The Oltaven washable dust box filter is a removable filter for robot vacuums and handheld vacuums that captures fine dust, mites, pollen and pet dander before air returns to the room. It combines high-precision PTFE membrane or composite PP meltblown media with a custom-molded frame, and is made for vacuum makers and brands that need a washable, low-resistance filter matched to their dock or dust box. Oltaven supplies the finished filter, not just the media.
A filter’s job starts with the media, but it does not end there. The same PTFE membrane or composite PP meltblown sheet can behave very differently once it is pleated, framed and sealed. Pleating increases surface area so air can pass at lower speed; framing holds the pleats in shape and fits the dust box; sealing prevents air from bypassing the media. Each step changes efficiency, resistance and dust capacity in the finished part.
Oltaven’s approach is to treat these steps as one system. We select a media grade for the target particle size and airflow, then design the pleat count and frame geometry around the device’s dust box. The result is a finished filter that keeps suction strong, holds more dust before cleaning, and can be washed without losing its structure. Because we manufacture the finished filter, we can adjust the media, pleating and frame together rather than forcing a device to accept an off-the-shelf part.
Three factors decide how a finished filter performs: media choice, pleat and frame design, and sealing quality. Media choice sets the baseline for what the filter can capture. PTFE membrane offers fine pore control for micro-dust and allergens; composite PP meltblown provides high porosity and moisture resistance. Neither is automatically better — the right choice depends on the particle size, airflow and washing routine of the device.
Pleat and frame design decide resistance and capacity. More pleats mean more area and lower air speed through the media, which helps preserve suction and battery runtime. A frame that fits the dust box precisely keeps the filter in place without gaps. Sealing quality decides whether air actually goes through the media or slips around it. Even a high-efficiency media loses value if the frame does not seal. Oltaven controls these variables in-house, from pleat spacing to frame molding and edge sealing, so the finished filter matches the device’s airflow path.
These filters are used in smart robot vacuums, handheld cordless vacuums, bed mite removers, portable car vacuums and wet-dry floor cleaners. In each case, the filter protects the motor and stops fine dust from returning to the room. Because the filter is removable and washable, users can clean it instead of replacing it frequently, which reduces consumable waste. Oltaven customizes the outer frame and dimensions to the device’s dust box, and can supply injection-molded frames with edge sealing for a precise fit.

Oltaven supports OEM and ODM projects and has developed more than 1,000 filtration solutions. Our 50,000 m² plant includes six cleanrooms totaling 20,000 m², where filters are made in a controlled environment. The in-house laboratory is CNAS-accredited and can issue test reports on filtration efficiency, dust capacity and resistance. We have held IATF 16949 since 2024 and also operate ISO 9001, ISO 14001 and ISO 45001 systems. Products meet REACH and RoHS requirements, and compliance documents are available. With more than 20 years of filtration manufacturing experience, we have exported to Europe, the United States, Japan and South Korea for over two decades.
To quote a washable dust box filter for your device, please tell us the device or vehicle model, the dust box size or a drawing, the airflow or water flow (if applicable), the operating conditions, and the quantity you need. Send these details through our contact page and our team will respond with a proposal. We welcome OEM and ODM partnerships and can support projects from sample to mass production.
Resistance depends on media choice, pleat count and sealing quality, not just outer dimensions. A filter with more pleats has more surface area, so air moves more slowly through the media and resistance stays lower. Oltaven adjusts these variables together so the finished filter preserves suction in your device.
Pleating increases the media area, which lowers air velocity and helps capture fine particles without high resistance. Framing and edge sealing keep air flowing through the media rather than around it. If the frame does not seal well, efficiency drops even with good media. Oltaven controls pleat spacing, frame molding and edge sealing in-house to keep efficiency and fit consistent.
Yes. We customize the outer frame and dimensions to your dust box size, and can supply injection-molded frames with edge sealing. Provide a drawing or sample and we will propose a filter structure and media grade. Custom sizes and structures are part of our OEM/ODM service.
An OEM project starts with your device model, dust box size or drawing, target airflow and operating conditions. We then propose a media and frame design and produce samples. Sample lead time can be about 7 days after details are confirmed.
MOQ for standard specifications is typically 5,000–10,000 pieces; custom products are quoted based on complexity. Lead time for standard items is about 7–15 days, and custom orders including tooling are typically 30–45 days after confirmation. Our automated lines can reach monthly capacity of millions of pieces to support repeat orders.
With correct washing, the filter can be washed more than 50 times while filtration efficiency remains above 90% of its initial value, as verified by our CNAS-accredited laboratory. Replacement depends on use and washing habits; we recommend replacing it when suction drops noticeably or the media shows damage. The removable design makes cleaning easy and extends service life.
Our filters meet REACH and RoHS requirements, and compliance documents are available. The materials are moisture-resistant and antibacterial.Please contact us for specific compliance needs for your market.
