Addressing the issues of outdoor smog invasion and the difficulty of removing formaldehyde and odors indoors, Cleantop has developed a new generation of Composite Filter for Fresh Air / Fresh Air HVAC especially for you. The product deeply integrates efficient composite PP (Polypropylene) filter material with high iodine value activated carbon, effectively intercepting PM2.5, pollen, and fine dust, while also strongly adsorbing indoor TVOC and harmful gases. It provides clean and fresh air for central fresh air systems and fresh air HVAC, creating a truly high-quality healthy living environment.
Get Customized Fresh Air Filter Solutions and QuotationsThe core of the fresh air system lies in introducing clean outdoor air indoors. Our filter uses high-precision composite PP (Polypropylene) filter material, offering a broad efficiency range from F7 to H13. It effectively intercepts smog, pollen, dust, and various harmful microparticle pollutants from entering indoors, completely resolving the issue of “the fresh air not being fresh.”
A single dust removal filter cannot resolve gaseous pollution. We creatively integrated a modified activated carbon filter module, which has strong microporous adsorption capability. It can sensitively capture and decompose formaldehyde, TVOC, and other volatile organic compounds released during decoration, as well as odors from outdoor vehicle exhaust, keeping the indoor environment fresh for a long time.
Different brands of fresh air machines and fresh air HVAC come in various sizes. Leveraging Cleantop's powerful production capacity and testing capabilities in a 20,000㎡ clean workshop, we offer fully flexible OEM/ODM filter customization services. Regardless of size, frame material (paper frame, aluminum frame, plastic frame), filter material grade (H11/H12/H13), folding number and height, or the addition of activated carbon/antibacterial/formaldehyde removal composite layers, product labels, and packaging design, we can accurately deliver according to customer specifications.

Contact Engineering Team / Apply for Custom Solutions and Sample ProductionOur Fresh Air HVAC HEPA filters can provide products ranging from H11 to H13 according to customer needs, achieving a filtration efficiency of 95% to 99.97% for 0.3μm particles. They are compatible with mainstream brands of fresh air HVACs, wall-mounted air conditioners, floor-standing units, and central air conditioners. We have a database of over a thousand filtering solutions that can quickly match or develop corresponding specifications based on your specified model.
In a standard home environment, we recommend a usage period of 6-12 months for our HEPA filters, with the specific lifespan depending on the air quality and usage time in the environment. The company has a nationally recognized CNAS testing center that can conduct comprehensive testing on key parameters such as dust holding capacity, resistance, and filtration efficiency according to EN 1822, GB/T 6165 standards, and provide authoritative testing reports to customers, with data that is credible and traceable.
We fully support OEM/ODM customization services, which is also one of our core advantages. We can customize filter sizes, frame materials (paper frame, aluminum frame, plastic frame), filter material grades (H11/H12/H13), folding numbers and heights, and whether to add activated carbon/antibacterial/formaldehyde removal composite layers, product labels, color box and packaging design, etc. With over 20 years of R&D experience and a 20,000㎡ clean workshop, we can complete sample prototypes within 2-4 weeks.
The company has passed ISO 9001, ISO 14001, and ISO 45001 system certifications, as well as several international certifications such as BSC1 from Europe, EPA from the USA, NSF, and SGS. In 2024, we added IATF 16949 automotive industry system certification and GMP certification for medical supplies. Our products are steadily exported to markets in Europe, the USA, Japan, Korea, etc., fully complying with the access standards for mainstream markets in Europe and America, and can provide corresponding certification documents to support customs clearance and sales for customers.
Cleantop's factory covers an area of 50,000㎡, including 6 clean workshops totaling 20,000㎡. HEPA filters are produced in a class 1000/100,000 clean environment to avoid secondary pollution. The quality control process spans four key stages: incoming material inspection (IQC), production process inspection (IPQC), complete product inspection (FQC), and outgoing quality control (OQC). Each batch passes filtration efficiency and resistance testing by a CNAS laboratory to ensure batch consistency and zero-defect delivery.
The standard product MOQ is usually 500-1000 pieces; the MOQ for customized products is determined through negotiation based on specific specifications and packaging requirements, generally ranging from 1000-3000 pieces. The delivery time for standard products is 15-25 days, while customized products (including mold opening) take 30-45 days. The company has the capability for large-scale mass production, ensuring stable and rapid delivery for large orders, and can flexibly adjust production capacity during peak seasons to prioritize key customers.
We welcome customers to request samples for testing and evaluation. Existing standard specification samples can be provided for free, with the customer bearing the international express delivery costs; for customized specification samples, a certain fee will be charged based on the complexity of development, which can be refunded after a bulk order is placed. We have a professional R&D team that can assist customers throughout the entire process from sample evaluation to mass production.
