The cabin air filter in a Mazda CX-5 is located behind the glove box on the passenger side. Access is gained by opening and lowering the glove box to reveal the filter housing that can be opened to replace the filter.
Location and access
In most CX-5 generations, the filter sits in a housing behind the passenger-side glove box. You’ll need to lower the glove box to expose the cover, then remove the filter once you’ve released the housing. This location is standard across most trims, though minor differences can occur by year or market; consult your owner's manual for your specific model.
What you’ll need
Gather a few basic items before you start so you can complete the replacement without interruption.
- A fresh cabin air filter (check for the correct size/part number for your CX-5)
- Optional: a small flat-head screwdriver or a trim tool to release clips
- Clean rag to wipe away dust
- Gloves to keep your hands clean
Having these on hand helps ensure a smooth replacement and prevents accidental damage to the glove box or filter housing.
Replacement steps
Follow these steps in order to remove the old filter and install a new one. The exact fasteners may vary by year or trim; look for screws or a snap-in panel with tabs.
- Park the car, set the parking brake, and turn off the ignition.
- Open the passenger-side glove box and let it hang down; if your model has a damper, gently disconnect or release the arm so the box stays open.
- Locate the cabin air filter housing behind the glove box; release the cover by pressing tabs or removing screws as needed.
- Carefully remove the old filter, taking note of the orientation and the direction of airflow indicated by the arrows on the filter.
- Insert the new filter with the arrows pointing in the same direction as indicated by the housing; ensure it sits flat and fully seated.
- Reinstall the housing cover, reattach the glove box damper or arm, and close the glove box.
After replacement, test the HVAC system by turning on the ignition and running the fan on different speeds to ensure air flows properly and the path is clear.
Maintenance tips
Regular replacement keeps odors down and improves HVAC performance, especially in dusty or pollen-heavy areas. Use the filter recommended by Mazda for your CX-5 model year, and consider replacing more frequently in demanding environments.
Summary
For most Mazda CX-5 models, the cabin air filter sits behind the passenger-side glove box. Access it by lowering the glove box, releasing a cover on the filter housing, and swapping in a new filter with the correct orientation. Replacement is typically recommended every 15,000 miles or 12 months, whichever comes first, with more frequent changes in dusty or high-pollen conditions.
