Ordinary air purifier filters can only intercept dust and easily become breeding grounds for bacteria and viruses in humid environments, producing sour odors and secondary pollution. Cleantop has specially developed the Flat HEPA+ Antibacterial Composite Filter. This combines high-precision physical interception with long-lasting medical-grade antibacterial and antiviral coatings. It not only efficiently filters out pollen, pet dander, and cigarette particles in the air but also actively inactivates Influenza A virus, Escherichia coli, and Staphylococcus aureus. Certified by authoritative agencies with a dust mite removal rate as high as 82.4%, it builds a truly sterile and healthy living environment for you and your family.
Get Custom Antibacterial Filter Solutions and QuotesHigh-tech antibacterial and antiviral agents are firmly attached to the HEPA filter fiber. It actively attacks not just physically intercepting airborne microbial aerosols but also effectively destroying bacterial cell walls, inhibiting and inactivating Influenza A virus, E. coli, and Staphylococcus aureus, completely preventing the filter from becoming sour or smelly after prolonged use.
Spring pollen and seasonal dust mites are common pathogens that trigger allergic rhinitis and asthma. This composite filter not only has a high physical interception rate for pollen and pet dander but also passed the authoritative testing according to FZ/T01100-2008 standard, achieving a professional mite removal rate of 82.4%, allowing mothers and infants, as well as sensitive individuals to breathe freely at home.
Using a high-density folding flat structure design, it maximizes the use of the limited airflow space inside the purifier. Without increasing the thickness of the device, it achieves the dual effect of “HEPA high precision particle interception + medical-grade antibacterial and antiviral properties,” significantly simplifying the structural design challenges for terminal OEM manufacturers and enhancing commercial value.

Contact Engineering Team / Apply for Custom Solutions and Sample TestingOur flat antibacterial HEPA filter can provide filter efficiencies ranging from H11 to H14 according to customer requirements, with a maximum filtration efficiency of up to 99.995% for 0.3μm particles. The antibacterial layer is treated with certified antibacterial agents, achieving inhibition rates of over 99% for common strains such as E. coli and Staphylococcus aureus. All performance data is tested by our national-level CNAS accredited testing center based on standards such as EN 1822 and GB/T 13554, and a complete testing report can be provided with the shipment.
Yes, as a manufacturer with over 20 years of experience in the air filtration industry, we offer complete customization services for global brand owners and OEM customers, including: filter size and thickness, filtration grades (H11-H14), frame materials (paper frame, plastic frame, metal frame), filter material combinations (HEPA + activated carbon + integrated antibacterial layer), folding count and sealing strip processes, as well as packaging customization such as color boxes, labels, and manuals. Our mature ODM development team can quickly sample according to customer’s purifier model.
Cleantop has passed ISO 9001, ISO 14001, and ISO 45001 management system certifications. Our products and factory have received multiple international certifications including European BSC1, US EPA, NSF, and SOP. In 2024, we will also add IATF 16949 (automotive quality management) and medical supplies GMP certifications, fully meeting the compliance requirements for mainstream markets such as Europe, the US, Japan, and South Korea. We can also assist customers in applying for additional certifications required for target markets such as CARB, REACH, and RoHS.
Our factory is located in Zhongshan, Guangdong, covering an area of 50,000㎡, including 6 clean workshops with a total area of 20,000㎡ specifically for the production of HEPA and medical-grade high-efficiency filters, preventing contamination of filter materials during manufacturing. Each batch of products undergoes scanning leak detection (PAO/DOP testing), efficiency testing, resistance testing, antibacterial performance sampling, combustion grade testing, and other comprehensive QC processes in the CNAS laboratory to ensure high consistency in performance between batches, with defect rates strictly controlled at an industry-leading level.
Standard specification samples can be provided within 3-5 working days, while custom specification samples usually require 7-15 working days, depending on structure complexity and mold conditions. The costs for regular samples can be refunded in subsequent bulk orders. We encourage customers to conduct adequate sample testing and installation verification before placing orders, and our technical team will fully cooperate with customers to complete adaptation and optimization.
The usual MOQ for standard specification products is 500-1000 pieces, while the MOQ for customized specifications depends on materials and structure, generally ranging from 2000-3000 pieces. The regular order delivery period is 25-35 days after placing the order; for large quantities or long-term cooperative customers, we can arrange VMI stock plans to shorten delivery times. With a capacity of 50,000㎡ and automated production lines, we have the ability to meet large-scale order deliveries consistently.
Each batch of HEPA filters must undergo the following tests before shipment: appearance and dimension inspection, initial resistance testing, filtration efficiency testing (0.3μm DOP/PAO), scanning leak detection testing, random sampling for antibacterial performance, and combustion grade testing. The reports issued by our CNAS testing center are internationally recognized and can be coordinated with third-party inspection and testing agencies like SGS, Intertek, and TÜV to ensure delivery quality is traceable and verifiable.
Our flat antibacterial HEPA filter is widely used in household and commercial air purifiers, fresh air systems, car air purifiers, terminal filters for air conditioning, medical air purification devices, and small clean equipment. With its antibacterial layer design, it is especially suitable for homes, mother-and-baby, medical, and office environments with high requirements for microbial control. We can provide the optimal filter material formulation and structural方案 according to specific working conditions such as airflow, resistance, and installation size.
