What Are Cabin Air Filters and How Do They Work?

How to Replace Cabin Air Filters

We make replacing your cabin air filters as easy as 1-2-3, and replacing your filter is much easier than you think! Most cabin air filters are located behind the glove box, though some are under the hood or dashboard, and can be easily installed in 15 minutes or less. Follow these steps:

• Check Your Manual – Locate your cabin air filter

• Access the Filter – Open the glove box or remove the necessary panels

• Remove the Old Filter – Pull out the dirty filter. Don’t be surprised if it’s nastier than a fast-food wrapper left in the sun 😂

• Insert the New Filter – Make sure it’s oriented correctly (look for airflow direction arrows)

• Close It Up – Secure everything back in place

How Often Should I Replace My Cabin Air Filters?

Here’s the deal: most manufacturers recommend swapping out your cabin air filter every 12,000 to 15,000 miles, or every 12 months. Above all recommendations, you should always change your cabin air filters according to your vehicle’s manufacturer warranty. If you drive on dirt roads, live in a high-pollen area, or enjoy off-roading adventures, you might need to replace it more often. Ignoring it? That’s like wearing the same pair of socks for a year—gross, right?

Benefits of Changing Your Car Filters Regularly

• Improved fuel efficiency and engine performance

• Enhanced air quality inside the vehicle

• Prevention of costly repairs by maintaining engine health

• Better environmental impact through reduced emissions

• Increased lifespan of the vehicle

How a Dirty Cabin Air Filter Impacts Your Vehicle’s Performance

A clogged filter doesn’t just mess with your air quality. It can restrict airflow to your HVAC system, making it work harder. The result? Reduced efficiency, a foggy windshield that refuses to clear, and a cabin that smells like a damp gym bag. Worst of all, you’re putting extra strain on your vehicle, which could lead to bigger problems and costly repairs down the road.
