The cabin air filter in a 2008 Honda Odyssey is located behind the glove box on the passenger side. Access it by lowering the glove box, releasing the housing cover, and swapping in a fresh filter. Regular replacement helps keep interior air clean and the HVAC system performing well.
Where to locate the filter
The filter sits behind the glove box on the passenger side. You access it by lowering the glove box and exposing a rectangular filter housing with a removable cover labeled Pollen Filter.
What the filter housing looks like
The filter is housed in a small rectangular panel recessed into the dash area behind the glove box. The cover is typically held on by a couple of tabs that you press to release.
- Open the glove box and remove its contents.
- Gently press in on the sides of the glove box to release the stops and let the box drop down.
- Look up into the dash area on the passenger side to locate the rectangular filter housing and its cover.
- Release the cover by pressing the tabs or pulling on the edge, then pull out the old filter.
With the old filter removed, you can proceed to insert a new one. Handle the housing carefully to avoid letting debris fall into the HVAC system.
Installing a new cabin air filter
Make sure you have the correct replacement for your 2008 Odyssey. Use a genuine Honda filter or an aftermarket filter labeled compatible with 2005–2010 Odysseys, and verify the orientation before installation.
Orientation and seating
Orient the new filter so the arrows on the filter face toward the cabin (in the direction of airflow into the passenger compartment). Insert it into the housing until it sits evenly and the edges align with the housing.
- Remove the new filter from its packaging and check the orientation arrows.
- Insert the filter into the housing with the arrows pointing toward the cabin (the direction of airflow into the passenger area).
- Push the filter in until it sits evenly and the edges align with the housing.
- Reattach the housing cover by snapping the tabs back into place.
- Raise the glove box and ensure the damper and hinges are seated properly, then return items to the glove box.
Verify that the housing is securely closed and that the glove box closes normally without squeaks or snagging.
Summary
For a 2008 Honda Odyssey, the cabin air filter 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. Regular replacement (approximately once a year or more often in dusty conditions) helps maintain air quality and HVAC efficiency.
