This is a circular HEPA filter element for handheld vacuums and robot cleaners, built by Ranveth around a paired media stack: a PTFE microporous membrane over composite PP meltblown, or an antibacterial filter paper where the application calls for it. It captures PM2.5, dust mites, pollen and hair before exhaust air leaves the bin, and its high-porosity build keeps resistance low so motor load and battery drain stay in check. It is aimed at vacuum OEMs and aftermarket brands that need a drop-in or custom-sized round filter with stable efficiency and service life.
Every round filter starts with the same question: which media combination gives the efficiency you need without asking the motor to work harder than it should? The pairing we use most often is a PTFE microporous membrane laminated to a PP meltblown substrate. The membrane does the fine capture at the surface; the meltblown layer underneath holds dust and spreads airflow evenly. Because the membrane releases dust readily, the filter can be washed and reused, and resistance stays low across the service interval. Where the brief calls for a dry-only element, we build with antibacterial-treated filter paper instead.
The layer stack is only half the design. A round filter lives inside a specific bin and airflow path, so the outer frame and edge seal decide whether the media actually performs. We mould the frame to the device geometry in environmentally friendly injection material and finish the edge with a rubber sealing ring, so the element seats with full airtightness and dust does not bypass the media. Diameter, thickness and pleat count are set per device, which is why the same media can deliver different efficiency, resistance and life figures from one platform to the next.
The practical result for a buyer is a filter whose media and structure are chosen together. A denser pleat pack raises dust hold-up but can raise resistance; a more open pack protects airflow but shortens the interval between cleans. Ranveth tunes that balance against the vacuum's airflow and bin volume rather than supplying a generic disc.
| Item | Detail |
|---|---|
| Product name | Vacuum cleaner filter element / robot vacuum filter |
| Core filter media | High-precision PTFE microporous membrane / composite PP meltblown / antibacterial-treated filter paper |
| Core purification function | Captures fine particles (PM2.5), dust mites, pollen and hair inside the dust bin, preventing secondary exhaust pollution |
| Physical and fluid characteristics | High-porosity, breathable design with very low operating resistance and high dust-holding capacity; helps prevent motor overheating and supports battery runtime |
| Main end applications | Handheld cordless vacuums, smart robot vacuums, mattress mite removers, wet-dry floor cleaners, car mini vacuums |
| Frame and size customisation | 100% built to the device airflow path and dust-bin dimensions; environmentally friendly injection-moulded frame with rubber sealing ring edge for airtight, dust-tight seating |
| Company certification systems | 50,000 m² production base and a CNAS-accredited testing centre; ISO 9001, ISO 14001 and IATF 16949 quality management systems |
Round elements of this type sit in handheld cordless vacuums, smart robot vacuums, mattress mite removers, wet-dry floor cleaners and car mini vacuums. The common thread is a compact bin and a short exhaust path, where a flat or poorly sealed filter would either choke airflow or let fine dust back into the room. The PTFE-coated version suits owners who rinse filters between replacements; the paper version suits sealed, dry-only bins.
To quote a custom round filter accurately, we need the device model, the filter diameter and thickness or an existing drawing or sample, the vacuum's airflow figure, the operating conditions (dry dust only or occasional wet pickup, typical dust load), and the order quantity. Send those five items and we can confirm media grade, pleat count and frame geometry before sampling.
Media choices here are test-backed: our in-house laboratory is CNAS-accredited and can issue reports on filtration efficiency, dust-holding capacity and resistance, so the pairing on your drawing is checked against data rather than assumption. Production runs in a 50,000 m² plant that includes six cleanrooms totalling 20,000 m². The factory holds IATF 16949, awarded in 2024, alongside ISO 9001, ISO 14001 and ISO 45001. Products meet REACH and RoHS requirements, and compliance documents can be supplied. Ranveth has more than 20 years of filter development and manufacturing experience, with continuous export to Europe, the US, Japan and Korea over that period. The company is located in Zhongshan, Guangdong, China.
To move a round filter project forward, tell us the device or vehicle model, the size or a drawing, the airflow or water flow, the operating conditions and the quantity you expect. We will reply with a media recommendation and a quotation. Contact Ranveth with your specifications.
The standard build pairs a PTFE microporous membrane with a composite PP meltblown substrate; an antibacterial-treated filter paper is available for dry-only applications. The membrane provides fine particle capture at the surface while the meltblown layer holds dust and distributes airflow. This pairing is what keeps resistance low and allows the washable version to be rinsed and reused.
The standard round HEPA element reaches H11–H13 efficiency, with filtration efficiency of ≥99.95% for 0.3 μm particles. That covers dust, pollen, mites, pet hair and PM2.5. Because media and pleat pack are paired to the device, the exact figure for your model is confirmed against the airflow path during sampling.
Yes. Diameter, thickness and pleat count are set to your drawing or sample, and the frame is injection-moulded to the device's airflow path and dust-bin dimensions with a rubber sealing ring for airtight seating. Media grade, frame material, logo and packaging can all be specified. Sampling typically takes 7–15 days.
Send the device model, filter size or drawing, vacuum airflow, operating conditions and expected quantity. We will confirm the media pairing and return a quotation. Sample and quotation terms for this product are confirmed with that request so the offer matches your specification.
The standard MOQ for this circular filter is 3,000 pieces; custom tooling projects typically start at 5,000 pieces. Standard lead time is 25–35 days after order confirmation. Larger or peak-season volumes are scheduled in advance.
In typical household use the replacement interval is 3–6 months. The PTFE-coated version is washable and can be rinsed and reused for 6–12 months; the paper version is for dry-only, non-washable use. The choice depends on your market positioning, and usage guidance is printed on the packaging and instructions.
Our CNAS-accredited laboratory can test filtration efficiency, dust-holding capacity and resistance on the finished element, and production follows IQC, IPQC and OQC stages. The plant holds IATF 16949 (2024) plus ISO 9001, ISO 14001 and ISO 45001. Products meet REACH and RoHS, with compliance documents available on request.
