We are a manufacturer of automotive filters, and every product we produce undergoes quality testing.

As an automotive filter manufacturer, we place a high emphasis on product quality. Therefore, every product we produce undergoes rigorous quality testing to ensure that our customers receive high-quality filter products.

Our quality testing process includes the following steps:

Firstly, we test the raw materials to ensure that they meet our quality requirements. We use certified materials that undergo inspection and testing before use.

Next, we use these raw materials to manufacture filter products while monitoring and testing the manufacturing process strictly. These tests include dimension, density, filtration efficiency, pressure drop, and other aspects.

After production, we conduct comprehensive testing and inspections on each filter product to ensure that they meet our quality standards. These tests include pressure testing, leak testing, dust holding capacity testing, and other aspects.
