In complex urban roads and high-speed tunnels, exhaust fumes, pollen, and industrial dust can easily infiltrate the vehicle through the air conditioning system, posing a serious threat to the respiratory health of passengers. Cleantop relies on the IATF16949 automotive-grade manufacturing system, specially developing the High-Efficiency Composite Automotive Air Conditioning Filter for modern vehicles. The product ingeniously combines a high-precision HEPA filter layer with high-iodine value coconut shell activated carbon, effectively intercepting PM2.5 particles and deeply adsorbing harmful gases like ammonia and sulfides under extremely low air resistance conditions. This creates a medical-grade pure health cabin for you and your family.
Get Customized Solutions and Quotation for Automotive FiltersIn spring when pollen is rampant or during smoggy weather, external dust can easily enter the cabin through the air conditioning system. We have compounded high-precision HEPA filter materials that effectively intercept tiny PM2.5 particles, pollen, and bacteria carriers in the air. Ensuring exceptional clean air output rate (CADR), fully protecting mothers, infants, and sensitive individuals.
When driving in congested areas or long tunnels, external car exhaust and pungent odors can easily infiltrate the vehicle, causing dizziness. The filter layer selectively utilizes high-iodine value coconut shell activated carbon particles, targeting ammonia, sulfides, and various volatile harmful gases (VOCs) for deep targeted adsorption, keeping the air inside the car fresh and odor-free over the long term.
Inferior thick filters on the market often lead to sudden drops in air conditioning airflow, slow cooling/heating, and even cause blower noise. Cleantop adopts scientific precision folding technology and aerodynamic design optimization, achieving a perfect balance between high dust-holding capacity and ultra-low air resistance. While ensuring effective filtration, it maintains strong airflow and quiet operation of the air conditioning system.

Contact Our Engineering Team / Apply for Sample and Custom QuotationOur automotive air conditioning filters employ a multi-layer composite structure, integrating a HEPA high-efficiency filter layer, activated carbon adsorption layer, and antibacterial coating. The antibacterial layer can effectively inhibit the growth of common bacteria such as Escherichia coli and Staphylococcus aureus, achieving an antibacterial rate of over 99%. It also filters PM2.5, pollen, dust particles, and adsorbs odors and harmful gases (such as formaldehyde and benzene). Specific parameters can be customized according to customer requirements from OEMs or aftermarket, and we provide complete testing reports from our national CNAS laboratory.
Yes. Cleantop officially obtained the IATF 16949 automotive industry quality management system certification in 2024, fully meeting the procurement requirements of OEMs and Tier 1/Tier 2 suppliers. Additionally, we hold ISO 9001, ISO 14001, and ISO 45001 three-system certifications, ensuring comprehensive quality control from raw materials to finished products. Our products have stable supply to overseas markets in Europe, the United States, Japan, and South Korea.
Full support. Cleantop has over 20 years of experience in the research and manufacturing of filtration products, accumulating thousands of filtration solutions. We can provide comprehensive OEM/ODM customization based on customer specifications, dimension drawings, filtration efficiency requirements (such as PM2.5 and HEPA grades), antibacterial levels, and packaging design (logo, color boxes, manuals). From sample development to mass production, our R&D team can respond quickly within a short cycle, making products compatible with mainstream models such as BMW, Mercedes-Benz, Toyota, Honda, Volkswagen, and Tesla.
Cleantop's factory covers a total area of 50,000㎡, including 20,000㎡ of clean rooms, ensuring no secondary pollution in the filter production process. We have a nationally recognized CNAS testing center equipped with professional testing equipment for wind tunnel testing, particle counting, dust holding capacity, and antibacterial efficiency. Every batch of products undergoes strict incoming quality control (IQC), process inspection (IPQC), and finished product inspection (OQC) to ensure stable and consistent product quality.
Under normal usage conditions, we recommend replacing our automotive antibacterial filters after driving 15,000-20,000 kilometers or once a year; if the vehicle is used in heavily polluted or dusty areas, we recommend shortening the interval to 10,000 kilometers. The dust holding capacity and antibacterial effectiveness of the filter are rigorously verified in our CNAS laboratory, and detailed lifespan testing data reports can be provided to customers as procurement references.
The standard MOQ for regular models is usually 500-1,000 pieces; custom models are negotiated based on mold and material requirements (generally 2,000-5,000 pieces). The delivery time for regular products is 15-25 days, while the development cycle for custom products (including mold opening) is about 30-45 days, with a mass production delivery cycle of 25-35 days. We have a monthly production capacity of several million pieces, ensuring stable supply for large orders.
Yes. We welcome customers to request samples for testing to comprehensively evaluate product performance. Regular stock samples can be shipped within 3-5 working days; custom samples generally require 7-15 working days depending on complexity. Samples will be accompanied by testing reports from the CNAS laboratory, covering key indicators such as filtration efficiency, antibacterial rate, resistance, and dust holding capacity, facilitating verification in customer vehicles or real-world environments.
Our products have successfully been sold to markets in Europe, the United States, Japan, South Korea, and more. On a company level, we hold multiple international certifications such as BSC1 in Europe, EPA, NSF, SGS in the USA. For automotive air conditioning filters, we can provide the IATF 16949 system certificate, CNAS testing report, REACH, RoHS, antibacterial testing reports (such as ISO 22196/JIS Z 2801), and MSDS, assisting customers in smoothly clearing customs and meeting local regulatory requirements.
