The cabin air filter on a 2018 Honda CR-V LX is located behind the glove box on the passenger side. To replace it, lower the glove box and remove a small cover to access the filter.
Location and what to expect
In the 2018 CR-V LX, the cabin air filter sits in a rectangular housing tucked behind the passenger-side glove box. Access is gained by opening the glove box, letting it drop down, and then removing a panel or cover that protects the filter. The exact attachment method can vary slightly by vehicle, but clips or small screws are commonly used to secure the cover.
How to access and replace the cabin air filter
Follow these steps to access and swap the cabin air filter in the 2018 CR-V LX. The process is straightforward and does not require specialized tools in most cases:
- Park the vehicle on a level surface and turn off the engine. Open the glove box and remove any contents.
- Squeeze the sides of the glove box to release its stops and allow the box to drop down. If your model includes a glove box damper, disconnect or move it as needed to lower the box fully.
- Look for a rectangular filter housing behind the glove box. The cover is held in place by clips or a couple of small screws.
- Remove the filter cover and lift out the old cabin air filter. Note the orientation of the filter (airflow arrows should point toward the rear of the vehicle).
- Insert the new filter with the arrows pointing the same direction as the old one, ensuring it sits flat in the housing.
- Reattach the filter cover, lift the glove box back into place, and reattach the damper or stops as needed. Close the glove box.
With the new filter installed and everything secured, run the HVAC briefly to confirm proper airflow and check for any unusual odors.
Maintenance notes and tips
Most owners replace the cabin air filter every 12 months or 12,000 miles (whichever comes first), though heavier use or dusty environments may warrant more frequent changes. Always handle the filter by the edges and avoid touching the pleats, and make sure the arrow on the filter points in the direction of airflow when reinstalling.
