The Zanxis cylindrical humidifier filter (water spray type) is a pleated, honeycomb-structured water filter for cold-evaporation, wick-based humidifiers. It draws water by strong capillary action and releases moisture as air passes through, while intercepting calcium and magnesium ions in the water to help limit white dust. It is built for owners of home humidifiers, high-end air purifiers with humidification, and industrial constant-temperature/humidity equipment who need a replaceable, specification-controlled filter. Zanxis manufactures it in Zhongshan, Guangdong, China, with full OEM customisation of dimensions and structure.
| Item | Detail |
|---|---|
| Product name | Cylindrical humidifier filter / air purifier humidification core |
| Core humidification material | High-absorption humidifier paper / polymer humidifier fiber |
| Core performance | Strong capillary water absorption and water-molecule evaporation; intercepts calcium and magnesium ions in water (helps block white powder); long-acting antibacterial and anti-mold; removes water-tank odours |
| Physical structure advantage | Dense pleated honeycomb process gives a very large evaporation area and very high wet stiffness; it does not collapse or fall apart during long soaking in the water tank |
| Main application endpoints | Household cold-evaporation, no-mist humidifiers; high-end air purifiers with humidification; industrial constant-temperature and constant-humidity equipment |
| Specification and size customisation | 100% OEM flexible custom manufacturing. Outer diameter, inner diameter, height, pleat count of the cylinder, and whether an anti-mold/antibacterial composite coating is needed can all be precisely manufactured to drawing requirements |
| Quality certification system | Manufactured in the company's 50,000 m² modern clean plant; the company holds ISO 9001, ISO 14001 and IATF 16949 international quality management system certifications and controls quality with a national-level CNAS testing laboratory |
Before a design is frozen, confirm the values that govern fit and humidification behaviour. For a cylindrical filter, the outer diameter, inner diameter and height determine whether it seats correctly in the water tank and around any centre support; the pleat count and honeycomb geometry affect evaporation area and airflow resistance. Confirm the expected water quality, because hardness and mineral content influence how quickly calcium and magnesium deposits accumulate on the media. Confirm the required antibacterial/anti-mold option and whether the filter must carry a composite coating. Confirm the operating water temperature and the typical continuous soaking period. Finally, confirm the target service interval and the humidifier's airflow, so the selected media grade and pleat density match the duty. Zanxis reviews these values against the drawing before quoting.
The filter is built around high-absorption humidifier paper or polymer humidifier fiber, folded into a dense pleated honeycomb that presents a large evaporation surface in a compact cylinder. The pleated structure gives the media very high wet stiffness, so it holds its shape during long soaking in the water tank instead of softening, collapsing or shedding material. The capillary effect pulls water upward through the media quickly, and the moisture is released as air moves through the pleats. The media is designed to intercept calcium and magnesium ions, which helps reduce the white powder associated with hard water, and the optional antibacterial and anti-mold treatment supports long-term freshness by limiting odour and microbial growth in the water tank.
Typical installations are household cold-evaporation, no-mist humidifiers, high-end air purifiers with a humidification function, and industrial constant-temperature/constant-humidity equipment. Because every humidifier tank and air path differs, Zanxis manufactures to drawing: outer diameter, inner diameter, height, pleat count and the choice of antibacterial coating are all customer-defined. This makes the filter suitable both for replacement programmes and for new appliance platforms where a standard cylinder does not fit. During use, keep the tank clean and follow the humidifier maker's water recommendations. When evaporation output drops or deposits become visible, replace the filter; in standard conditions the service life is 6–12 months, depending on water quality and usage frequency.
Zanxis supports filter verification with its own laboratory, which is accredited by CNAS (China National Accreditation Service for Conformity Assessment) and can issue test reports covering filtration efficiency, dust holding capacity and resistance. For humidifier filters, the relevant checks centre on water absorption, wet structural integrity, media consistency and the optional antibacterial treatment. Quality control runs through IQC, IPQC and OQC, so incoming media, in-process pleating and finished cylinders are each inspected against the approved specification.
The company holds ISO 9001, ISO 14001 and ISO 45001 system certifications and added IATF 16949 automotive quality management system certification in 2024. Production takes place in a 50,000 m² plant in Zhongshan, Guangdong, China, which includes 6 clean workshops totalling 20,000 m². Products comply with REACH and RoHS environmental requirements, and compliance documents can be supplied. With more than 20 years of filtration research and manufacturing experience and more than 20 years of continuous export to Europe, the United States, Japan and South Korea, Zanxis has developed over 1,000 filtration solutions and runs multiple automated production lines with monthly capacity reaching several million pieces. OEM/ODM support covers dimensions, structure, filter media grade, frame material, logo and packaging.
To receive samples and the matching test reports, send the following to our team: your device or vehicle model, the required size or drawing, the airflow or water flow, the operating conditions (water quality, temperature, target service life), and the estimated quantity. We will confirm the media and structure, quote the sample and production order, and issue the CNAS-accredited laboratory report for the agreed specification. Start your request through the contact page.
Yes. Zanxis can issue test reports from its own CNAS-accredited laboratory covering efficiency, dust holding and resistance, and for this product the relevant checks include water absorption and wet structural integrity. The report is tied to the agreed specification and sample. Share your drawing and operating conditions so the correct test scope is confirmed.
Sample validation follows the drawing review and pre-production sample stage; timing depends on the specification and the tests required. Zanxis confirms the schedule with the quotation, after receiving your device model, size or drawing, airflow or water flow and operating conditions. The approved sample is then locked as the production reference.
Confirm the outer diameter, inner diameter, height and pleat count, plus the antibacterial/anti-mold option and expected water quality. Also confirm the operating water temperature, continuous soaking period and target service life. These values determine fit in the tank and the humidification behaviour, so they are reviewed against the drawing before quoting.
Yes. Zanxis supports 100% OEM flexible custom manufacturing: cylinder outer diameter, inner diameter, height, pleat count and the choice of anti-mold/antibacterial composite coating can be made to drawing. Logo and packaging customisation are also available. Send the device model and drawing to start the review.
The MOQ for this product is set per specification and is confirmed in the quotation, together with lead time and sample policy. Because dimensions and media are customisable, the quantity depends on the agreed drawing and production run. Provide your estimated annual or per-order quantity for a precise answer.
Lead time is confirmed with the quotation and depends on the specification, quantity and test requirements. Zanxis runs multiple automated production lines with monthly capacity reaching several million pieces, which supports volume orders. The schedule is fixed after sample sign-off.
In standard conditions the service life of this cylindrical humidifier filter is 6–12 months, depending on water quality and usage frequency. Replace it when evaporation output drops or mineral deposits become visible. Keeping the water tank clean and following the humidifier maker's water recommendations helps maintain performance.
Send your device or vehicle model, size or drawing, airflow or water flow, operating conditions and quantity through the contact page. Zanxis will confirm the media and structure, quote the sample and production order, and issue the CNAS-accredited laboratory report for the agreed specification.
