This is a cylindrical washable HEPA filter designed for handheld and robot vacuum cleaners. It captures PM2.5, dust mites, pollen and hair from the dust box, preventing secondary pollution from exhaust air. It is intended for vacuum manufacturers, aftermarket brands and OEM/ODM partners who need reliable filtration with low airflow resistance. The brand is Oltaven.
A filter is not just a sheet of media. The finished performance comes from how the media is pleated, framed and sealed. At Oltaven, we start with high-precision PTFE membrane, composite PP meltblown or antibacterial filter paper, then form it into a cylindrical or conical shape that fits the vacuum's airflow path. The pleat count, pleat depth and pleat spacing determine the effective surface area inside the available space. The frame and rubber sealing ring ensure 100% airtightness so dust does not bypass the filter. Our engineering team develops each filter as a complete component, ready to drop into your device.
Media choice sets the baseline efficiency. PTFE membrane offers fine micropore interception for particles as small as PM2.5, while PP meltblown provides high dust-holding capacity. Antibacterial treatment can be added for hygiene-sensitive applications. But the same media can perform very differently once formed. A pleat pattern that is too tight raises pressure drop; one that is too loose reduces capacity. The frame material and sealing method affect both durability and leakage. That is why we sell finished filters, not just media. Every design is validated as a system.
Three factors decide how a finished filter performs in a vacuum: efficiency, resistance and capacity. Efficiency is governed by the media's pore size and the integrity of the seal. Our washable HEPA filters can achieve H11 to H13 efficiency (≥95% to ≥99.95% for 0.3 μm particles), depending on customer requirements. Resistance, or airflow resistance, is influenced by pleat geometry and media permeability. The high-porosity design in our filters keeps resistance low, which helps maintain motor suction and extend battery runtime. Capacity is the amount of dust the filter can hold before cleaning; it depends on pleat depth, media loft and the uniformity of pleating.
Forming also matters for washability. The PTFE membrane is treated to withstand repeated rinsing. After correct cleaning and complete drying, the filter typically endures 20–30 wash cycles with limited performance decay. The frame and sealing ring are designed to hold their shape through these cycles, preserving airtightness. Each batch is tested in our CNAS-accredited laboratory for efficiency, resistance and capacity, so the finished filter matches the specification.
These cylindrical filters are used in handheld wireless vacuums, smart robot vacuums, mattress mite removers, wet-dry floor cleaners and car mini vacuums. They are compatible with popular brands such as Dyson, Shark, Bissell, Xiaomi and Kingclean, but we also produce custom shapes for new device designs. Because we control the entire forming process, we can adapt the filter to fit specific dust box geometries, airflow paths and motor requirements.

Resistance depends on pleat geometry, media permeability and seal integrity, not just outer dimensions. A filter with deeper, more uniform pleats has more surface area and lower resistance. Our design optimises these factors to keep airflow resistance low and maintain motor suction.
Our washable HEPA filters can achieve H11 to H13 efficiency (≥95% to ≥99.95% for 0.3 μm particles), depending on your requirements. After correct washing and complete drying, they typically withstand 20–30 wash cycles with limited performance decay. All performance data are verified in our CNAS-accredited laboratory.
It starts with your requirements: device model, target efficiency, airflow resistance limits and annual volume. We then propose a design, produce samples for your validation, and after approval move to tooling and mass production. Our team supports you through each step.
Yes. We offer 100% customisation of frame and dimensions based on your device's airflow path and dust box. This includes filter diameter, height, pleat count, end-cap structure and sealing ring material. Provide a sample or drawing and we will develop a matching filter.
For custom molded products, MOQ typically starts at 5,000 pieces, depending on specifications. Standard orders are delivered 25–35 days after order confirmation. We recommend confirming production schedules early during peak seasons or for large volumes.
Yes. We provide stock samples free of charge; you only cover international shipping. Custom samples incur a sampling fee based on tooling complexity, which is refundable after mass production. Sample lead time is 3–7 days for stock and 15–20 days for custom.
Our filters comply with REACH and RoHS environmental regulations, and we can provide compliance documents. The company holds ISO 9001, ISO 14001, ISO 45001 and IATF 16949 certifications. We have exported to Europe, the US, Japan and South Korea for over 20 years.
Replacement interval depends on usage and cleaning frequency. With regular washing (typically every 2–4 weeks) and complete drying, the filter can last 20–30 wash cycles. After that, efficiency may decline, and we recommend replacement to maintain performance.
