Yes. The 2020 Honda Accord Hybrid uses two accessible filters you can replace yourself: the engine air filter and the cabin air filter. Plan about 15–25 minutes per filter, and use OEM or equivalent aftermarket replacements. Typical service intervals are around 30,000 miles for the engine air filter and 15,000 miles for the cabin air filter, or as specified in your owner's manual.
Before you begin, gather the tools and replacement parts you’ll need to complete both filter changes smoothly.
- Engine air filter (new)
- Cabin air filter (new)
- Basic tools: screwdriver (if required by your trim), pliers or a small clip tool, clean rag
- Gloves to keep your hands clean
- Optional: flashlight, small vacuum or compressed air for cleaning the housings
Having these items ready will help you complete the replacements quickly and safely.
Engine air filter replacement
The engine air filter protects the engine from dust and debris. Replacing it when it’s dirty helps maintain performance and fuel efficiency. For normal driving, plan roughly every 30,000 miles, though dusty or harsh conditions may require more frequent changes.
Location and access
The engine air filter housing is in the engine bay, typically on the passenger side near the front. It is a rectangular plastic box with a removable lid secured by clips or bolts. Access the clips and lift the lid off to expose the filter.
Replacement steps
Follow these steps to replace the engine air filter.
- Park on a flat surface, engage the parking brake, and switch the ignition off. If you’re concerned about electrical components, you can disconnect the negative battery terminal, though it’s optional for this task.
- Open the hood and locate the engine air filter housing.
- Release the housing clips or remove bolts and lift the lid away. Note how the old filter sits inside the housing.
- Take out the old filter and inspect the housing for dust or debris. Wipe clean if needed.
- Insert the new filter, ensuring it seats properly and matches the orientation of the old filter. A proper seal is important to prevent unfiltered air from entering.
- Reattach the housing lid and secure the clips or bolts firmly. If you detached any hoses or sensors, reconnect them.
- Close the hood, start the engine, and run it for about a minute to verify normal operation and no unusual sounds.
When installed correctly, the engine will breathe more easily and you may notice improved throttle response and economy.
Cabin air filter replacement
The cabin air filter cleans air entering the passenger compartment via the HVAC system. Replacing it can improve airflow and reduce odors, especially in dusty environments. Many Accord Hybrids use a cabin filter replacement interval around 15,000 miles, but consult your manual for the exact specification for your trim and climate.
Location and access
In the 2020 Accord Hybrid, the cabin filter is behind the glove box. Access typically requires lowering or removing the glove box and then removing a cover that hides the filter.
Replacement steps
Prepare for the cabin filter replacement with these steps.
- Park on a level surface and turn off the vehicle. Open the glove box and support it so it doesn’t drop.
- Gently disconnect the glove box damper or stops to allow the box to drop further for access.
- Remove the cabin filter cover by sliding or unclipping it.
- Take out the old cabin filter and wipe out any debris from the housing.
- Install the new cabin filter with the correct orientation, following the airflow arrows on the filter.
- Reattach the filter cover and restore the glove box to its original position. Ensure the damper/stops are seated properly.
- Close the glove box and turn on the HVAC to verify that air is flowing normally from the vents.
Replacing the cabin filter can yield crisper fan performance and better interior air quality, particularly for allergy sufferers or in high-pollen months.
Maintenance tips and reminders
To keep performance optimal, set reminders for filter checks and replacements. Always use filters that meet or exceed OEM specifications, and avoid reusing old filters. If you drive in very dusty or polluted areas, consider more frequent replacements or a higher-grade filter.
When to replace sooner
If you notice reduced airflow from the HVAC system, musty or unusual odors, or increased cabin dust, inspect and potentially replace the cabin filter sooner. Engine performance changes or a decrease in fuel economy can also indicate a filter that needs attention.
Summary
The 2020 Honda Accord Hybrid makes it straightforward to change both the engine air filter and the cabin air filter. By following the outlined steps—locating the housings, removing the old filters, installing new ones correctly, and resealing—the car can maintain better engine efficiency and cleaner interior air. Always refer to the owner’s manual for model-specific guidance and replacement intervals, and use filters that meet Honda’s specifications for best results.
