Air-conditioning filter element is an indispensable part of car air-conditioning. Its function is to filter out the impurities in the air and make the air cleaner. The use of activated carbon air filter element has a stronger effect, and its adsorption capacity is stronger, which can adsorb harmful Gas, effectively filter PM2.5 in the air. However, there are advantages as well as some shortcomings. The air output is small and the manufacturing cost is high. Therefore, its price is more expensive than ordinary air-conditioning filters.

The air conditioner filter element is a component that needs to be replaced regularly. Once used for a long time, its performance will gradually weaken, such as the decline in adsorption capacity, etc., so it needs to be replaced regularly. Generally, it is best to change the seasons in autumn, winter, spring and summer. When the air conditioner is used, replace it. If it is not replaced for a long time, there may be a peculiar smell when the air conditioner is turned on, and bacteria may even breed, which will affect the health of the people in the car.
