Our automotive air conditioning filters use a multi-layer composite filter material structure combined with an activated carbon adsorption layer, achieving a filtering efficiency of over 95% for PM2.5 particles, while effectively adsorbing harmful gases and VOCs such as formaldehyde and benzene series, as well as eliminating odors. The product is compatible with mainstream vehicle models worldwide, including European, Japanese, American, and domestic brands. Customers can provide vehicle information or sample dimensions for accurate matching and mold customization.

Under standard conditions, we recommend a replacement cycle of 6-12 months or after driving 15,000-20,000 kilometers for our automotive air conditioning filter (odor removal), depending on local air quality and usage environment. In areas with heavy smog or dust, we recommend shortening the replacement cycle to ensure filtration effectiveness. We can adjust the filter material weight and activated carbon content according to customer market demands to extend the actual service life of the product.
