Follow these steps carefully
Open the passenger-side glove box and take everything out. You need a clear swing path — the whole box has to drop down out of your way.
Press the left and right walls of the glove box inward until the two side tabs clear their slots, then let the box swing down toward the floor — it hangs on its lower hinges.
Look into the opening where the glove box sat. You'll see a black plastic cover with a raised hexagonal texture — the cabin filter door. Pinch its retaining tabs and pull it straight toward you. It lifts off with no screws on the tenth-generation Civic.
Grip the old filter's edge and slide it out. Before tossing it, look at the airflow arrows on its frame — on the Civic they point DOWN toward the floor, because the blower sits below the filter. Note which way they face.
From my bay, Arrows down on the Civic — the blower sits below the filter. Every car is different, so always match the old filter's arrows, never your memory.
Slide the new filter in with its airflow arrows pointing down, exactly matching the old one. Push it all the way in until the frame sits flush with the housing opening — a half-seated filter lets dusty air bypass around it.
Press the hexagonal cover back over the housing until its tabs click. Tug lightly to confirm it's seated. A loose cover rattles over bumps and can whistle when the fan runs at high speed.
Raise the glove box, press both sides inward so the tabs catch their slots, then close it. Start the car and run the fan through a few speeds with the A/C on.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
