In recent years, the rapid development of auto industry, stimulating the demand for auto parts market, provide a broad market space for China's automotive filters.

So air filter manufacturer has a explosive growth. there are more than 1000 automotive filters factories in China but many are family workshop style.
The good and the bad are intermingled can not make sure auto filters quality, so the phenomenon of do shoddy work and use inferior material is very common. Many customer have the experience of being cheated .
So before buy the auto filters customer need to do a comprehensive inspection on the manufacturers, well from which aspects to inspect the air filter manufacturer?

Like jieyu filter’s product approved by European and American market, is the air filter supplier for Top 500 enterprise so customer so consumers more assured of their filters.

4. Manufacturer's testing equipment.
Filter media is the main raw material of automotive filters but many small manufacturers do not have filter media test equipment, they always used the inferior quality filter media to reduce the cost, done a shoddy job with substandard material.
