In most cars, the cabin air filter is located behind the glove box. You can remove it yourself by detaching the glove box from the fasteners that hold it in place. If this is the case, your owner’s manual should provide instructions on how to remove the glove box. However, if your cabin air filter is located under the dashboard or under the hood, it may not be easy to access.
If you do plan to change it yourself, consider buying a replacement filter at an auto parts store or website to save money. Car dealers can charge up to $50 or more per filter. The average cost of a cabin air filter is between $15 and $25. The labor cost to replace the filter is $36 to $46, but you may end up paying more if it’s hard to get to. Parts for higher-end cars are more expensive and may only be available through the dealer.
If you have your vehicle serviced at a repair shop or dealership, the technician may recommend changing the cabin air filter. Ask to see your current filter before you agree. You may be surprised to see your filter covered in soot, dust, leaves, twigs, and other grime, which confirms the importance of replacement service. However, if your car’s air filter is clean and free of debris, you can probably wait.
If you don’t replace a dirty, clogged filter, it will affect the efficiency of your car’s heating and cooling system. Inefficiency can lead to other problems, including loss of air volume, cabin odors, or premature failure of HVAC components. Simply replacing a dirty filter can greatly improve your car’s air quality.
Other Steps to Protect Your Vehicle
There are other things you can do to maintain air quality and prevent other allergens from taking up residence in your car:
Vacuum upholstery, carpets, and rugs regularly.
Wipe down surfaces, including door panels, steering wheels, consoles, and dashboards.
Check the weatherstripping on doors and windows for a good seal.
Clean up spills immediately to prevent mold growth.
