The Jyntrel cylindrical HEPA filter is a 360° pleated cartridge that captures fine dust and allergens from the air stream in household air purifiers, commercial fresh-air units, vehicle cabins and high-end vacuums. It is built for OEM and ODM programmes that need a defined efficiency class and a housing-matched footprint. The filter media are high-flux PP, PP+PET composite nonwoven and PTFE, selected to suit the duty cycle of your device.
Air enters the cylindrical filter radially through the full 360° surface and passes through the pleated media before leaving via the open core. Because the entire circumference is active, face velocity is kept low relative to the airflow, which supports a higher clean air delivery rate (CADR) in compact purifier housings. The media pack is chosen to balance initial resistance against the pressure budget of your fan curve.
In new-air systems, the filter sees steady airflow for long periods, so dust-holding capacity drives replacement intervals. In vehicle and portable appliances, airflow is intermittent and vibration is present; a robust pleat pack and bonded end construction help maintain shape under those cycles. For environments with coarse debris, an upstream pre-filter layer can be combined to shield the HEPA media and extend service life.
Relative humidity and temperature should be checked against the media selected. PTFE media are suited to humid air streams, while PP and PP+PET composites are typically used in dry indoor air. Share the operating envelope with our engineers so the construction can be matched to the application.
Efficiency is customisable from medium-efficiency grades up to HEPA class, with standard coverage from H11 to H14 and up to 99.995% filtration efficiency for 0.3 μm particles. The 360° design increases the usable filtration area, which raises CADR and dust-holding capacity, so replacement frequency can be reduced in comparable housings. All filters are tested at our CNAS-accredited laboratory for efficiency, resistance and dust-holding capacity, and test reports can be supplied with the order.
Because every appliance cavity is different, the cylindrical filter is made to order in any diameter and height. To recommend the right media and pleat geometry, we ask for the following:
With these inputs, Jyntrel can propose a construction and provide samples for bench testing before production tooling is committed.
| Item | Detail |
|---|---|
| Product name | Cylindrical HEPA Filter for air purifiers |
| Materials | High-flux PP, PP+PET composite nonwoven, PTFE |
| Filtration efficiency | Customisable from medium-efficiency to HEPA grade, effectively removing fine dust and allergens |
| Structure | 360° cylindrical design; inner or outer pre-filter mesh or activated carbon layer can be combined as required |
| Dimensions | Fully customisable; any diameter and height to suit the purifier cavity |
| Applications | Household air purifiers, commercial fresh-air systems, vehicle air purifiers, high-end vacuum cleaners |

The filter is used in household air purifiers where a compact cartridge must deliver high CADR, in commercial fresh-air systems that require a defined HEPA stage, in vehicle air purifiers where vibration resistance matters, and in high-end vacuum cleaners where fine dust retention is critical. It can also be specified for laboratory equipment and electronics workshops when the efficiency class and airflow are matched to the installation.
Jyntrel operates multiple automated production lines with a monthly capacity of millions of pieces, backed by more than 20 years of export experience to Europe, the United States, Japan and Korea. The 50,000 m² plant includes six clean rooms totalling 20,000 m², where HEPA filters are assembled to limit contamination. Our CNAS-accredited laboratory issues test reports for efficiency, dust-holding capacity and resistance, and the factory holds IATF 16949 (2024), ISO 9001, ISO 14001 and ISO 45001. IQC, IPQC and OQC checks run throughout production, and REACH and RoHS compliance documents are available. The company is based in Zhongshan, Guangdong, China.
To receive a tailored solution, please send us your device or vehicle model, the required size or a drawing, the target airflow, the operating conditions and your estimated quantity. Our engineers will respond with a proposed construction and sample plan. Contact Jyntrel to start the conversation.
The 360° cylindrical design spreads airflow over the full circumference, which lowers face velocity for a given airflow and helps maintain low resistance. For high-velocity systems, we select a media and pleat geometry that balances efficiency and pressure drop. Share your airflow and fan curve so we can confirm the suitable construction.
We need the rated airflow or the fan curve of your device, the expected duty cycle, and the available pressure budget. The housing dimensions or a drawing are also required to match the filter footprint. With these inputs we can propose the media grade and pleat count.
Standard coverage ranges from H11 to H14, with up to 99.995% filtration efficiency for 0.3 μm particles. Medium-efficiency versions are also available for pre-filtration or less demanding applications. Each batch is tested at our CNAS-accredited laboratory for efficiency, resistance and dust-holding capacity.
Yes. The filter is fully customisable in diameter and height to suit your purifier cavity, and the media can be PP, PP+PET composite or PTFE. We can also combine a pre-filter mesh or activated carbon layer, and customise end caps, packaging and logos for OEM/ODM programmes.
Standard samples are typically dispatched in 3–5 working days, while custom samples take 7–15 working days. The MOQ for standard cylindrical HEPA filters is usually 1,000 pieces; custom designs are quoted separately. Sample fees can be credited against bulk orders.
Bulk orders are generally delivered in 25–35 days after confirmation, depending on quantity and current production scheduling. We recommend planning ahead during peak season. Our automated lines support a monthly capacity of millions of pieces to help meet repeat demand.
In normal household or commercial use, a replacement interval of 6–12 months is typical. In high-load industrial environments, replacement should be based on pressure-drop monitoring. We can provide dust-holding capacity data to help set a replacement indicator for your device.
Our factory holds ISO 9001, ISO 14001 and ISO 45001, and products meet REACH and RoHS requirements with documentation available. We also hold IATF 16949 and have exported to Europe and North America for over 20 years. Please tell us your target market so we can confirm the relevant files.
