Cabin Air Filter Replacement Cost
Slide open the glove-box access panel and swap the filter. The highest-markup item at most quick-lube shops.
What this repair is
The cabin air filter cleans the air coming through your heating and air conditioning system, trapping pollen, dust, and exhaust fumes before they enter the passenger compartment. It should be replaced every 15,000 to 25,000 miles, or at least once a year.

When to call a shop instead
Never worth paying for. The filter is usually behind the glove box and takes five minutes to swap with no tools. Quick-lube shops charge $55–$85 for a $25 filter — the highest markup of any common service.
Is your quote fair?
Never pay $85 for a cabin air filter swap. The part costs $20–$30 and takes 5 minutes behind the glove box — the highest-markup service at quick-lube shops.
How to budget for this
Budget about $25 for a DIY filter swap or $70–$85 at a shop, once a year for one cabin air filter replacement.
Cabin Air Filter Replacement FAQ
How often should I change my cabin air filter?
Every 15,000 to 25,000 miles or once a year, whichever comes first. If you drive in heavy traffic, construction zones, or pollen-heavy areas, replace it more often.
Where is the cabin air filter located?
On most cars it's behind the glove box — open the glove box, squeeze the sides to drop it down, and the filter tray is right there. On some vehicles it's under the hood near the windshield wipers.
Can a dirty cabin air filter affect my A/C?
Yes. A clogged filter restricts airflow, making the blower work harder and reducing cooling and defrosting performance. It also strains the blower motor and can cause premature failure.
