The Functions of a Cabin Air Filter

Every driver is aware of the engine air filter which usually gets checked on with every oil change. The engine air filter keeps dirt and dust out of the engine components and helps your engine last as long as it can. The cabin air filter does much the same job as the name implies to your automobile’s cabin. The cabin air filter keeps out dust, pollen, and other irregularities to keep you and your passengers free of any foul odors or possible allergens. Keeping your cabin air filter in good working order is especially prudent in dusty environments and cities with poor air quality.

Cabin Air Filter Replacement – Drawbacks for Poor Maintenance

For those out there who disregard the cabin air filter as a minor part that doesn’t need to be replaced, there are significant drawbacks to this thought process. Keeping a cabin air filter long after its expiration date can wreak havoc on your vehicle’s HVAC system. Your HVAC system will work harder to keep your cabin temperature at a comfortable level due to the introduction of dust and other particles into the system. This can shorten the life of your HVAC system over time and also slowly deplete the freon in your system due to increased use. You’ll also introduce rancid smells and other undesirable odors into the cabin with a worn-out cabin air filter, so replacement is a must!

When Should You Replace Your Volkswagen Cabin Air Filter?

Cabin air filters should be inspected every six months or so or every other oil change to see the condition that it’s in. Most automobile manufacturers recommend that the cabin air filter should be replaced every 12,000 miles or replace it annually if you don’t drive that much. This replacement schedule should be ramped up even more if you live in a dusty environment such as the dry and arid conditions in parts of Southern California and Nevada. These environments require you to monitor the cabin air filter with every oil change and change it every 5,000 miles or every other oil change. Keeping on top of your cabin air filter will keep your cabin comfortable to drive in and also keep your HVAC system working at its best.
