Our automotive air conditioning dust removal filter uses multi-layer composite filter materials, achieving a filtration efficiency of ≥95% for PM2.5, pollen, and dust particles, and ≥99% for PM10 particles. The product can be customized based on vehicle specifications provided by OEM clients, currently covering European, Japanese, American, Korean, and mainstream domestic vehicle models, compatible with over a thousand vehicle frame sizes. If there are special model requirements, our R&D team can complete sample development within 7-10 working days.

Yes, Cleantop officially obtained IATF16949 automotive industry quality management system certification in 2024, fully meeting the stringent requirements of automotive OEM/Tier1 supply chains. Additionally, the company holds ISO 9001, ISO 14001, and ISO 45001 certifications, and the products comply with European REACH, RoHS, and other environmental regulations. We can provide clients with complete compliance document packages, supporting exports to mainstream markets such as Europe, America, Japan, and South Korea.

We have over 20 years of experience in R&D and manufacturing of filtration products, supporting comprehensive OEM/ODM customization services, including: filter sizes and structures (square, round, custom shapes), filter material grades (standard dust removal type, PM2.5 high-efficiency type, activated carbon composite type, HEPA level), frame materials (paper frame, plastic frame, metal frame), customer logo printing, independent packaging, and color box design, etc. We have developed over 1,000 filtration solutions for global clients, with projects able to complete from design to mass production in as fast as 4-6 weeks.

Cleantop has a 50,000㎡ factory and six clean workshops covering 20,000㎡, and has built a nationally CNAS recognized testing center. Each batch of products undergoes complete process control from incoming material inspection (IQC), process inspection (IPQC), to finished product inspection (OQC). Critical tests include filtration efficiency, dust capacity, resistance, tensile strength, VOC release, and other indicators. The reports issued by the CNAS laboratory have mutual recognition validity worldwide and can be provided to clients with the shipment.

The MOQ for standard specification products is typically 1,000-2,000 pieces, while custom models generally start at 5,000 pieces depending on the mold opening. For ready stock products, we can provide free samples (shipping costs borne by the customer); custom samples will incur a nominal sample fee based on the complexity of development, which can be refunded in the first order after mass production. We encourage customers to validate samples first to ensure product performance fully meets requirements before bulk ordering.

Our standard product lead time is 15-25 days, while custom products are 30-45 days (including mold opening). Relying on a 50,000㎡ production base and multiple automated production lines, our monthly capacity can reach several million pieces, fully capable of supporting stable supply demands of large automotive brands and Tier1 suppliers. We have been continuously exporting to markets in Europe, America, Japan, and South Korea for over 20 years, possessing mature international logistics and supply chain management experience.

Under normal usage conditions, we recommend replacing our automotive air conditioning dust removal filter every 10,000-15,000 kilometers or every 6-12 months, depending on local air quality and usage environment. In areas with heavy dust or severe air pollution, it is advisable to shorten the replacement cycle. The product has undergone accelerated aging tests and dust capacity tests to ensure stable filtration performance and low wind resistance throughout its entire service life, without affecting the operational efficiency of the vehicle's air conditioning system.

The standard export packaging consists of: single piece PE bag + color box + outer carton, with the outer carton made of 5-layer reinforced corrugated cardboard to ensure no damage during long-distance transport. We fully support customer brand customized packaging, including color box design, logo printing, multilingual instructions, barcodes/QRCodes, anti-counterfeiting labels, etc., to meet brand retailers’ shelf display needs in a one-stop manner. After the design draft confirmation, packaging samples are usually completed within 3-5 working days.
