The cabin air filter in a Honda Passport sits behind the glove box and can be replaced in about 10 minutes using basic steps.
Where to locate the cabin filter
The filter is housed behind the passenger-side glove box. To access it, you typically drop the glove box by releasing the side tabs or the glove box damper, which exposes the rectangular filter housing.
What you’ll need
Before you start, gather these items so the replacement goes smoothly.
- Replacement cabin air filter compatible with the Honda Passport (activated carbon filters help with odors)
- Flathead screwdriver or trim tool (optional, for stubborn clips)
- Clean rag or small vacuum for cleaning the housing
- Gloves (optional) to keep hands clean
Using the right filter and a clean housing helps ensure proper filtration of dust, pollen, and odors, and activated carbon variants can improve odor control.
Step-by-step replacement
Follow these steps in order to replace the filter.
- Park the vehicle, turn off the engine, and engage the parking brake. Make sure the climate control is off before you begin.
- Empty the glove box to give yourself space to work.
- Gently squeeze the sides of the glove box to release its stops and lower the box, or detach the glove box damper if your model requires it to access the filter housing.
- Locate the rectangular cabin filter housing behind the opened glove box and remove the cover by unclipping or sliding it out.
- Slide the old filter straight out from the housing. Note the orientation of the filter (the airflow arrows should point toward the rear of the vehicle).
- Vacuum or wipe any dust from the housing to prepare for the new filter.
- Insert the new filter firmly into the housing in the same orientation as the old one, with the arrows pointing to the rear of the vehicle.
- Reattach the filter cover securely and close the glove box, ensuring it latches properly.
- Start the engine and run the A/C for a few minutes to confirm normal airflow and check for any unusual odors.
With the new filter in place, you should notice improved airflow and a reduction in dust and pollen entering the cabin.
Tips and maintenance
Keep these tips in mind to maximize filter life and cabin air quality.
- Replace the cabin air filter every 12–15 months or about every 15,000 miles, whichever comes first. In dusty or high-pollen environments, consider more frequent replacements.
- Opt for an activated carbon filter if you notice odors or drive in polluted areas.
- Always confirm the filter orientation, with the airflow arrows pointing toward the rear of the vehicle, when installing.
- Dispose of the old filter properly and store the new filter in its packaging until you’re ready to install it.
Regular maintenance of the cabin air filter helps maintain HVAC efficiency and cabin cleanliness over time.
Summary
In a Honda Passport, the cabin filter sits behind the glove box. Access the housing, remove the old filter, insert a correctly oriented new filter, and reassemble. Following the recommended replacement intervals keeps cabin air clean and ensures optimal HVAC performance.
