In response to the modern design trend of air purifiers and fresh air devices, which constantly pursues “light, thin, and small,” traditional bulky filters have become a bottleneck in product iteration. Cleantop's newly launched Flat Panel HEPA Filter (MAX Series) features a unique ultra-flat design that maximizes the filter area within a minimal thickness. Not only does it efficiently intercept fine particles, but it also maintains extremely low air resistance, providing air purifier manufacturers with a high CADR consumable solution that combines a minimalist appearance with outstanding purification performance.
Get Custom Purification Filter SolutionsThe design of air purifiers increasingly pursues lightweight and thin profiles. We use high-density hot-melt folding technology to tightly compress high-efficiency filter media into a MAX flat panel filter. The extremely thin design significantly saves air duct space inside the air purifier, enhancing the aesthetic appeal and commercial competitiveness of the end product.
Thickness is reduced without compromise on purification performance. The product relies on a dual mechanism of deep physical interception and electrostatic adsorption to precisely target PM2.5, pollen, pet dander, and suspended fine dust as small as 0.3μm in the air. This ensures every breath of air released from the purifier meets exceptionally high cleanliness standards.
The core filter materials provide a variety of choices including PP (Polypropylene Meltblown), PP+PET Composite Materials, and High-end PTFE Membranes. HEPA filtration levels can be flexibly customized according to the power of the customer's fan and target CADR (Clean Air Delivery Rate) to meet diverse scenario needs.

Whether you are looking for a standardized filter manufacturer that offers high cost-performance or seeking a customized ultra-thin and high-performance HEPA filter for your latest smart appliances, Cleantop, with over 20 years of experience and thousands of filtering solutions, will be your most reliable supply chain partner.
Contact Engineering Team / Apply for Custom Solutions and SamplesOur flat panel HEPA filters can provide efficiency levels from H11 to H14, with a filtration efficiency of up to 99.995% for 0.3μm particles (according to EN 1822 standards). The products are widely used in household and commercial air purifiers, fresh air systems, vehicle purifiers, medical equipment, and industrial clean environments. Each batch of products undergoes scanning leak testing and efficiency testing in our nationally recognized CNAS laboratory to ensure stable and reliable performance.
We fully support OEM/ODM customization services. We can customize filter dimensions, thickness, folding number, frame material (paper frame/plastic frame/aluminum frame/galvanized frame), sealing glue type, filtration grade (H11-H14), and packaging schemes (customer logo, color box, manual, etc.) per customer requirements. Leveraging over 20 years of R&D experience and a library of over a thousand filtering solutions, our engineering team can complete the scheme design and sample-making within 7 working days.
Cleantop has obtained ISO 9001, ISO 14001, and ISO 45001 management system certifications, and multiple international certifications including European BSC1, US EPA, NSF, and SOP. In 2024, we added IATF16949 (automotive industry) and medical product GMP certifications. Our products have been exported in bulk to Europe, the USA, Japan, and South Korea, fully complying with target market regulations and access requirements, with complete certification documents and testing report support for customer customs clearance and brand endorsement.
We have a 50,000㎡ factory, of which 20,000㎡ is composed of 6 clean workshops (with a highest level of ISO Class 7). We have set up 12 QC inspection processes from raw material entry, cutting, folding, frame sealing to finished product shipment. Each roll of HEPA filter media undergoes efficiency, resistance, and dust holding capacity testing in the CNAS laboratory, and finished products undergo 100% scanning leak testing (PAO/DOP testing). Combined with IATF16949's PPAP and SPC process control, we ensure batch-to-batch performance consistency CPK≥1.33.
The MOQ for standard products is usually 500-1000 pieces, and the MOQ for customized products depends on the size and structural complexity, generally between 1000-3000 pieces. The lead time for standard products is 15-20 days, while customized products take 25-35 days after sample confirmation. The sample-making cycle typically takes 5-10 working days, and we can provide free samples (freight collect) to facilitate performance evaluation and model compatibility testing for customers.
Our CNAS nationally recognized testing center is equipped with professional equipment such as laser particle counters, aerosol scanning leak testing platforms, dust holding capacity testing platforms, and TSI 3160, capable of providing full testing including filtration efficiency (EN1822/ASHRAE/GB), resistance curves, dust holding life, PAO/DOP leak testing, formaldehyde/TVOC removal rates, ozone removal rates, etc. Customers can obtain legally binding third-party reports or schedule on-site verification tests (FAT), and the process is open and transparent.
In a typical household environment (average annual PM2.5 35μg/m³, running 8 hours daily), the suggested lifespan of the flat panel HEPA filter is 6-12 months; for commercial and industrial environments, it is suggested to be 3-6 months. We can provide dust holding capacity testing data and lifespan curves based on customer application conditions to assist customers in setting reasonable pressure differential alarm thresholds or filter replacement indication algorithms, improving the end-user experience.
As a professional manufacturer with over 20 years of industry experience, Cleantop can provide partners with: (1) One-stop filtering solutions (with a library of over a thousand mature solutions); (2) Complete certification and compliance document support (EPA/NSF/CE/GMP, etc.); (3) Dedicated product manager liaison with English/Japanese technical support; (4) Exclusive regional agent policies; (5) Exhibition and marketing material support (product images, testing videos, white papers).
