The Honda Odyssey has two air filters: one engine air filter and one cabin air filter.
Across most U.S.-spec Odysseys, these two filters protect the engine’s intake and the cabin air that occupants breathe. This article outlines what each filter does, where to find it, and typical replacement intervals.
Two filters, two roles
The Odyssey relies on a straightforward filtration setup: one filter for the engine’s air intake and one filter that cleans the air entering the passenger cabin. Here are the details for each.
Note that replacement intervals can vary by year, trim, and driving conditions. Always consult the owner’s manual or a Honda dealer for exact guidance.
Engine air filter — cleans air entering the engine intake. Location: engine compartment, usually on the side of the air intake box. Typical replacement interval: about every 30,000 miles (48,000 km) under normal driving; dusty or severe conditions may require earlier changes. Signs of a worn filter include reduced power, lower fuel economy, and rough idle.
Cabin air filter — cleans air entering the cabin through the HVAC system. Location: behind or near the glove box (varies by model year). Typical replacement interval: about every 15,000 miles (24,000 km) or every 12–24 months, depending on environment. Symptoms of a clogged filter include reduced airflow, musty odors, or increased allergy symptoms.
Regular maintenance of both filters helps maintain engine performance and cabin comfort. Check your owner’s manual for the exact replacement schedule for your specific Odyssey year and trim, and use the correct filter type (standard or activated carbon) as recommended.
Filter specifics
Engine air filter
Location: The engine air filter sits in the air intake box in the engine bay, typically on the driver's side. Access usually requires removing a clip-on cover and a few fasteners. Replacement steps are straightforward but take care not to let debris fall into the intake. Replacing at the recommended interval helps prevent dirt from entering the engine and preserves performance.
Cabin air filter
Location: The cabin filter is typically located behind the glove box or under the dashboard, depending on model year. Access often involves lowering or removing part of the glove box. Replace with a new filter by inserting it in the correct orientation and resecuring the cover. Using a cabin filter with activated carbon can help with odors, but check compatibility with your vehicle.
Summary
In short, a Honda Odyssey has two air filters—one engine air filter and one cabin air filter. Exact locations and replacement intervals vary by year and market, so follow the owner's manual for precise guidance. Keeping both filters fresh helps maintain engine efficiency and cabin air quality.
