Learn how to pick the right cabin air filter for your Honda Civic or Acura Integra and install it yourself in minutes with our step-by-step guide.

Quick Answer

For a 2016-2021 Honda Civic or 2017-2021 Civic Type R, choose a genuine Honda cabin air filter (part numbers 80291-T5R-A01 and others) and replace it every 15,000 miles or once a year. The install takes about 10 minutes with no tools.

Why a Genuine Honda Filter Matters

Genuine Honda cabin air filters are engineered to match the exact dimensions and airflow requirements of your vehicle. Aftermarket filters may fit loosely, allowing unfiltered air to bypass the media and reducing filtration efficiency.

Using a genuine filter also helps maintain consistent HVAC performance, which is especially important if you drive in dusty or polluted conditions.

Signs You Need a Replacement

Common indicators include reduced airflow from the vents, musty odors when the AC or heat is on, and increased dust on interior surfaces. If you notice any of these, check the filter first—it's the easiest and cheapest fix.

If you frequently drive in heavy traffic or areas with poor air quality, consider replacing the filter more often than the standard interval.

Step-by-Step Installation Guide

Locate the cabin air filter housing: In most Honda Civics and Acura Integras, the filter is behind the glove box. Open the glove box and squeeze the sides to release the stops, then let it hang down to access the filter cover. If the glove box doesn't drop, check for a damper cord that needs to be unclipped first.
Remove the old filter: Press the tabs on the filter cover and pull it out. Slide the old filter straight out, noting the airflow arrow direction (usually pointing toward the rear or the cabin). Take a photo of the old filter's orientation before removal—this is a common mistake that leads to installing the new filter backwards.
Install the new filter: Insert the new genuine Honda cabin air filter with the airflow arrow pointing in the same direction as the old one. Slide it in until it sits flush, then snap the cover back on. Make sure the filter is not folded or crumpled at the edges; it should fit snugly without forcing.
Reattach the glove box and test: Lift the glove box back into place and reattach any damper cord. Turn on the HVAC fan to confirm airflow is strong and even through all vents. If airflow is weak, double-check that the filter is installed with the correct orientation and that the cover is fully sealed.
