An air filter is a device that removes particulate impurities in the air. Mainly used in the fields of pneumatic machinery, internal combustion engine, etc.; the role is to provide clean air for these machinery and equipment, in case these machinery and equipment inhale air with impurity particles during work and increase the probability of abrasion and damage;

The air-conditioning filter filters the impurities, tiny particles, pollen, bacteria, industrial waste gas and dust contained in the air entering the cabin from the outside to improve the cleanliness of the air. To prevent such substances from entering the air conditioning system and destroying the air conditioning system, to provide a good air environment for the occupants in the car, and to prevent the glass from fogging.

The difference between air conditioning filter and air filter:
1. Different purification objects: The air filter element can filter the dust and particles in the air entering the engine. The air-conditioning filter element can filter the impurities contained in the air entering the cabin from the outside, small particles, pollen, bacteria, industrial exhaust gas and dust, etc., so as to improve the cleanliness of the air;
2. Different functions: The air filter element can make the engine inhale fresh and clean air well, so as to prevent sand and dust from entering the cylinder and abrading the cylinder, ensuring the normal operation of the engine. The air-conditioning filter element can improve the cleanliness of the air, prevent various impurities in the air from entering the air-conditioning system and destroy the air-conditioning system, and provide a good air environment for the passengers in the car;
3. The installation position is different: the air filter element is installed in the engine compartment. The air conditioner filter element is installed near the air inlet of the air conditioner, which is behind the blower.
