In response to the challenges of outdoor haze intrusion and the difficulty in eliminating indoor formaldehyde and odors, Cleantop has specially created a new generation of Fresh Air / Fresh Air Conditioning Composite Filter for you. The product deeply integrates high-efficiency composite PP (Polypropylene) filter material with high iodine value activated carbon, effectively capturing PM2.5, pollen, and tiny dust particles while strongly adsorbing indoor TVOC and harmful gases. It provides a steady stream of clean, fresh air for central fresh air systems and fresh air conditioning, building a truly high-quality, healthy living environment.
Get Fresh Air Filter Customization Plans and QuotesThe core of the fresh air system lies in introducing clean outdoor air indoors. Our filters use high-precision composite PP (Polypropylene) filter material, providing a wide efficiency selection from F7 to H13. They effectively intercept smog, pollen, dust, and various harmful particles from entering indoors, completely eliminating the problem of “fresh air not being fresh.”
A single dust filter cannot solve gaseous pollution. We have innovatively integrated a modified activated carbon filter module with strong microporous adsorption capability. It can sensitively capture and decompose formaldehyde, TVOC, and other volatile organic compounds released from renovations, as well as the odor of outdoor vehicle exhaust, keeping the indoors fresh for a long time.
Different brands of fresh air machines and fresh air conditioners come in various sizes. Leveraging Cleantop’s strong production capacity and testing strength with a 20,000㎡ clean workshop, we offer fully flexible OEM/ODM filter customization services. Regardless of size, frame, or filter material combination, we can accurately deliver according to customer drawings.

Contact the Engineering Team / Apply for Custom Plans and SamplesOur fresh air / fresh air conditioning odor removal filters adopt HEPA high-efficiency filtration layers and high-quality activated carbon composite structures, with particulate filtration efficiency reaching H11-H13 levels (≥ 95%-99.95% for 0.3μm particles), while also exhibiting excellent adsorption capability for TVOC, formaldehyde, ammonia, hydrogen sulfide, and other odor gases. The product is widely applicable to household fresh air systems, fresh air conditioners, central air conditioning return segments, commercial purification devices, etc. All performance parameters have been verified by our national CNAS testing center, ensuring data authenticity and reliability.
Under normal usage conditions (with an annual average PM2.5 concentration of around 35μg/m³, running 8-12 hours daily), the suggested replacement cycle is 6-12 months. The specific lifespan depends on local air quality, usage frequency, and pollutant concentration. We can provide customized dust holding capacity and activated carbon iodine value plans based on the environmental data of the customer's area, optimizing filter lifespan and cost-effectiveness.
Cleantop has passed ISO 9001, ISO 14001, and ISO 45001 system certifications and holds product certifications from Europe BSC1, the US EPA, NSF, and SOP. In 2024, we also obtained IATF16949 automotive industry quality certification and GMP certification for medical products. Our products have been successfully exported to markets in Europe, the US, Japan, South Korea, and more, fully compliant with the regulations and customer access standards of the target markets, helping customers quickly pass downstream brand audits.
We support comprehensive OEM/ODM customization services. Specific aspects include: ① Size and shape (square, round, folding, roller, etc.); ② Filtration grades (G4 to H14); ③ Types and loading of activated carbon (coconut shell carbon, coal-based carbon, modified carbon, honeycomb carbon, etc.); ④ Frame materials (aluminum frame, galvanized frame, paper frame, plastic frame); ⑤ Packaging customization including brand labels, color boxes, instruction manuals, barcodes, etc. With over 20 years of industry experience and more than 1000 filtration solutions available, we can quickly respond to customer personalized needs.
Cleantop has a factory covering 50,000㎡, with 20,000㎡ allocated to 6 independent clean workshops, ensuring no secondary pollution in HEPA filter production. We have established a comprehensive quality control system from incoming material inspection (IQC), process inspection (IPQC) to outgoing product inspection (OQC). The nationally recognized CNAS testing center can conduct full-scale testing for PM filtration efficiency, resistance, dust holding capacity, gas adsorption rate, formaldehyde CADR, and all shipped products come with a testing report, ensuring performance stability and consistency between batches.
The standard product MOQ is usually 500-1000 pieces, depending on product specifications; the MOQ for customized products is generally 1000-2000 pieces. We can flexibly accept sample orders. Regarding delivery periods: conventional stock products are shipped within 7-10 days; the first order of customized orders takes about 25-35 days (including mold/sample creation), while repeat orders take 15-25 days. We have sufficient production capacity reserves and can arrange VMI stocking plans for long-term cooperative customers.
We welcome customers to request samples for real testing and evaluation. Regular specification samples can be provided free of charge, and the customer only needs to bear international shipping costs. Sample fees for custom specifications will be charged based on the complexity of mold making, but can be refunded upon bulk ordering. We can also provide third-party testing reports issued by the CNAS laboratory, assisting customers in completing technical reviews and project approvals.
The activated carbon used in our products is made from food-grade/environmentally friendly materials, passing RoHS and REACH hazardous substances tests, free from heavy metals, formaldehyde, and other VOC release sources. For high-end application scenarios such as medical, maternal and child, and automotive, we can also provide low-release, low-dust activated carbon solutions that meet GMP standards and IATF16949 automotive requirements, along with full safety validation conducted by the CNAS laboratory to ensure product quality and safety at the end-user level.
