Our cylindrical humidifier filter is made from high-quality spunlace non-woven fabric as the core filtration material. The spunlace fabric features evenly distributed fibers, strong water absorption, excellent moisture retention, and high evaporation efficiency. Compared to traditional non-woven fabrics, its humidification efficiency can be improved by over 20%, and it is less prone to lint generation, ensuring the cleanliness of the air expelled from the humidifier. The filter structure adopts a cylindrical three-dimensional design, effectively increasing the contact area with the air, resulting in more efficient natural evaporation humidification.

Under normal home use conditions (8 hours of use per day), the recommended replacement cycle for this spunlace humidifier filter is 3-6 months, with the specific lifespan depending on local water hardness and usage frequency. The filter supports rinsing with clean water to remove surface mineral deposits, but using chemical cleaners is not recommended. We can provide upgraded versions with added antibacterial and descaling treatments based on the water quality situation in the customer's target market to extend the product life.

We fully support OEM/ODM customization, which is one of our core advantages. Based on over 20 years of experience in the development of filtration products and thousands of accumulated solutions, we can customize the diameter, height, center hole diameter, layers, weight of spunlace fabric (usually 50-120gsm), colors, and end cap materials (PP/ABS/EVA, etc.) based on the customer's humidifier model. We also support customized color boxes, labels, instruction manuals, and other packaging solutions to help customers quickly create their own brand products.

Cleantop has obtained ISO 9001, ISO 14001, ISO 45001 management system certifications and holds international certifications such as EPA, NSF, and European BSC1. In 2024, we also achieved IATF16949 automotive industry certification and GMP certification for medical supplies. Our humidifier filter products comply with environmental regulations such as EU REACH and RoHS, allowing them to smoothly enter major markets including Europe, the USA, Japan, and Korea, helping customers avoid compliance risks.

We have a 50,000㎡ factory that includes six clean workshops totaling 20,000㎡, ensuring the humidifier filters are produced in low-dust environments to avoid secondary contamination. The company has a nationally recognized CNAS testing center, and each batch of raw materials and finished products must undergo various tests including weight, water absorption rate, evaporation amount, microorganisms, and water resistance. From raw material entry, cutting, forming, assembly to packaging and shipping, we implement a comprehensive SOP operation to ensure consistent product performance and stable quality for each batch.

We provide free standard samples for B2B customers (freight collect). Custom samples are generally completed within 7-10 business days after finalizing the drawings and specifications. With 20 years of mold development experience and a mature supply chain, we can quickly respond to customers' customization needs, providing professional structural optimization suggestions in the sample stage to shorten the customer's product development cycle.

The MOQ for standard cylindrical humidifier filters is usually 1,000 PCS, while custom models are negotiated based on mold and material conditions. The lead time for mass production is generally 25-35 days after receiving the deposit; peak season or large orders can be planned in advance. Our production capacity is sufficient to support an annual shipment of over one million units, meeting the long-term procurement needs of brand owners and large traders.

First, professional accumulation: Cleantop has focused on air and water filtration for over 20 years since 2002, accumulating thousands of filtration solutions; second, R&D strength: having a CNAS nationally recognized laboratory, we have independent R&D and performance validation capabilities; third, manufacturing assurance: 50,000㎡ factory + 20,000㎡ clean workshop, equipped with IATF16949 and GMP-grade quality control standards; fourth, global vision: our products have been exported to many countries in Europe, the USA, and Japan, deeply understanding the standards and customer needs of each market, making us a strategic supplier worth long-term cooperation.
