How to Maintain the Air Conditioning Filter?
3 Answers
The maintenance methods for the air conditioning filter are: clean the air conditioning filter promptly and replace it regularly. The filter is prone to accumulating dust, which can be removed by blowing compressed air or water gun to eliminate loose dust. If the filter is dirty, clean it by blowing compressed air from the opposite side, keeping a distance of 5cm from the filter and applying 500kPa pressure for about 2 minutes. Functions of the air conditioning filter: 1. Ensures the filter fits tightly against the housing to prevent unfiltered air from entering the cabin; 2. Separates solid impurities such as dust, pollen, and grinding particles from the air; 3. Adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air, with strong and lasting moisture absorption capability.
I've been driving for over a decade, and maintaining the cabin air filter is really super easy. I make it a habit to check it every six months or 10,000 kilometers. It's usually located under the glove box or below the windshield. Just open the cover, pull out the filter and inspect it – if it's full of dust and leaves, simply replace it with a new one. Compatible aftermarket filters are super cheap, saving you more than half compared to OEM parts. DIY is no hassle at all; just keep a screwdriver handy and you can swap it in under five minutes. Regular maintenance like this keeps the AC airflow strong and fresh, with no odd smells. Change it promptly during high pollen seasons in summer for better breathing comfort while driving. Developing this habit saves on repair costs – small spending prevents big problems, keeping your car clean and making driving much more enjoyable.
I've only been driving for a year and didn't know how to maintain the cabin air filter at first. A friend taught me to check the car manual to find its location—mine was in the glove compartment on the passenger side. After emptying the contents, removing the screws, and pulling off the cover, the filter was just a pleated paper sheet, completely black when I took it out. Following online videos, I bought a new filter and clumsily managed to fit it back in—my first attempt was a bit awkward but successful! Saved myself 40-50 bucks. Newbies, don’t stress—just prepare tools like small pliers for an easier job. Check the filter every 8,000 km or so. After doing it myself, I gained confidence to tackle other small projects. Developing a habit of checking is simple, safe, and practical.
