Our rotary humidifier filter is made of high-quality spunlace non-woven fabric, characterized by its strong water absorption, high evaporation efficiency, antibacterial and anti-mold properties, and resistance to deformation. The filter's structure is designed in a rotary system that can rotate 360°, significantly improving the uniformity of humidification and mist output. The product is suitable for mainstream rotary evaporation-type (gasification) humidifiers, integrated air purification humidifiers, and commercial humidifying equipment. Specific parameters such as weight (gsm), water absorption rate, and evaporation efficiency can be customized according to customer model requirements, and Cleantop CNAS testing center can provide a complete third-party performance test report.

Fully supported. Cleantop has over 20 years of experience in the research and manufacturing of filtering products, providing a one-stop OEM/ODM service from material selection, structural design to finished product packaging. Customizable areas include filter dimensions (diameter, thickness, aperture), spunlace fabric weight and layers, frame color and material (ABS/PP, etc.), antibacterial treatment (silver ions, photocatalysts, etc.), logo printing, color boxes/blister/neutrals packaging, etc. Our company has a 50,000 m² factory and six clean workshops in Zhongshan, capable of matching the entire process from sampling to mass production.

Cleantop has passed ISO 9001, ISO 14001, and ISO 45001 system certifications, and has obtained international certifications such as Europe BSC1, US EPA, NSF, and SGS. In 2024, our company will further obtain IATF16949 and GMP certifications for medical supplies. For humidifier filter products that come into direct contact with water, we can customize compliant material solutions according to target markets (EU REACH, US FDA food contact-grade materials, Japan Food Sanitation Act, etc.), ensuring smooth entry into mainstream markets in Europe, the United States, Japan, South Korea, and more.

Cleantop has established a full-process quality control system from raw materials to finished products: 1) Incoming material inspection (IQC): raw spunlace fabric materials are tested for weight, water absorption rate, stretch strength batch by batch; 2) Process inspection (IPQC): 20,000 m² clean workshop production, key processes SPC process control; 3) Finished product inspection (OQC): sampling inspection of appearance, dimensions, structural strength according to AQL 2.5 standards; 4) CNAS nationally recognized testing center can issue authoritative test reports on evaporation performance, antibacterial rates, migration substances, etc. The implementation of the IATF16949 system further ensures product batch consistency.

Under normal household conditions (8 hours of usage per day, using purified or softened water), the recommended replacement cycle for the standard spunlace fabric humidifier filter is 3-6 months; if using the high-end antibacterial enhanced version, it can extend to 6-12 months. We can provide various functional upgrade solutions, including silver ion antibacterial, nano photocatalyst, dechlorination, and scale removal coatings, with antibacterial rates reaching over 99% (tested according to JIS Z 2801 or ISO 22196 standards). Specific lifespan data can be simulated and verified in our CNAS laboratory based on customer water quality and operating conditions.

The standard MOQ is typically 1000 PCS, while the customized MOQ depends on the mold and material situation and is generally above 3000 PCS. Sample policies: existing specification samples can be provided for free (freight collect); customized samples will incur a sampling fee, which can be refunded after bulk ordering. Delivery timelines: the stock period for regular inventory items is 7-15 days, while OEM custom orders take about 25-35 days, and mold projects are calculated separately for the mold cycle. Our 50,000 m² self-owned factory and mature supply chain can ensure delivery capabilities during peak seasons.

Cleantop was established in 2002, focusing on the research and manufacturing of air and water filtering products for over 20 years, accumulating over 1000 filtering solution cases, covering 8 major product lines including HEPA filters, activated carbon filters, humidifier filters, coffee machine water purifiers, and medical high-efficiency filters. Our company has long served overseas brands in Europe, the United States, Japan, South Korea, and OEM factories and trading partners, with specific client lists available for further discussion after signing NDAs, and customers are also welcome to visit our headquarters in Zhongshan for on-site inspections.
