An air filter is not the same as an air conditioner filter. The function of the air filter is to filter the particulate impurities in the air, to ensure that a sufficient amount of clean air enters the cylinder, to prevent the dust suspended in the air from being sucked into the engine, and to accelerate the wear of the piston group and the cylinder. The air-conditioning filter is to filter the impurities, tiny particles, pollen, bacteria, industrial waste gas and dust contained in the air entering the interior of the car from the outside, so as to improve the cleanliness of the air and prevent such substances from entering the air-conditioning system and destroying the air-conditioning system.

Air conditioning filter and air filter maintenance method:
1. Air conditioning filter maintenance:
Check and replace the air conditioner filter according to the maintenance schedule. In dusty or heavy traffic areas, it may be necessary to replace it earlier, if airflow from the vent is significantly reduced, the filter may be clogged, check the filter. Replace if necessary. To prevent damage to the system, be sure to install a filter. Using the air conditioning system without a filter may damage the system. Do not clean the filter with water. When cleaning or replacing the air conditioner filter, the air conditioner system must be turned off first.

2. Air filter maintenance:
The dry habit air filter is composed of a dust cover, a deflector, a dust outlet, a vacuum cup, etc. When maintaining, you should pay attention to: Regularly check and clean the dust holes on the centrifugal dust cover, remove the dust adhering to the deflector, and pour out the dust in the dust cup. During installation, the sealing of the rubber gasket at the connection should be ensured, and there should be no air leakage, otherwise the air flow will be short-circuited, reducing the rotation speed of the air, and greatly reducing the dust removal effect.
