There are two air filters in a 2022 Honda Civic: the engine air filter located in the engine bay and the cabin air filter hidden behind the glove box; both can be replaced by a DIYer in about 10–15 minutes each.
Overview: Two filters, two jobs
Why replace them
Replacing both filters helps maintain engine performance, fuel efficiency, and cabin air quality. A dirty engine filter can reduce power and increase fuel consumption, while a clogged cabin filter reduces airflow and can worsen interior odors.
Typical replacement intervals
Engine air filter: about every 30,000 miles under normal conditions (check owner’s manual for your exact interval). Cabin air filter: about every 15,000–20,000 miles, or annually, or sooner if you notice reduced airflow or odors. If you drive in dusty or urban environments, inspect earlier.
Tools and supplies
Before you begin, gather the tools and replacement filters you’ll need. Having a clean workspace and good lighting helps you complete the job quickly and safely.
- New engine air filter compatible with the 2022 Civic (OEM or equivalent, with proper size)
- New cabin air filter (often a 1-inch-thick, PM2.5-rated filter; confirm fitment)
- Screwdriver (Phillips) or flat-head as required by the air box fasteners
- Gloves and a flashlight
- Trash bag or dedicated container for old filters
- Optional: compressed air or a soft brush to clean the air box interior
Keeping the old filters for reference or disposal guidance is useful if your local recycling rules apply.
Replacing the engine air filter
Follow these steps to replace the engine air filter. Park on a flat surface, apply parking brake, and ensure the engine is cool before you start.
- Open the hood and locate the engine air filter housing, a rectangular black box connected to the intake hose near the front of the engine bay.
- Release the clips or screws securing the housing cover. If there is a screw, use a screwdriver; if clips, gently pry them with your fingers.
- Lift the housing cover and remove the old engine air filter. Take note of how the filter sits in the housing for proper orientation.
- Inspect the inside of the housing for debris and wipe it clean with a dry cloth if needed.
- Install the new engine air filter in the same orientation as the old one, ensuring the edges sit snugly in the housing and the airflow arrows point toward the engine.
- Reattach the housing cover and secure it with the clips or screws.
- Start the engine and idle for a minute to confirm there are no abnormal sounds and the intake is sealed. Close the hood when finished.
Regularly replacing the engine air filter helps preserve performance and reduces the risk of unmetered air entering the intake system.
Replacing the cabin air filter
Next, replace the cabin air filter, which sits behind the glove box. A clean cabin filter improves interior air quality and reduces odors.
- Open the glove box and remove its contents. In many Civics, you’ll need to press the sides of the glove box inward to release stoppers and let the box drop down.
- Rotate or remove the cabin filter cover; this is typically clipped or slid into place.
- Slide out the old cabin filter and inspect the filter housing for debris.
- Insert the new cabin filter with the airflow direction arrow pointing toward the rear of the vehicle (toward the blower).
- Reinstall the filter cover securely, then raise the glove box back into place and reattach any dampener arm or stoppers.
- Replace the contents of the glove box and close it fully. If you notice any reduced airflow after replacement, check the filter seating again.
Proper installation of the cabin filter ensures effective filtration of dust, pollen, and other particulates from the cabin.
Safety tips and disposal
Always dispose of old filters according to local regulations. Wear gloves to avoid skin contact with dust and allergens. If you’re unsure about fit or encounter damaging parts, consult a professional mechanic.
What to do after replacement
After replacement, keep a record of the date and mileage for future maintenance planning. If you drive in heavy dust or polluted areas, check the filters again sooner.
Summary
In a 2022 Honda Civic, you can replace both the engine air filter and the cabin air filter with basic tools in about 10–15 minutes per filter. The engine filter sits in the engine bay and is replaced by removing the housing cover and inserting a new filter with proper orientation. The cabin filter sits behind the glove box and is replaced by removing the glove box panel, swapping the old filter for a new one, and reassembling. Regular replacement maintains engine performance, fuel efficiency, and interior air quality.
