How to identify the quality of car air filter?

The quality of the air filter mainly depends on the following three aspects:
(1) Waterproof performance of air filter: There is a lot of moisture in the air, especially in rainy days, the water content in the air will be higher. Once the waterproof performance of the air filter is not good, the air filter will be easily damp. Once the air filter is damp It will affect the smooth suction of the air machine, or even block it.

(2) Filtration accuracy of air filter: If the filtration accuracy is not high, a small amount of dust and impurities will be sucked into the air compressor in large quantities, thus affecting the service life of oil, oil, oil filter, bearings, etc.

(3) Air filter air permeability: If the air filter air permeability is not good, it will also affect the smooth suction of the air compressor, which is easy to block and consumes a lot.
