cabin, lungs and AC system.
