FILTER MEDIA / ROLLS · SHEETS · DIE-CUT
This is an integrated washable dust box filter for robot vacuums and handheld vacuums, made with PTFE membrane or composite PP media to capture PM2.5, fine dust, dust mites, pollen and pet dander. It is designed for vacuum manufacturers and brands that need a drop-in or custom filter that keeps airflow high and motor suction strong. Oltaven builds the finished filter, not just the media, so efficiency, resistance and dust capacity are set by how the media is pleated, framed and sealed.
Filter media is only the starting point. A PTFE membrane gives a thin, breathable layer that traps fine particles, while composite PP meltblown adds depth for holding dust. But the same media can feel restrictive or leak dust if the finished filter is built poorly. Pleat height and pleat count decide how much surface area sits inside the dust box. A taller pleat pack with more folds spreads airflow over a larger area, which lowers resistance and raises dust holding capacity. The frame holds the pleat pack flat and prevents bypass. An injection-molded frame with edge sealing keeps air from slipping around the media, so particles are forced through the filter instead of around it. Sealing also matters at the edges: a continuous bond between media and frame stops fine dust from escaping and re-entering the room through the exhaust. At Oltaven we control these steps in-house, so the finished filter delivers the efficiency, low resistance and service life that the media alone cannot guarantee.
Three factors decide how a finished filter performs in a vacuum: media choice, pleat geometry and frame sealing. Media choice sets the baseline efficiency. PTFE membrane media captures fine particles such as PM2.5 and allergens at high efficiency, and it can be washed because the membrane resists clogging. Composite PP media offers good dust holding at a lower cost. Pleat geometry controls resistance and capacity. More pleats and deeper pleats mean more filter area, so air moves through more slowly and the motor does not have to work as hard. This is why a well-pleated filter can keep suction strong even as it loads with dust. Frame sealing controls real-world efficiency. If the frame does not seal against the dust box, air bypasses the media and carries dust back into the room. Oltaven uses injection-molded frames with edge sealing to close that gap. The result is a filter that traps fine dust, keeps airflow high and supports the vacuum's battery runtime by not overloading the motor.
This filter is used in smart robot vacuums, handheld cordless vacuums, bed mite removers, compact car vacuums and wet-dry floor cleaners. Each application has its own dust box shape and airflow pattern, so Oltaven customizes the filter to the device rather than forcing a universal size. For robot vacuums, the filter must fit the dust box exactly and resist clogging from hair and fine dust. For handheld vacuums, low resistance helps maintain suction as the bin fills. For bed mite removers, fine particle capture is the priority. Because the filter is washable, end users can rinse it and reuse it, which lowers replacement cost and waste.

Oltaven is an OEM/ODM filter manufacturer with more than 20 years of experience and over 1,000 developed filtration solutions. Our 50,000 m² plant includes six cleanrooms totaling 20,000 m², which helps keep finished filters free from contamination during production. Our in-house CNAS-accredited laboratory tests filtration efficiency, dust holding capacity and resistance, and can issue reports for each batch. We are certified to ISO 9001, ISO 14001 and ISO 45001, and we added IATF 16949 automotive quality management certification in 2024. Our products meet REACH and RoHS requirements, and we can provide compliance documents for European, American, Japanese and Korean markets. IQC, IPQC and OQC controls run through the whole process, and multiple automated production lines support monthly output in the millions of pieces.
To quote your washable dust box filter, please send the device or vehicle model, size or drawing, airflow or water flow requirement, operating conditions and estimated quantity. Our team will respond with a recommended specification and sample plan. Contact Oltaven to start your OEM/ODM project.
Resistance depends on how the media is pleated and framed, not just the outer dimensions. A filter with more pleats and deeper pleats has more surface area, so air passes through at a lower speed and resistance drops. Frame sealing also matters: if air bypasses the media, resistance may look low but efficiency falls. Oltaven controls pleat geometry and edge sealing to balance low resistance with high efficiency.
An OEM project starts with your device model, dust box size or drawing, airflow target, operating conditions and estimated quantity. Oltaven then recommends media and pleat geometry, builds a sample in 7–15 days, and after your approval confirms MOQ, lead time and packaging for mass production.
The filter uses high-efficiency multi-layer composite media and achieves over 99% filtration efficiency for PM2.5 and fine dust particles, effectively intercepting dust, hair, pollen and common allergens. Each batch is tested in our CNAS-accredited laboratory for efficiency and resistance to ensure stable performance.
Yes. The filter uses washable media and a reinforced structure that supports more than 30 washes with less than 5% performance decay. Under normal household use, it can last 6–12 months, reducing replacement cost and waste for end users.
Standard specifications typically have an MOQ of 5,000–10,000 pieces, while custom products are negotiated based on complexity. Stock orders ship in about 7–15 days; custom orders including mold making usually take 30–45 days, confirmed at order placement.
Yes. We provide free standard samples for qualified B2B customers (sample cost may apply depending on model and is usually credited against the first order), with international express fees typically paid by the customer. Custom samples take 7–15 days and may incur a sampling fee based on mold or customization requirements.
Under normal use, replace the filter every 6–12 months, or more often if the vacuum is used heavily or collects fine dust such as pet dander. The washable design allows rinsing between replacements, but efficiency should be monitored and the filter replaced when suction drops noticeably.
Oltaven holds ISO 9001, ISO 14001 and ISO 45001 certifications, and added IATF 16949 in 2024. Our materials meet REACH and RoHS requirements, and we can provide compliance documents for European, American, Japanese and Korean markets. Contact us to discuss your compliance needs.
