The short answer: you can replace both the engine air filter and the cabin (HVAC) air filter yourself in roughly 10–20 minutes using basic tools. This guide walks you through locating, removing, and installing fresh filters on a 2022 Honda Accord, with tips to ensure proper fit and orientation.
What you’ll need to know before you start
Before you begin, identify which filters you’re replacing. The engine air filter sits in a rectangular housing in the engine bay and the cabin air filter sits behind the glove box. Most models require only basic hand tools or none at all, but having a clean workspace and good lighting helps. Always install filters with the airflow arrows pointing toward the engine for the engine filter and toward the HVAC system for the cabin filter.
Engine air filter replacement
Before you start, understand what you’re about to do: replace the engine air filter to keep dirt out of the intake and protect engine performance. This section covers the common steps on the 2022 Accord.
What to look for before replacing
Signs that you may need to replace the engine air filter include a visibly dirty filter, reduced engine performance, or a drop in fuel efficiency. If you drive in dusty or harsh environments, inspect more frequently.
- Park the car on a level surface, turn off the engine, and set the parking brake. Open the hood and locate the engine air filter housing (a rectangular black plastic box, usually toward the front/side of the engine bay).
- Release the clips or screws securing the housing lid. In most trims, you’ll simply lift the lid or twist the fasteners to open.
- Lift off the lid and carefully remove the old filter. Take note of how it sits in the housing so you can install the new one the same way.
- Wipe the inside of the housing with a clean cloth to remove any dust or debris. Do not spray liquids into the housing.
- Insert the new engine air filter, ensuring it seats firmly in place. If there are airflow arrows on the filter, point them toward the engine.
- Reinstall the housing lid and secure all clips or screws tightly. Ensure there are no gaps where unfiltered air could enter.
- Close the hood and start the engine to confirm normal operation and listen for any unusual sounds indicating a loose fit.
Regular replacement helps maintain engine efficiency and performance. Keep the new filter in its packaging until you’re ready to install to avoid contamination.
Cabin air filter replacement
Before you start, know that the cabin air filter cleans outside air before it enters the cabin through the HVAC system. Replacing it improves airflow and helps control odors inside the car. This section outlines the typical steps for the 2022 Accord.
What to look for before replacing
Look for signs like reduced airflow from the vents, musty odors, or increased dust in the cabin. If you notice any persistent smells after replacing the filter, check for moisture or mold behind the glove box.
- Open the glove box and remove its contents. If your model has dampers or stoppers, gently release or unhook them so the glove box can drop down.
- Lower the glove box to access the cabin filter cover located on the back wall of the glove box area.
- Remove the cabin filter cover by releasing the clips or screws, whichever is used on your trim, then take out the old filter.
- Inspect the old filter for debris. Note the orientation of the filter so you can install the new one the same way.
- Insert the new cabin filter with the arrows pointing toward the HVAC system (in the direction of airflow into the cabin). Ensure a snug fit around all edges.
- Reattach the cabin filter cover and secure the glove box by re-engaging any dampers or stops. Return the contents to the glove box.
- Run the HVAC system for a few minutes on fresh air to confirm proper airflow and listen for any rattle from a loose filter.
Cabin filter replacements typically take about 5–10 minutes and can be done without special tools. Replacing the filter helps keep interior air clean and can improve heating and cooling efficiency.
Maintenance and safety tips
- Always ensure the engine is off and the vehicle is parked on a level surface before starting any work.
- Wear gloves to protect your hands from sharp edges in the engine bay and to keep them clean.
- Dispose of old filters according to local guidelines; many automotive stores offer recycling options.
- Keep a spare filter on hand if you drive in particularly dusty conditions; check both filters at the intervals recommended in your owner's manual.
Properly maintaining both filters helps protect the engine and improve cabin comfort. If you encounter a stubborn fastener, a damaged housing, or you’re unsure about fitment, consult a professional mechanic.
Summary
Replacing the engine air filter and the cabin air filter on a 2022 Honda Accord is a straightforward, do-it-yourself maintenance task that typically takes 10–20 minutes total. With the right filters and correct orientation, you’ll protect engine performance and enjoy cleaner cabin air, while extending the life of the vehicle’s HVAC and intake systems.
