Our cylindrical water spray humidifier filter uses high-quality water-absorbing fiber material and a honeycomb structure design, providing a large unfolded area and strong water absorption, with a humidification efficiency of over 85%. Under standard conditions, the lifespan is 6-12 months (depending on water quality and usage frequency). The product is widely applicable for household humidifiers, commercial central air conditioning, industrial humidification systems, humidity control in data centers, dust-free workshops, and places like museums and archives that require constant humidity environments.

We support comprehensive OEM/ODM services. Relying on a 50,000㎡ factory and over 20 years of research and manufacturing experience, we can customize the filter's diameter, height, thickness, honeycomb pore size, water absorption material (fiber paper/PP/aluminum-based, etc.), central support structure, and antibacterial coating according to customer needs. Custom services like logo printing, color box design, and neutral packaging are also provided to help brand owners quickly create differentiated products.

Cleantop has passed ISO 9001, ISO 14001, and ISO 45001 certifications and obtained various international certifications such as European BSC1, US EPA, NSF, and SOP. In 2024, we added IATF16949 (automotive industry) and GMP certification for medical products. Products are bulk exported to markets in Europe, the United States, Japan, Korea, etc., fully meeting compliance requirements for each target market, and we can assist in obtaining relevant certifications for customer requirements.

We have established a complete quality control system from raw material arrival to finished product shipment: ① we have 20,000㎡ clean workshops (6 total) to ensure the production environment is pollution-free; ② a national-level recognized CNAS testing center can conduct all tests for water absorption rate, permeability, antibacterial properties, structural strength, etc.; ③ we implement three levels of inspection: IQC, IPQC, OQC, with samples retained from each batch for reference. Batch stability is guaranteed by an SPC statistical process control system, keeping the defect rate at an industry-leading level.

Yes, our water spray humidifier filter can optionally come with silver ion (Ag+) antibacterial treatment or nano photocatalyst coatings, achieving over 99% antibacterial rate, effectively inhibiting the growth of common bacteria such as E. coli and Staphylococcus aureus, and significantly reducing secondary contamination and odor generation. The antibacterial performance is verified by the CNAS laboratory and test reports conforming to NSF or EU standards can be provided upon customer request.

The standard MOQ is usually over 3000 pieces, specific according to specifications; the MOQ for custom products typically starts from 5000 pieces. The lead time for standard products is 7-15 days, for custom products the sample cycle is 7-10 days, and mass production lead time is 30-45 days. For large orders and long-term cooperating customers, we can provide VMI stocking plans and priority production services to ensure supply chain stability.

We welcome sample testing. Standard specification samples can offer 1-3 free samples, with customers only needing to bear the international express freight. Custom specification samples require a sampling fee (which can be refunded after bulk production). Our CNAS testing center can provide a complete performance testing report along with samples, including key indicators like water absorption rate, humidification efficiency, material safety, etc., to help customers quickly complete product verification.
