What is the function of a car air conditioning filter?

The function of a car air conditioning filter is to separate solid impurities such as dust, pollen, and grinding particles from the air, as well as to adsorb moisture, soot, ozone, odors, carbon oxides, SO2, CO2, and other substances in the air, providing strong and long-lasting adsorption. There are two types of air conditioning filters: one without activated carbon and another with activated carbon. The activated carbon air conditioning filter can absorb particulate matter, alleviate respiratory discomfort, reduce irritation for allergy sufferers, enhance driving comfort, and protect the air conditioning cooling system. Generally, the air conditioning filter should be replaced every 10,000 to 15,000 kilometers, but the actual usage conditions should be considered. If the filter appears excessively dirty, it should be replaced promptly.
Speaking of car cabin air filters, I have so much to say! This little thing may seem insignificant, but it's essentially the lungs of your car. During my daily commute through dusty construction sites, it blocks all the airborne particles for me - I even get fewer pollen allergies now. Last winter when the smog was terrible, the filter absorbed all those nasty smoke odors. The most noticeable improvement is that I don't sneeze anymore when using the AC. I usually replace it every six months - you can get decent ones online for about 20 yuan, and it only takes three minutes to DIY, way cheaper than dealerships. When overused, filters turn black and stiff, and if not replaced timely, they can actually breed bacteria. This is something everyone should really pay attention to.
