Addressing the issues of outdoor smog invasion and the difficulty of removing indoor formaldehyde and odors, Cleantop has specially designed a new generation Fresh Air / Fresh Air Conditioning Composite Filter for you. The product deeply integrates high-efficiency composite PP (Polypropylene) filtering material with high iodine value activated carbon, which not only accurately intercepts PM2.5, pollen, and fine dust but also effectively adsorbs indoor TVOCs and harmful gases. It provides a powerful stream of clean and fresh air for central fresh air systems and fresh air conditioning, creating a truly high-quality healthy living environment.
Get Customized Fresh Air Filter Solutions and QuotesThe core of the fresh air system lies in bringing clean outdoor air indoors. Our filter uses high-precision composite PP (Polypropylene) filtering material, offering a broad efficiency range from F7 to H13. It effectively intercepts smog, pollen, dust, and various harmful particles from entering indoor spaces, thoroughly eliminating the pain point of “unfresh fresh air.”
A single dust filter cannot resolve gaseous pollutants. We creatively integrated a modified activated carbon filter module, possessing strong microporous adsorption capability. It can keenly capture and decompose formaldehyde, TVOCs, and other volatile organic compounds released from renovations, as well as odors from outdoor vehicle emissions, keeping indoor spaces fresh for a long time.
Fresh air machines and fresh air conditioning units from different brands have varying dimensions. Leveraging Cleantop's 20,000㎡ clean workshop's strong production capacity and testing capabilities, we offer fully flexible OEM/ODM filter customization services. Regardless of dimensions, frame, or filter material combinations, we can deliver precisely based on customer specifications.

Our R&D team can provide exclusive designs based on your fresh air machine model or air conditioning structure.
Our factory covers an area of 50,000㎡, including 6 clean workshops totaling 20,000㎡, ensuring that HEPA filters are produced in a dust-free environment to avoid contamination. In terms of quality control, we have a CNAS national-level accredited testing center, and we possess complete testing capabilities including scanning leak detection, efficiency testing, resistance testing, and dust capacity testing. Each batch of products carries out triple quality control processes of incoming IQC, process IPQC, and outgoing OQC, ensuring batch consistency and product reliability.
Under standard fresh air system usage conditions, the typical lifespan of our HEPA filters is 6-12 months, with specific lifespan depending on the air quality of the usage environment, operational duration, and pre-filter configuration. We recommend pairing G4 pre-filters with F7/F8 medium efficiency filters in areas with high PM2.5 levels to extend HEPA primary filter lifespan. We can provide different dust capacity specifications based on your target market.
The MOQ for standard products is usually 500-1000 pieces. For customized products, the MOQ varies based on specification complexity, and we also provide flexible small batch trial order support for new customers.
