How to Replace the Car Air Conditioning Filter?
5 Answers
Here are the steps to replace the air conditioning filter: 1. Open the glove compartment and pull down the small hook on the right side. 2. Squeeze both sides of the glove compartment inward to remove it. 3. Release the clips on both sides and pull out the air conditioning filter housing. 4. Remove the old filter, install the new one, and reassemble the glove compartment to complete the process. There are generally two types of air conditioning filters: 1. Standard air conditioning filter: Made from a specific eco-friendly filtration material that undergoes processing and folding, typically appearing as a single white layer. This basic filter primarily prevents dust and particles from entering. 2. Activated carbon air conditioning filter: Constructed with non-woven fabric on both sides sandwiching fine activated carbon particles, forming an activated carbon filter cloth, which is then processed into an air conditioning filter. It utilizes the physical properties of activated carbon to adsorb tiny particles and more harmful substances from the air in a short period as air passes through, offering significantly better filtration than standard filters.
I often change my car's cabin air filter myself, and I find it quite simple. The first step is to locate the filter, which is usually behind the glove compartment on the passenger side. Open the glove box, and there might be a small cover or screws securing it. I use a small screwdriver to remove the screws and take off the cover. At this point, you can see the old filter. After removing it, check how dirty it is—no wonder there's sometimes a bad smell or poor cooling in the car. You can buy a new filter online or at a supermarket for just a few dozen yuan. Make sure to choose the model that matches your car. When installing, pay close attention to the small arrow on the filter—it should point downward or inward. Installing it the wrong way reduces filtration efficiency. After replacing it, close the cover properly and test the airflow by turning on the AC. The air will immediately feel much fresher. I also recommend changing it every 10,000 kilometers or every six months, especially for people with allergies, as it helps reduce pollen and dust entering the cabin. Doing it yourself saves money and gives peace of mind. Don’t overlook this small maintenance task—it keeps your driving experience healthy. Like me, I keep a few spare filters on hand and change them during smoggy days—it really lifts my mood.
Having driven for over 10 years and changed air conditioning filters hundreds of times, I've summarized some insights. The filter is usually located behind the glove box - after opening it, you'll need to remove the cover screws, but don't use excessive force to avoid damaging plastic parts. When you pull out the old filter, check how black it is - that's your reminder to replace it. Choose a new filter that matches your vehicle model, preferably the activated carbon type which is better at odor removal. During installation, remember the arrow should point toward the vehicle interior or downward - this is where beginners often make mistakes by installing it backward. Common issues include mismatched filters causing airflow obstruction, which leads to increased AC noise. DIY replacement costs less than 50 yuan, saving you over 100 compared to repair shops. I recommend car owners replace it annually or every 12,000 kilometers to maintain optimal AC system efficiency. Don't underestimate this small task - it saves money in the long run and prevents bacterial growth. Make it a habit to check during regular maintenance - the whole process takes about 10 minutes without needing special tools.
As a health-conscious mom, regularly changing the car's cabin air filter is essential. It's located behind the glove box on the passenger side - just open the cover to access it. The old filter is usually clogged with dust, making cleaning difficult. Replacing it is simple: purchase a compatible filter online, align it properly in the slot (pay attention to the arrow direction), and it'll work fine. This ensures cleaner air inside the car, especially reducing allergy symptoms during pollen season. I recommend checking it quarterly - these affordable filters cost only 20-30 yuan, and replacement takes just half an hour. Prioritize health by preventing dirt buildup; you'll enjoy smoother breathing and more comfortable driving.
I change the air conditioning filter myself to save money. The filter only costs 30 to 50 yuan online, compared to the minimum 100+ yuan labor fee at a 4S shop, which is too expensive. The location is behind the glove box—just remove the cover panel. Take out the old filter to check how dirty it is, then insert the new one, making sure the airflow arrow direction is correct to avoid reducing efficiency. Always match the car model to avoid wasting money on the wrong part. The whole process takes less than ten minutes and requires no tools. The money saved can be used for gas or other purchases. I replace it every 15,000 kilometers or once a year to maintain high AC efficiency and avoid repair costs. It’s a small investment with big returns—make it a habit.
