How often does the filter element of the car air conditioner change? What brand has good quality?

About the air conditioning filter, let's talk about its function first. We know that car air conditioners, like household air conditioners, will produce impurities, dust and bacteria after a period of use. If these impurities and dust are blown directly into the car, the air environment inside the car will become worse, affecting the health of drivers and passengers. Air-conditioning filter element is used to filter the impurities in the air blown into the car from the air conditioner and optimize the air quality inside the car.

After absorbing impurities and dust for a period of time, the air conditioning filter element itself will be polluted, and it will not play a role in purification and filtration. If you continue to use it, it will have the opposite effect of aggravating pollution, and the air conditioner will have insufficient refrigeration, insufficient wind at the outlet, odor and so on.

Some car owners will say, as long as you take out the filter element, blow it with an air gun and blow off the dust, you can continue to use it? Theoretically, if the air-conditioning filter element is not used for a long time, it will be better to blow it temporarily. However, the air-conditioning filter element does not only filter dust, but a better filter element can filter bacteria and pollen, and even the PM2.5 air gun can only blow off the dust on the surface. Pollen, bacteria or PM2.5 can never be blown off. Only by replacing the air conditioning filter element can it be completely solved.

So how often should the air conditioner filter be changed? Under normal circumstances, it is generally recommended to replace 654.38+100000 kilometers or once a year. If your vehicle often travels in areas with serious air pollution, or you pay more attention to the hygiene of air conditioning and your own health, it is best to shorten the replacement time.

There are many kinds of air-conditioning filter elements, the filter paper type is the simplest and most common, and there is another filter element with activated carbon, which has the function of moisture-proof and odor absorption. The latest one should be HEPA air-conditioning filter element, which has a good effect of filtering particulate matter and can filter PM2.5 The functions of these three air-conditioning filter elements are different, so the owner can choose according to his own needs and economic factors when replacing them.
