The main function of the filter element of automobile air conditioning is to filter the air in the car. But many people may not know where the air conditioner filter element is, or replace the high-priced filter element during 4S maintenance.

In the process of driving, the air inside and outside the car needs to be connected, and there are many kinds of pollutants such as dust, pollen, leaves, sand and gravel in the external air. The primary task of the air conditioner filter element is to filter these pollutants to ensure that the air entering the car is not polluted. Because once the pollutant enters the car, it will cause pollution when using the air conditioner, the cooling effect will be greatly reduced, and it will breed all kinds of bacteria and viruses in the air conditioning pipe. It poses a serious threat to human health. A good air-conditioning filter element not only hinders its own health, but also protects the steam-air conditioning system.

Now the filter element is also varied, except formaldehyde, filter PM2.5 and so on. In fact, it is the difference between with and without activated carbon, with activated carbon can remove odor. Those without activated carbon can filter some dust impurities in the air. Now there are still some with electrostatic adsorption, this effect will be better.

My car is a third-generation flying car that I bought in 14 years, and it has been 7 years this year. However, the number of runs is relatively small, and now it is only 95000 kilometers. In these years of use, in addition to routine maintenance, but also changed a lot of air-conditioning filter elements, including 9.9 free delivery, there are more than 100 imported green XX filter elements. In the car is the Boxin antibacterial air filter. This core is mainly antibacterial and filter PM2.5, the effect is quite good to use.

The air in spring is moist, everything is revived, and in the season of spring flowers, the air contains a lot of water and pollen. This time it uses KN multi-effect air conditioning filter element, with multi-layer filter, the filtering effect is very good, the filtering effect can be rated as mask-level protection, in addition to filtering pollen, but also can effectively filter PM2.5 dust. KN space by the front enhanced filter, in the air into the first time to isolate the dirt outside. After the pre-filtration, the activated carbon filter layer absorbs all kinds of harmful substances and PM2.5, and then sends the fresh air to the cab.

I am honored to participate in this trial experience of air conditioning grid and pass the examination. When I saw my name passed the examination, my heart was like a galloping horse and I was very excited. After the list was published, the editor was also very good, and without that long wait, he soon received the trial KN3007 air-conditioning box by express delivery. Get the first sense of the hand is to look forward to, forced to open the bag, the orange box reflects the eyes, as always the KN style. After packing, the air conditioner is wrapped in a plastic protective bag. Remove the plastic protective bag and expose the air. The first feeling is precision filtration. Under 120 times magnification, the fiber can be seen crisscross, ensuring the filtering effect while taking into account the performance.

Press the buckle on both sides, open the lid, and directly remove the original air conditioner filter element.

After changing the filter element of the air conditioner, I used it for a few days. Tell me about the effect of these days. First of all, the mildew smell disappeared as soon as the air conditioner was turned on, indicating that the filter element has played a very good deodorant effect. There is no special smell after the air conditioner has been on for a long time.
