Breaking the airflow limits of traditional flat filters, specially designed for modern household/commercial and vehicle-mounted air purification devices. Utilizing a 360-degree surround air intake design, combined with high-efficiency PP/PET composite and PTFE nano materials, maximizing dust holding capacity and purification area. Effectively intercepting PM2.5, pollen, fine dust and other suspended particles, ensuring every breath is clean and safe.
Get Customized Specifications and QuotesAdopting a Cylindrical Structure Design significantly increases the effective filtration area of the filter. Compared to traditional flat filters, it can absorb polluted air from all directions, greatly enhancing the clean air delivery rate (CADR) of air purifiers and doubling the purification speed.
Precision folding technology allows for accommodating more efficient materials (PP/PET composite or PTFE) within a limited volume. Maximizing material utilization directly benefits the lifespan of the filter, lowering the user’s follow-up maintenance costs.
Supports customization of different levels of HEPA filter efficiency. Effectively intercepts PM2.5, pollen allergens, dust mite excreta, and other micron-sized or even nano-sized particles. Quality is strictly controlled based on the standards of the national CNAS testing center, meeting export standards for the U.S., Japan, and South Korea.

Cleantop has a 20,000㎡ cleanroom and 20 years of experience in the development and manufacturing of filtration products. We not only provide standardized high-efficiency dust collection filters, but we can also offer in-depth OEM/ODM structural customization and performance testing services for your new purification projects.
Consult the Engineering Team Now / Request Free SamplesOur standard cylindrical HEPA filters can cover levels from H11 to H14, with filtration efficiency for 0.3μm particles reaching over 99.995%. Specific parameters such as airflow, resistance, and dust holding capacity can be optimized based on your application scenario (household air purifiers, commercial fresh air systems, or industrial dust removal). All filters undergo performance testing at our national CNAS certified testing center before leaving the factory and complete test reports can be provided.
Fully supported. With over 20 years of R&D and manufacturing experience and over a thousand filtration solutions, we provide comprehensive customization services, including: filter dimensions (diameter, height), filtration levels (H11-H14), material selection (fiber glass, PP composite materials, etc.), end cap materials and structures (plastic, metal), sealing adhesive types, whether to incorporate activated carbon/formaldehyde removal layers, as well as packaging customization like color boxes, labels, and manuals. Our company has a professional R&D team that can reverse engineer based on your drawings or samples.
Cleantop has obtained ISO 9001, ISO 14001, ISO 45001 certifications, and our products have received multiple international certifications including European BSCI, U.S. EPA, NSF, and SOP. In 2024, we further obtained IATF16949 automotive industry certification and GMP certification for medical supplies. Our products have been exported in bulk to markets in Europe, the United States, Japan, and South Korea, fully meeting regulatory and access requirements in different regions.
Our main factory covers an area of 50,000㎡, of which 20,000㎡ is cleanroom (6 independent cleanrooms), ensuring HEPA filters are manufactured in a dust-free environment to avoid secondary contamination. Our quality control processes include: incoming quality control (IQC), in-process quality control (IPQC), finished product quality control (OQC), and performance verification at the CNAS laboratory (efficiency, resistance, dust holding capacity, PAO scanning leak detection, etc.). Each batch comes with a quality inspection report, ensuring product consistency and traceability.
We support sample supply for clients to conduct testing and market validation. Standard stock samples are usually shipped within 3-5 working days; customized samples generally take 7-15 working days to develop, depending on complexity. The cost of samples and shipping policies can be flexibly negotiated based on the intent to cooperate, and sample fees can usually be refunded after placing bulk orders.
The MOQ for standard cylindrical HEPA filters is typically 1000pcs, while for customized versions, the MOQ is subject to negotiation based on molding complexity. For sampling: existing specification samples can be sent out within 3-5 working days; customized molding samples generally take 15-25 working days to complete. Bulk order delivery periods are generally 25-35 days; we recommend that customers stock up in advance during peak periods. We have a mature supply chain and our own mold workshop, allowing flexible production scheduling according to customer order volumes to ensure timely delivery.
The lifespan of the filter depends on the air quality of the operating environment, runtime, and pre-filter configuration. In typical household or commercial environments, a replacement cycle of 6-12 months is recommended; in industrial high-load environments, replacements should be based on differential pressure monitoring. We can provide dust holding capacity test data and lifespan assessment recommendations based on actual application scenarios, helping end brands establish reasonable filter replacement prompt strategies.
Our cylindrical HEPA filters are widely used in household air purifiers, commercial fresh air systems, vehicle-mounted air purification devices, medical clean spaces, laboratory equipment, industrial dust removal, and semiconductor workshops, among various scenarios. Leveraging the technical accumulation of eight major product series, we can also combine HEPA with activated carbon, formaldehyde removal, ozone removal, and other functional layers to provide customers with integrated filtration solutions.
