The engine air filter sits inside a black plastic air box in the engine bay, usually on the passenger side toward the front, while the cabin air filter is located inside the vehicle behind the glove box on the passenger side.
Engine air filter location
The Honda Odyssey uses a long-running V6 engine, and the engine air filter is housed in a rectangular air box in the engine compartment. In most Odyssey variants, this housing sits on the passenger side of the engine bay and is connected to the intake duct that leads to the throttle body. You’ll typically see a black plastic box with a removable lid secured by clips or screws. If you’re unsure about your specific year, the owner’s manual or a quick online model-year guide can confirm exact placement.
Notes on model-year differences
While the general arrangement is consistent, the exact shape and fasteners can vary slightly between generations. The lid is usually clipped or bolted on and can be pried up with a flat tool or by hand. The air filter itself is a rectangular or square element that sits inside the housing and is oriented so that air flows through it in the direction indicated by arrows on the filter.
To locate and replace the engine air filter, follow these steps:
- Open the hood and look for a large black plastic box labeled "Air" or "Air Filter" in the engine bay, typically on the passenger side front area.
- Release the clips or remove the screws securing the lid, then lift the lid away from the housing.
- Take out the old filter element and inspect the inside of the housing for debris or signs of dirt.
- Install a new filter with the correct orientation (match the arrows on the filter to the airflow direction), then reseat the lid and fasten the clips or screws firmly.
- Reattach the intake hose if you had to disconnect it, and close the hood. Run the engine briefly to ensure there are no leaks or misfits.
Replacing the engine air filter is a routine maintenance task that can improve airflow, performance, and fuel efficiency. If you notice reduced power or strange engine noises, it might be time to inspect or replace the filter.
Cabin air filter location
The cabin air filter in most Honda Odyssey models is located inside the vehicle, behind the glove box on the passenger side. Access to the filter is gained by lowering or removing the glove box, after which you’ll see a cover that protects the filter. The cabin filter cleaner improves interior air quality by filtering dust, pollen, and odors before air passes through the HVAC system.
Cabin filter access steps
To access and replace the cabin air filter, follow these steps:
- Open the glove box and clear its contents. If your model uses dampers or stops, depress the sides to lower the glove box fully or remove the limiting arm.
- Carefully lower the glove box until you can see the filter access panel behind it.
- Remove the filter cover or panel, then slide out the old cabin filter.
- Install the new cabin filter with the correct orientation (arrows on the filter point in the direction of airflow).
- Reattach the cover and the glove box, then test the HVAC by turning on the fan to verify airflow.
Cabin filter replacement intervals vary by driving conditions and year, but a common guideline is every 15,000 to 30,000 miles or per the owner’s manual. Replacing the cabin filter helps maintain interior air quality and HVAC efficiency.
Summary
In the Honda Odyssey, there are two filters to consider: the engine air filter, located in a black plastic air box in the engine bay (generally on the passenger side toward the front), and the cabin air filter, located behind the glove box on the passenger side. Both are designed for relatively easy replacement with basic tools and care. Regular checks and timely replacements can improve engine performance, fuel economy, and interior air quality.
