Replacing the cabin air filter is a quick DIY task that you can complete in about 10-15 minutes by accessing the filter housing behind the glove box on the passenger side and swapping in a fresh filter.
In this guide, we detail where the filter sits, what you’ll need, and a clear step-by-step process for most 2019-and-later Honda Passport models. Designs can vary by year and trim, so consult your owner’s manual for year-specific instructions and part numbers.
What you’ll need
Gather these items before you start to make the replacement smooth and clean.
- New cabin air filter compatible with Honda Passport (check year and trim). Opt for a genuine Honda part or a reputable aftermarket alternative.
- Clean cloth or a small vacuum for cleaning the housing.
- Optional: a flashlight to illuminate the filter housing.
- Optional: a small screwdriver or trim removal tool if any clips or trim pieces need a gentle pry.
- Gloves to keep your hands clean.
With the correct parts and tools on hand, you’re ready to access the filter assembly and swap in a fresh unit.
Step-by-step replacement
Follow these steps to access the cabin air filter, replace it, and restore normal HVAC operation.
- Park on a flat surface, engage the parking brake, and turn off the engine. You can set the climate control to off for simplicity.
- Open the glove box and remove its contents to create room to work.
- Gently squeeze the sides of the glove box to release the stops and let the box drop down. In some Passport trims, you may need to ease a damping cap or hinge to allow full access.
- Inside the housing, locate and remove the cabin air filter cover. It’s typically held in place by clips or a simple latch.
- Carefully pull out the old filter and note its orientation. Install the new filter with the arrows indicating the direction of airflow as printed on the filter.
- Wipe the housing with a clean cloth and vacuum any loose debris to ensure a good seal for the new filter.
- Insert the new filter until it sits flat and fully seated in the housing. Reattach the cover and secure the clips or latch.
- Raise the glove box back into place and ensure it latches securely.
- Start the vehicle and run the HVAC on fresh air to verify air is flowing properly through the vents. If airflow seems weak, recheck the filter seating and orientation.
Replacing the cabin air filter is a straightforward maintenance task, but it helps to do it promptly if you notice reduced airflow, musty odors, or increased pollen exposure inside the cabin.
Orientation and tips
The filter has arrows that indicate the direction of airflow. Install the new filter so those arrows match the path air takes through the housing (air typically moves from outside the cabin into the HVAC core). If the fit feels tight or the cover won’t close, recheck that the filter is fully inserted and properly oriented.
In terms of timing, Honda Passport cabin air filter replacement is generally recommended every 12-24 months or roughly 12,000-24,000 miles, depending on driving conditions and environment. In dusty or urban areas, or if you have allergies, consider replacing more frequently. Always defer to your owner’s manual or dealer for the official interval and part numbers for your exact year and trim.
Summary
Accessing the cabin air filter on a Honda Passport is a straightforward DIY repair. By locating the filter behind the passenger-side glove box, replacing the filter with proper orientation, and reseating the housing, you can maintain clean air in the cabin with minimal effort.
