How to Replace the CRV Air Conditioning Filter?
4 Answers
Here are the steps to replace the CRV air conditioning filter: 1. Carefully open the outer shell of the car's air conditioning system from the passenger side. 2. Reattach the outer shell of the car's air conditioning system, then turn on the air conditioning to test if it functions properly. 3. Functions of the air conditioning filter: (1) Ensures the filter fits tightly against the shell, preventing unfiltered air from entering the cabin. (2) Separates solid impurities such as dust, pollen, and abrasive particles from the air. (3) Adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air, with strong and long-lasting moisture adsorption capabilities.
Last year, I changed the CRV's cabin air filter myself and realized how simple it was. First, empty the glove compartment on the passenger side, then press both sides inward to remove the compartment. Next, pull off the black cover behind it. When removing the old filter, remember the arrow direction—on my 2019 model, the arrow points downward. The new activated carbon filter I bought was only 30 yuan. Just slide it in until it clicks into place, then reinstall the glove compartment. The whole process takes 20 minutes without any tools, saving over 100 yuan in labor costs compared to a dealership. Now, I replace it every six months, always before turning on the heater in winter, which is especially helpful for people with sinusitis. Before starting, it's best to check the vehicle manual to confirm the arrow direction—some older models have it pointing upward.
My decade of experience running an auto repair shop has taught me that the glove box damper rod tends to break when removing the CRV's cabin air filter. Here's a trick—support the bottom of the box with both hands, lift it up 15 degrees, then pull outward. This way, the three clips release easily. The filter slot cover has a small protrusion that needs to be pinched. When pulling out the old filter, be careful not to shake dust into the air ducts. For filter selection, I recommend composite materials with PM2.5 filtration—especially useful during pollen season. Northern car owners should ideally replace it twice in spring, as sandstorms can easily clog the filter. During reinstallation, you'll hear a click when it's properly seated. If the AC airflow noticeably increases, you've succeeded.
Last month, I just replaced the cabin air filter for my new CR-V. The key is to buy the correct model—providing the last seven digits of the VIN to the seller ensures the most accurate match. When removing the glove box, use your knee to support the bottom while releasing the clips on both sides; even a woman can do it single-handedly. If the old filter is blackened, it's time for a replacement—remember to wear a mask when shaking off the dust to avoid coughing. Before inserting the new filter, wiping the inner walls of the air duct with a damp cloth works wonders. After installation, run the AC at maximum speed for five minutes, and the musty smell in the car will be gone. Now, I change it every 8,000 kilometers, and the DIY cost is less than 50 yuan.
