The Jyntrel cylindrical humidifier filter is a self-priming wick element made from spunlace non-woven fabric, built to draw water upward by capillary action and release it into the airstream as moisture. It filters the water film carried on its pleated surface, intercepting calcium and magnesium ions that would otherwise leave white dust downstream, and it is intended for humidifier and air-purifier makers who need a stable, replaceable wick in evaporative, fan-driven air paths. Jyntrel supplies it as an OEM component, sized to the device drawing rather than to a fixed catalogue list.
In a cold-evaporation humidifier the filter sits between two media at once: a standing water bath at the base and a moving air stream drawn through the cylinder wall. The fabric must wick moisture against gravity along its full height while air passes through the pleated wall at the velocity set by the fan. The two demands pull in opposite directions — a denser, more absorbent web holds water well but adds resistance, while an open web passes air freely but dries unevenly. Spunlace construction balances this because the fibre web is bonded by hydroentanglement, giving a uniform pore structure along the whole cylinder rather than a dense skin on one face.
The pleated pack raises the wetted surface area exposed to the air path, so evaporation happens across a wider face at the same duct velocity. Because the wall is a cylinder, air enters from all sides, which suits axial and mixed-flow fan layouts where the intake surrounds the element. Relative humidity, inlet temperature and fan speed all shift the evaporation rate; the fabric is selected to stay wetted across that range rather than to a single test point.
Water uptake depends on capillary action in the fibre network. A high capillary effect means water climbs quickly from the trough and the wetted face is replenished as fast as the air stream removes moisture, which is what self-priming operation requires. The spunlace web is produced with a high wet strength, so the cylinder keeps its shape during long immersion and does not soften, sag or delaminate in the sump.
Water hardness is the second variable. The media is built to retain calcium and magnesium ions within the wetted structure, limiting the mineral load carried into the air as white dust. A special anti-mould and antibacterial treatment is applied to resist souring and odour development in the tank, a common complaint where a wick stays damp between cycles. These three behaviours — fast wicking, wet strength and mineral retention — define how the element performs inside a running device.
The cylinder is fully customisable for OEM programmes. Outer diameter, inner diameter, height and pleat count can all be set to your assembly drawing, and an antibacterial coating can be added where the target market calls for it. Selection starts from four inputs:
| Item | Detail |
|---|---|
| Product name | Cylindrical humidifier filter / air purifier humidifying core |
| Core filter material | High-absorption humidifying paper / humidifying polymer fibre / spunlace non-woven fabric |
| Core performance | Strong water absorption and fast evaporation; retains calcium and magnesium ions to limit white dust; long-acting antibacterial and anti-mould action; reduces tank odour |
| Physical structure | Dense pleating for a large evaporation area; high wet stiffness; resists collapse and separation during prolonged immersion in the water trough |
| Main end applications | Household cold-evaporation (no-mist) humidifiers, air purifiers with humidifying function, commercial and industrial humidity-control equipment |
| Size and customisation | OEM customisation supported: outer diameter, inner diameter, height, pleat count and optional antibacterial coating made to your device drawing |
| Quality system | Produced in the company's 50,000 m² plant; ISO 9001, ISO 14001 and IATF 16949 certified; CNAS-accredited testing laboratory |
The element is used in household cold-evaporation humidifiers that produce no visible mist, in air purifiers that combine filtration with humidification, and in commercial and industrial humidity-control equipment where a wetted cylinder sits in a ducted or cabinet air path. In each case the duty is the same: bring water to the air surface steadily and keep minerals out of the discharge.
Jyntrel has more than 20 years of filter development and manufacturing experience and has exported to Europe, the United States, Japan and South Korea for over 20 years, which gives buyers a stable supply base for repeat programmes. Multiple automated production lines support output in the millions of pieces per month. Production runs in a 50,000 m² plant that includes six clean workshops totalling 20,000 m². Quality is controlled through IQC, IPQC and OQC stages, and the in-house laboratory holds CNAS accreditation, so filtration efficiency, dust holding capacity and resistance can be tested and reported. The company holds ISO 9001, ISO 14001 and ISO 45001 certification and obtained IATF 16949 in 2024; products meet REACH and RoHS requirements and compliance documents can be supplied. More than 1000 filter solutions have been developed to date, supporting size, structure, media grade and packaging customisation. The company is based in Zhongshan, Guangdong, China.
To quote accurately, send us the device or vehicle model the filter fits, the required size or a drawing, the airflow the element must pass, the water conditions and expected run time, and the quantity you plan to order. Our team will respond with a specification matched to your air path. Contact Jyntrel to start the selection.
Yes. The dense pleating spreads the wetted surface across the full cylinder wall, so evaporation is distributed rather than concentrated at one face. Tell us the rated airflow so the pleat density can be matched to your fan's pressure budget.
We need the rated airflow of the device, the space available around the fan intake, the cylinder height your housing allows, and the water hardness in the target market. With those inputs we can propose diameter, pleat count and web grade.
The media is designed to retain calcium and magnesium ions within the wetted structure, which limits the mineral load carried into the air as white dust. An antibacterial coating can be added where the market requires it.
Yes. Outer diameter, inner diameter, height, pleat count and optional antibacterial coating are all made to your device drawing, and packaging can be customised for your brand.
The standard MOQ is 1,000 PCS; customised models are quoted according to tooling and material. Production lead time is generally 25–35 days after deposit, with advance planning available for peak-season or large orders.
Under normal household use of about 8 hours per day, the recommended replacement interval is 3–6 months, depending on local water hardness and usage frequency. Rinsing with clean water removes surface mineral deposits; chemical cleaners are not recommended.
Standard samples are provided free of charge to B2B customers, with freight collect. Customised samples are usually completed within 7–10 working days after the drawing and specification are confirmed.
Send the device model, size or drawing, airflow, water conditions and planned quantity through our contact page. Our engineers will return a matched specification and quotation, so <a href="/en/contact">contact Jyntrel</a> to begin.
