This Zanxis dust box HEPA filter is a washable replacement filter for robot vacuums and handheld vacuums, made with PTFE membrane or composite PP meltblown media to capture PM2.5, fine dust, dust mites, pollen and pet dander. It is designed for vacuum manufacturers, aftermarket brands and OEM buyers who need low-airflow-resistance filtration that preserves suction and battery runtime. The filter is fully customised to the dust box dimensions of each device, with injection-moulded frames and edge sealing available.
| Item | Detail |
|---|---|
| Product name | Robot vacuum filter / handheld vacuum filter |
| Core filtration material | High-precision PTFE (polytetrafluoroethylene microporous membrane) / composite PP (polypropylene meltblown) and other moisture-resistant antibacterial media |
| Core purification function | Effectively intercepts PM2.5, fine dust, dust mites, pollen and pet dander inside the vacuum, preventing secondary pollution from exhaust air |
| Physical fluid characteristics | High-porosity breathable design with very low operating airflow resistance, preserving motor suction and improving device battery endurance |
| Main end applications | Smart robot vacuums, handheld cordless vacuums, mattress mite removers, car mini vacuums, wet-dry floor cleaners |
| Frame and size customisation | 100% customised to the device dust box dimensions. Eco-friendly injection-moulded frames, edge rubber sealing, and scalable OEM production of washable materials (PTFE-coated versions) |
| Company certification system | 50,000 m² modern production base and a national CNAS testing centre. Strictly implements ISO 9001, ISO 14001 and IATF 16949 international quality management system standards |
Before a sample is built, confirm the filtration efficiency grade you require. The filter media can be specified to H11–H13 levels, corresponding to ≥95%–99.97% filtration efficiency for 0.3 μm particles. Confirm the airflow resistance your device can tolerate, because the high-porosity design is intended to keep resistance low and protect suction and battery runtime. Confirm the dust box interface dimensions and the frame type: injection-moulded frame with edge sealing is available, and the washable PTFE-coated version should be specified if repeated washing is part of your use case. Also confirm whether the filter will be used in a robot vacuum, handheld vacuum, mite remover, car vacuum or wet-dry cleaner, as this affects the mechanical fit and media choice.
The filter is built around a high-porosity filtration layer that traps fine particles while keeping airflow resistance low. PTFE membrane versions are moisture-resistant and washable, while composite PP meltblown versions suit standard dust box applications. The frame is injection-moulded to the dust box profile, with edge rubber sealing to limit bypass. Because the filter is fully customised to the device, it can be adapted to robot vacuums, handheld cordless vacuums, mattress mite removers, car mini vacuums and wet-dry floor cleaners. For washable versions, the recommended service life is 3–6 months depending on use frequency, and the filter can be washed repeatedly within the rated wash cycles. The low-resistance design is intended to preserve motor suction and support battery endurance in cordless devices.
Zanxis operates a self-built laboratory accredited by CNAS (China National Accreditation Service for Conformity Assessment), which can issue test reports for filtration efficiency, dust holding capacity and resistance. The production base covers 50,000 m², including 6 clean workshops totalling 20,000 m². The company has held IATF 16949 automotive quality management system certification since 2024, and also holds ISO 9001, ISO 14001 and ISO 45001 system certifications. Products comply with REACH and RoHS environmental regulations, and compliance documents can be provided. Quality control runs through IQC incoming inspection, IPQC in-process inspection and OQC outgoing inspection. With more than 20 years of filtration product development and manufacturing experience, Zanxis has supplied OEM/ODM filter solutions to customers in Europe, the United States, Japan and South Korea, and has developed more than 1,000 filtration solutions. Multiple automated production lines support monthly capacity in the millions of pieces. The company is located in Zhongshan, Guangdong, China.
To receive a sample and the corresponding test report, please provide your device or vehicle model, the dust box size or a drawing, the required airflow or suction specification, your operating conditions (including whether the filter will be washed), and your estimated quantity. Send these details through our contact page at /en/contact and the team will respond with a specification proposal and sampling plan.
Yes. Zanxis has a CNAS-accredited laboratory that can issue test reports covering filtration efficiency, dust holding capacity and resistance. These reports are generated from samples built to your specification. Contact us with your device model and required efficiency grade to request the relevant report.
Standard samples are produced in 3–7 working days, while tooling-based custom samples take about 10–15 working days. After you receive the sample, laboratory testing and your own fit and suction checks add further time depending on your internal process. We recommend confirming the specification before sampling to avoid repeated rounds.
The filter media can be specified to H11–H13 grades, which correspond to ≥95%–99.97% filtration efficiency for 0.3 μm particles. The exact grade is selected according to your device requirements and confirmed during sample validation. Efficiency is verified in the CNAS-accredited laboratory.
Yes. The filter is 100% customised to the dust box dimensions of each device, with injection-moulded frames and edge rubber sealing available. We can work from your drawing or a physical sample to achieve a 1:1 fit. Customisation also covers media grade, frame material, logo and packaging.
For standard specifications, the MOQ is typically 5,000–10,000 pieces, while customised products are negotiated according to complexity. Standard stock orders ship in about 7–15 days; customised orders including tooling usually take 30–45 days after confirmation. Please confirm the exact MOQ and lead time for your specification with our team.
Under normal use, the recommended service life is 3–6 months depending on use frequency. The washable PTFE-coated version can be washed repeatedly within the rated wash cycles, and filtration efficiency decay is controlled within 5% within the specified wash count, as verified by laboratory testing. Replace the filter when suction drops noticeably or the media shows damage.
Yes. For standard models we can provide 1–3 samples free of charge with freight collect; customised samples are subject to a sampling fee that can be credited against a bulk order. Sampling typically takes 3–7 working days for standard items. Please share your device model and requirements to start the sample request.
