🔧 CX-5 - Cabin Air Filter Replacement

Your CX-5’s cabin air filter cleans the air that comes through the HVAC (heat/AC) vents. Replacing it helps reduce dust/pollen and can improve airflow, especially if the fan feels weak or there’s a musty smell.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the cabin filter area

• Open the glove box fully.
• Use a flashlight to look behind the glove box for the cabin filter cover area.

Step 2: Release the glove box stops

• With both hands, gently push the glove box sides inward to clear the built-in “stops” (the little plastic blocks that prevent it from dropping).
• If a side trim edge is in your way, gently guide it using a plastic trim removal tool (specialty) (a plastic pry tool that helps prevent scratches).
• Let the glove box swing downward slowly.

Step 3: Remove the cabin filter cover

• Locate the rectangular filter access door behind the glove box.
• Use your fingers (or the plastic trim removal tool (specialty) if needed) to press the cover tabs and pull the cover off.

Step 4: Remove the old cabin filter

• Put on clean nitrile gloves and safety glasses.
• Slide the old filter straight out.
• Keep it level as you remove it so dust and leaves don’t dump into the blower case.
• Tip: A trash bag underneath helps catch debris.

Step 5: Install the new cabin filter

• Check the airflow arrow on the new cabin air filter.
• Install it in the same direction as the old one came out (airflow arrow must match the housing direction).
• Slide it in smoothly; don’t bend or crush the filter.

Step 6: Reinstall the cover and glove box

• Reinstall the filter cover and push until the tabs click into place.
• Lift the glove box back up and push the sides inward again so the stops pass into position.
• Close and open the glove box once to confirm it moves normally.

✅ After Repair

• Start your CX-5 and run the fan at medium speed for 30 seconds.
