The Jyntrel cylindrical humidifier filter (water spray type) is a pleated, cylindrical evaporative wick that draws water upward by capillary action and releases it into the airstream passing through its core. It filters and conditions the water path rather than the air itself, holding back calcium and magnesium ions that would otherwise carry through as white dust, while the pleated honeycomb wall provides a large evaporation surface. It is built for residential cold-evaporation (no-mist) humidifiers, air purifiers with a humidifying stage, and constant-temperature and constant-humidity equipment used in commercial and industrial settings.
Placement in the system determines how the cylinder behaves, so we start from the air path. In a typical installation the cylinder stands in a water trough, partially submerged, and the fan draws air through the open core or across the outer pleat face. Air velocity through the media should be moderate and even; a high face velocity raises the risk of carry-over droplets and shortens the dwell time available for evaporation. A lower, steady velocity through a larger pleat area gives more complete saturation per pass.
Water quality is the second operating variable. Hard water accelerates scale loading on the humidifier paper or polymer humidifier fiber and gradually reduces capillary uptake. The filter is designed to intercept calcium and magnesium ions so they stay in the wick instead of becoming airborne white powder, but the loading rate still follows the water hardness and the hours of daily use. Long soaking is normal in this application, and the pleated structure is made with high wet stiffness so the cylinder keeps its shape in the trough instead of softening, collapsing or shedding pleats. Treated, softened or demineralised water extends service life where the installation allows it.
Temperature and air cleanliness also matter. The wick is intended for the normal operating range of evaporative humidification equipment, not for hot or condensing exhaust streams. Pre-filtering dust ahead of the humidifying stage keeps the pleat surface open and protects the capillary channels.
Performance rests on three properties. The first is strong capillary action: the humidifier paper or polymer fiber lifts water quickly through the pleat wall and releases it readily at the surface, so output responds soon after the pump or trough fills. In the referenced test conditions the humidification efficiency reaches 85% or more, with the exact figure depending on airflow, water temperature and pleat geometry.
The second is a long-life antimicrobial and anti-mould treatment. Standing water is where odour and slime begin, so the media can be supplied with an antimicrobial finish that suppresses bacterial and mould growth and helps prevent the sour, musty smell associated with stale tanks. The third is wet stiffness: the densely pleated honeycomb construction gives a large evaporation area while keeping the cylinder rigid during prolonged immersion, so it does not sag into the water or come apart at the pleat folds.
Jyntrel manufactures this humidifier filter to drawing, with 100% OEM customisation of the cylinder. Outer diameter, inner diameter, height and pleat count are all made to order, and the antimicrobial coating can be specified or omitted. Because fit is dimensional, the fastest route to an accurate quotation is a drawing or a measured sample; where neither exists, the outer diameter, inner diameter, height and the space available in the water trough are enough to begin.
For performance matching, tell us the airflow the fan delivers through the humidifying stage and the expected air velocity at the media face, the water source and hardness, the water temperature, and whether the unit runs continuously or intermittently. Quantity and packaging requirements complete the picture. Send these details through the contact page and our team will confirm feasibility and lead time.

In each case the selection logic is the same: match the cylinder to the housing, then match the pleat area to the airflow the fan can deliver without excessive face velocity.
Supply stability is the first consideration for a consumable wick. Multiple automated production lines at Jyntrel can reach an output of several million pieces per month, and more than 20 years of continuous export to Europe, the United States, Japan and Korea have built the scheduling discipline that repeat orders depend on. The production base covers 50,000 m², including six clean workshops totalling 20,000 m².
Quality is verified in our own laboratory, which holds CNAS accreditation and can issue test reports for filtration efficiency, dust holding capacity and resistance. The company operates ISO 9001, ISO 14001 and ISO 45001 systems and has held IATF 16949 automotive quality certification since 2024. Products meet REACH and RoHS requirements and compliance documents are available on request. IQC, IPQC and OQC checks run across the production flow. The company is based in Zhongshan, Guangdong, China.
To quote this cylindrical humidifier filter accurately, send us the device or vehicle model it fits, the cylinder size or a drawing, the airflow through the humidifying stage, the water source and operating temperature, and the quantity you expect per order. With those details we can propose a pleat configuration, confirm whether an antimicrobial coating suits your water conditions, and return a solution-oriented quotation. Start the conversation on our contact page.
The wick performs best at a moderate, even face velocity. At high velocity the dwell time for evaporation shortens and the risk of carry-over droplets rises. If your fan delivers a high airflow, we size a larger pleat area or a taller cylinder so velocity at the media stays within a workable range.
Tell us the airflow through the humidifying stage and the expected velocity at the media face, plus the fan type and whether operation is continuous or intermittent. Water hardness, water temperature and trough dimensions complete the picture. With these we can propose pleat count and cylinder height.
Under the referenced test conditions the cylindrical humidifier filter reaches 85% or more humidification efficiency. The actual figure in your unit depends on airflow, water temperature and pleat geometry, so we confirm the expected value against your operating data before quoting.
Yes. Jyntrel offers 100% OEM custom manufacturing of outer diameter, inner diameter, height and pleat count, and the antimicrobial coating can be specified or omitted. Send a drawing or a measured sample and we manufacture to those dimensions.
Samples are available for evaluation, and our CNAS-accredited laboratory can supply performance test reports covering key indicators with the sample. Sample arrangements and any charges are confirmed at quotation stage based on your specification. Use the contact page to request one.
Minimum order quantity depends on the specification and whether the cylinder is standard or fully customised. Share your dimensions and expected annual volume and we will state the MOQ for your exact configuration in the quotation.
Lead time follows the specification and order quantity, with custom tooling and sampling adding time before mass production. Once dimensions and quantities are confirmed we issue a schedule with the quotation. Long-term programmes can be planned with repeat-order scheduling.
Under standard operating conditions the service life is 6 to 12 months, depending on water quality and hours of use. Hard water and continuous running shorten it; softened or demineralised water extends it. Replace when output falls or odour returns, and contact us to set a replacement cycle for your unit.
