This Zanxis cylindrical humidifier filter is a self-priming evaporative wick made from spunlace non-woven fabric, designed to draw water upward and release moisture into the air stream of cold-evaporation humidifiers and humidifying air purifiers. It intercepts calcium and magnesium ions from tap water to help prevent white dust, and its antimicrobial treatment resists mould and odour. It is intended for appliance OEMs and brand owners who need a custom-sized, verifiable wick for household or commercial humidification systems.

Before a sample is built, the specification values that most affect humidifier performance should be agreed in writing. For the wick itself, confirm the outer diameter, inner diameter and height of the cylinder, the pleat count, and the spunlace fabric grade. These dimensions determine both the fit in the water tray and the evaporation area available at your airflow. Confirm the water-contact requirement: whether the standard antimicrobial and anti-mould treatment is sufficient, or whether an additional antimicrobial coating is needed for your target market's water hardness.
Confirm the operating conditions the filter will see: continuous immersion depth, water quality (hardness and mineral content), airflow through the element, and the expected replacement interval in your appliance. These values let Zanxis match the fabric grade and pleat geometry to the duty. Also confirm packaging, logo and any compliance documentation required for the destination market. Because the product is fully customised, agreeing these values at the quotation stage avoids rework at sample approval.
Zanxis builds humidifier filter samples against confirmed drawings and verifies them before mass production. The workflow is:
This sequence gives a documented record from drawing to approval, so the delivered filters match what was validated.
The filter is a pleated cylinder made from spunlace non-woven fabric. Spunlace fabric has an even fibre distribution, strong water absorption and good water retention, which supports rapid wicking and evaporation. The dense pleating increases the surface area in contact with the air, so a compact cylinder can deliver a large evaporation area. The fabric is treated with an antimicrobial and anti-mould process to resist the sour odour that can develop in humidifier wicks. Its wet strength keeps the pleats upright during long immersion, so the element does not soften or break apart in the water tray.
Typical installations are household cold-evaporation wick humidifiers, premium air purifiers with a humidification function, and commercial or industrial constant-humidity equipment. The filter is self-priming: it draws water up through the fabric by capillary action, and the airflow across the pleats carries the moisture away. Because the element intercepts calcium and magnesium ions, it helps limit white dust on furniture and surfaces. The filter can be rinsed in clean water to remove surface mineral deposits; chemical cleaners are not recommended. In normal household use, a replacement interval of 3 to 6 months is typical, depending on local water hardness and daily running hours.
Zanxis supplies this filter as an OEM/ODM component. Cylinder dimensions, pleat count, fabric grade and optional coatings are made to the customer's drawing, and packaging, logo and documentation can be customised. With more than 20 years of filtration development and over 1,000 filtration solutions, the company can support the specification of a wick that matches a given humidifier platform.
Zanxis operates a self-built laboratory accredited by CNAS (China National Accreditation Service for Conformity Assessment), which can issue test reports covering filtration efficiency, dust holding capacity and resistance. For humidifier filters, this laboratory supports the verification of absorption, evaporation and resistance values on samples and production batches. Quality control runs through IQC, IPQC and OQC: incoming materials are checked, in-process parameters are monitored, and outgoing filters are inspected before shipment.
The company holds ISO 9001, ISO 14001 and ISO 45001 system certifications, and obtained IATF 16949 automotive quality management certification in 2024. Products comply with REACH and RoHS environmental regulations, and compliance documents can be provided. Manufacturing takes place in a 50,000 m² plant, which includes six clean workshops totalling 20,000 m², supporting low-dust production of humidifier wicks. Zanxis has more than 20 years of filtration product development and manufacturing experience and has exported to Europe, the United States, Japan and South Korea for over 20 years. The address is Zhongshan, Guangdong, China.
To receive a quotation, a sample and the relevant test report, please send the following details: your humidifier or appliance model and the installation space; the required size or a drawing (outer diameter, inner diameter, height, pleat count); the airflow through the filter and the water flow or immersion conditions; the water hardness and operating environment; and the estimated order quantity. Zanxis will review the values, confirm the fabric grade and configuration, and provide a sample plan with test documentation. Contact us through /en/contact to start the verification process.
Zanxis can issue test reports from its CNAS-accredited laboratory covering absorption, evaporation and resistance values for the sample and production batches. Filtration efficiency and dust holding reports are also available where relevant. Reports are tied to the agreed specification, so the values you see correspond to the sample you approve.
After the drawing and specification are confirmed, sample fabrication typically takes 7 to 10 working days, followed by laboratory verification and fit checks. The total time depends on the complexity of the dimensions and any optional antimicrobial coating. The sample and its test report are then sent for your sign-off before production.
Confirm the outer diameter, inner diameter, height and pleat count against the water tray and airflow path of your appliance, or supply the appliance drawing. Zanxis reviews these values and proposes the fabric grade and pleat configuration. A sample is then built to those dimensions for a physical fit check.
The MOQ for standard cylindrical humidifier filters is typically 1,000 pieces; customised sizes are quoted separately depending on tooling and material requirements. MOQ is confirmed with the quotation after the specification is agreed. Larger volumes can be scheduled with the same production and inspection flow.
Mass production lead time is generally 25 to 35 days after deposit receipt, depending on order quantity and scheduling. The plant has multiple automated lines with monthly capacity in the millions of pieces. Firm dates are given in the quotation so you can plan launches and replenishment.
In normal household use, a replacement interval of 3 to 6 months is typical, depending on local water hardness and daily running hours. The filter can be rinsed in clean water to remove surface mineral deposits, but chemical cleaners are not recommended. For harder water, an antimicrobial-coated version can be specified to extend service life.
Yes. Zanxis supports OEM/ODM customisation of the cylinder's outer diameter, inner diameter, height and pleat count, as well as the spunlace fabric grade and optional antimicrobial coating. Logo, packaging and documentation can also be customised. Custom work is produced to your drawing and verified by sample before mass production.
