3 Answers
The method to replace the Civic's cabin air filter is as follows: 1. Open the glove box, press both sides of the glove box inward to remove it; 2. The cabin air filter is located behind the glove box, then press the clips on both sides of the filter cover outward to pull it out; 3. Install the new cabin air filter by following the original steps in reverse. Taking the 2021 Civic as an example, it is a compact car with body dimensions of: length 4517mm, width 1799mm, height 1434mm, and a wheelbase of 2700mm. The 2021 Civic is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 117PS, maximum torque of 220Nm, maximum power of 130kW, and is paired with a CVT continuously variable transmission.
Replacing the Civic's cabin air filter is actually quite simple, and I do it myself regularly. First, let's talk about the location—the filter is usually behind the glove box. The first step is to open the glove box, then you'll notice clips on both sides. Gently press or pull them outward to remove the glove box, but don't use too much force to avoid damage. Next, locate the filter slot, typically covered by a plastic lid. Lift the lid to reveal the old filter, carefully pull it out, and pay attention to the arrow direction on the filter (facing downward), which indicates the airflow direction—never install it backward. Before inserting the new filter, double-check that the model matches the Civic to avoid size mismatches. I usually buy OEM or certified brands for reliable quality. During installation, push the new filter back into place with the arrow facing downward, close the lid, and reattach the glove box. The whole process takes just a few minutes—saving money and hassle—and immediately improves cabin air quality, which is great for health. Regular replacement also extends the AC system's lifespan.
As a car enthusiast who loves tinkering, I've changed quite a few Civic cabin air filters. The key is removing the glove box—open it, locate the clips, press and release them to remove the box and expose the filter compartment. Don’t toss the old filter right away; checking how dirty it is helps gauge usage frequency. The standard replacement interval is typically every 10,000 km or six months. Pay attention to the new filter’s orientation—the arrow pointing downward indicates airflow direction. Installing it backward can reduce efficiency or even cause blockages. Be careful not to damage the glove box or wiring during the process; I prefer wearing gloves to minimize scratches. After replacement, start the car and test the AC airflow—no strange noises means success. This job doesn’t require a dealership visit, saving hundreds in labor costs. The filter itself costs just a few dozen bucks, and with plenty of online tutorials available, it’s easy to pick up—even beginners can learn it. Regular maintenance keeps your car running smoother.
