This washable dust box filter is an integrated filter assembly designed for robot vacuums and handheld vacuums. It captures PM2.5, fine dust, dust mites, pollen and pet dander from the airflow, helping prevent secondary contamination from exhaust. It is intended for appliance brands, OEM/ODM buyers and maintenance suppliers who need a custom-fit, reusable filter. The brand is Ranveth.
The filter uses a high-precision PTFE microporous membrane, alone or combined with composite PP meltblown media, to form a moisture-resistant and antibacterial layer build. The pairing is chosen so that the membrane provides fine particle capture while the PP layer supports dust holding and mechanical stability. This combination is what drives the balance between efficiency, airflow resistance and service life.
Because the media is paired for low airflow resistance, the filter helps maintain the vacuum's suction performance and can support battery runtime. The integrated construction means the filter fits directly into the dust box as a single part, and the washable design allows repeated cleaning. The exact layer sequence and media grade are selected per device requirement during custom development.
| Item | Detail |
|---|---|
| Product name | Robot vacuum cleaner / handheld vacuum filter |
| Core filter media | High-precision PTFE (polytetrafluoroethylene microporous membrane) / composite PP (polypropylene meltblown) and other moisture-resistant antibacterial filter materials |
| Core purification function | Strong interception of PM2.5, fine dust, dust mites, pollen and pet dander inside the vacuum; prevents secondary contamination from exhaust |
| Physical fluid characteristics | High-porosity breathable design; very low operating airflow resistance; does not sacrifice motor suction; supports improved battery runtime |
| Main application terminals | Smart robot vacuums, handheld cordless vacuums, bed mite removers, car mini vacuums, wet-dry vacuums |
| Frame and size customisation | 100% customised to the device dust box size. Eco-friendly injection-molded frame, edge overmolding seal, and scale OEM production of washable materials (PTFE-coated version) are available |
| Enterprise certification system | The company has a 50,000 m² modern production base and a CNAS-accredited testing center. It follows ISO 9001, ISO 14001 and IATF 16949 international quality management system standards |
This filter is used in smart robot vacuums, handheld cordless vacuums, bed mite removers, car mini vacuums and wet-dry vacuums. It is suitable for both original equipment and aftermarket programs where a washable, integrated filter is required. Because the filter is customised to the dust box, it can be adapted to different device geometries and suction systems.
To start a custom build, please provide the device or vehicle model, the dust box size or a drawing, the airflow requirement (if known), the operating conditions (such as typical dust load and cleaning frequency), the estimated quantity, and any packaging or branding requirements. Our team will review the information and recommend a media pairing and layer build that fits your performance targets.
Ranveth backs its media choices with testing. The company's in-house laboratory is CNAS-accredited and can issue reports on filtration efficiency, dust holding capacity and airflow resistance. Manufacturing takes place in a 50,000 m² plant that includes six cleanrooms totaling 20,000 m². The company is certified to IATF 16949 (obtained in 2024) and holds ISO 9001, ISO 14001 and ISO 45001 system certifications. Products comply with REACH and RoHS environmental regulations, and compliance documents are available. With more than 20 years of experience in filtration R&D and manufacturing, Ranveth has supplied OEM and ODM customers for over two decades and offers customisation of size, structure, media grade, frame material, logo and packaging.

The filter uses a high-precision PTFE microporous membrane, optionally combined with composite PP meltblown media, to create a moisture-resistant and antibacterial layer build. This pairing is selected to balance fine particle capture with low airflow resistance.
The PTFE membrane provides fine particle capture, while the PP layer supports dust holding and mechanical stability. Together they maintain low airflow resistance, helping preserve suction and battery runtime. The exact layer sequence is customised per device requirement.
Yes, the washable design allows repeated cleaning. The service life depends on usage and cleaning frequency; the filter is intended for multiple cleaning cycles. For specific durability data, please inquire with your operating conditions.
Yes, the filter is 100% customised to the dust box size, with options for frame material, edge sealing, media grade, logo and packaging. Provide your device model and drawing, and we will develop a fitting solution.
MOQ for standard specifications is typically 5,000–10,000 pieces, while customised products are negotiated based on complexity. Please contact us with your requirements for a precise quote.
Sample lead time is 7–15 days for customised samples. Mass production lead time is typically 30–45 days for customised orders, depending on order confirmation. Standard stock items can ship in about 7–15 days.
Under normal household use, the filter can last 6–12 months with regular washing. Replace it if suction drops noticeably or if the filter is damaged. Actual interval depends on usage frequency and dust load.
Yes, we offer free standard samples for evaluation (sample cost may apply depending on model and is typically credited against the first order); international shipping is usually at the customer's expense. Custom samples take 7–15 days. We recommend full installation and performance testing before bulk purchase. Please <a href="/en/contact">contact us</a> to discuss your sample needs.
