In a 2020 Honda CR-V, the cabin air filter (often called the pollen filter) is located behind the glove box on the passenger side. Access it by opening the glove box and lowering it to reveal the filter housing.
Replacing the cabin air filter helps maintain clean air inside the cabin and ensures the HVAC system runs efficiently. The filter is housed in a small rectangular slot behind the glove box; below are steps to locate, inspect, and replace it, plus maintenance tips.
Location and access
The cabin air filter sits inside a dedicated housing behind the glove box on the passenger side of the instrument panel. In most 2020 CR-V models, you do not need to remove the entire dash—just open the glove box and drop it down to expose the housing and the filter cover. A flashlight can help you see the housing and tabs.
What you’ll need
Typically no tools are required. You may want a flashlight, and in some cases a small flathead screwdriver or tweezers to lift stubborn cover tabs.
Before you start: ensure the vehicle is off and the glove box is clear of contents. Have a replacement cabin air filter ready that matches the CR-V 2020’s filter size and type (standard cabin/pollen filter used by Honda for that year).
- Open the glove box and allow it to hang down by squeezing the sides to release the stops or by removing the glove box damper if equipped.
- Look up at the top of the glove box area for the filter housing cover and slide or release the cover’s tabs.
- Remove the filter cover and take out the old cabin air filter. Note the orientation of the filter (the arrow on the filter should point toward the HVAC blower).
- Wipe or lightly clean the filter housing interior if there’s dust or debris.
- Insert the new filter in the same orientation as the old one, ensuring it sits flat in the housing.
- Reattach the filter cover, close the glove box, and push it back into its original position.
- Start the vehicle and run the HVAC briefly to confirm smooth airflow and no unusual noises.
With the new filter in place, reassemble the glove box and verify proper operation of the HVAC system.
Maintenance interval and care
Keeping the cabin filter fresh helps maintain air quality and HVAC efficiency. Here are guidelines and signs to watch for.
- Replacement interval: about every 12–15 months or 12,000–15,000 miles, whichever comes first. If you drive in dusty or urban environments, consider shortening the interval.
- Signs of a worn or dirty filter: reduced airflow, unpleasant odors, increased allergy symptoms, or foggy windows due to poor cabin filtration.
- Filter type considerations: some CR-V 2020 models use a standard cabin filter, while higher trims or optional packages may include a carbon-activated or dual-layer filter for odors; check your owner’s manual for the exact part designation.
- Post-replacement check: after installing a new filter, ensure the housing cover is securely seated and the glove box closes smoothly.
Regular inspections help you catch a clogged filter before it affects airflow or HVAC performance.
Summary
The cabin air filter in the 2020 Honda CR-V is located behind the passenger-side glove box. Access it by lowering the glove box, removing the filter cover, and replacing the filter with the correct orientation. Routine replacement—typically every 12–15 months or 12,000–15,000 miles (more often in dusty areas)—keeps cabin air clean and the HVAC system functioning efficiently.
