If the air filter element is not replaced for a long time, it will be blocked and affect the intake of the engine, resulting in weak acceleration and increased fuel consumption. If the air conditioner filter element is not replaced for a long time, it will become clogged, which will affect the cooling and heating effect of the air conditioner. It is best to replace the filter element in one year, which is more beneficial to your health.

1. Air filter element: The air filter element can block out the dust and road dust entering the engine. These hard particles will cause internal wear of the engine, cause scratches on the cylinder surface, adsorb on the surface of closely matched parts, and cause surface wear of exposed and lubricated parts;
2. Air-conditioning filter element: The main component of the air-conditioning filter element is activated carbon, which is a highly effective adsorption material. As early as the "World War I", it was used in gas masks. Now activated carbon is widely used for air purification in cars or indoors;
3. Activated carbon is a kind of porous carbon-containing material. Its developed void structure makes it have a large surface area, so it is easy to fully contact with toxic and harmful gases in the air. The strong adsorption force field around the activated carbon pores will immediately suck toxic gas molecules into the pores, so activated carbon has a strong adsorption capacity.
