What's my cabin air filter and when do I need to replace it?

What is a cabin air filter?

A cabin air filter is a fibrous device that catches dust, bacteria, and other kinds of air pollution particles and keeps them from getting into your car's cabin through your air conditioning or heating systems. This results in a cleaner, healthier driving environment for you and your passengers as you drive around Stamford or anywhere you drive.

Why do I need to replace my cabin air filter?

Over time, your vehicle's cabin air filter gets more and more filthy as it traps pollutants and keeps them from getting into your cabin. The dirtier your filter the less effective it is. Replacing it regularly helps to ensure that the contaminants in the air outside stay outside.

How often should I replace a cabin air filter?

We recommend replacing your cabin air filter every 15,000 miles or so -- around every other service interval. This is a general recommendation for most vehicle, but your owner's manual or a technician at Riley Mazda can give you specifics for your specific model. 

Your driving environment may also influence the frequency of necessary changes. For example, if you spend a lot of time driving on dusty roads near Danbury, your cabin air filter may get dirtier faster. 

If your car's cabin starts to smell bad, and it can't be attributed to stinky feet, then there is a good chance that you need a new cabin air filter.
