This is a washable disc-shaped filter for handheld vacuum cleaners, robot vacuums and similar machines, made by Oltaven. It captures PM2.5, fine dust, dust mites, pollen and pet dander before air leaves the dust cup, so exhaust air does not carry particles back into the room. It is built for vacuum makers, robot vacuum brands and private-label sellers who need a finished filter matched to their machine, not a roll of media. The filter combines high-precision PTFE microporous membrane, composite PP meltblown or antibacterial-treated filter paper with a moulded frame and sealing edge.
Media is only the starting point. A finished vacuum filter is the result of four decisions that interact: which medium is chosen, how it is pleated, how it is framed, and how it is sealed against the housing. Oltaven sells the finished part, which means we take responsibility for all four.
The medium sets the ceiling on efficiency and the floor on resistance. PTFE microporous membrane gives fine particle capture and can be washed; composite PP meltblown offers a different balance of airflow and cost; antibacterial-treated paper suits applications where odour and microbial growth matter. None of these performs in a vacuum until it is formed.
Pleating decides how much medium fits into the available disc area. More pleats and deeper pleats add surface area, which raises dust holding capacity and slows the rise in resistance as the filter loads. The pleat pattern also affects how evenly air passes through the medium; uneven flow concentrates dust in one zone and shortens service life. Framing and sealing then determine whether air actually goes through the medium or leaks around it. A frame that does not close the gap to the housing lets dust bypass the filter entirely, no matter how good the medium is.
Efficiency comes from the medium grade and from the integrity of the seal. The PTFE membrane and fine fibre layers intercept particles in the PM2.5 range and smaller, including allergens such as dust mite debris, pollen and pet dander. Sealing quality protects that efficiency in the machine: the moulded frame and rubber sealing edge are designed to close the airflow path so dusty air cannot slip past the filter.
Resistance is set by the medium's pore structure, the pleat density and the open area of the frame. A high-porosity, breathable design keeps operating resistance low, which matters in a battery-powered vacuum: lower resistance means the motor is not working against a choked filter, suction is preserved and runtime is not wasted. It also helps limit motor heating.
Capacity is the amount of dust a filter holds before resistance rises too far. Pleat count, pleat depth and disc diameter all contribute. The PTFE medium is washable, so the filter can be cleaned and returned to service rather than replaced after every heavy clean. Washability depends on the medium surviving rinsing without losing its pore structure, which is why the membrane choice and the bonding of the pleat pack to the frame are decided together.
Fit is a performance parameter, not a cosmetic one. Diameter, thickness, centre hole and frame shape must match the machine's filter chamber. Oltaven moulds frames in cylinder, flat and special shapes to the equipment's dimensions, with rubber sealing rings where the design calls for them, to support airtight seating.
In each case the same principle applies: the filter is matched to the machine's airflow and chamber geometry, so the motor keeps its suction and the exhaust stays clean.

Oltaven supports OEM and ODM programmes and has developed more than 1,000 filtration solutions. That range is useful when a new vacuum design needs a filter shape that does not yet exist in a catalogue.
The manufacturing base covers 50,000 m² in Zhongshan, Guangdong, China, including six cleanrooms with a combined area of 20,000 m². A CNAS-accredited laboratory can issue test reports covering filtration efficiency, dust holding capacity and resistance, so performance claims can be documented.
Quality management follows ISO 9001, ISO 14001 and ISO 9001, ISO 14001 and ISO 45001, and the company was certified to IATF 16949 in 2024. Products meet REACH and RoHS requirements, and compliance documents can be supplied. Multiple automated production lines support output of millions of pieces per month, and IQC, IPQC and OQC checks run through the process. Oltaven has more than 20 years of filtration R&D and manufacturing experience and has exported to Europe, the United States, Japan and Korea for over 20 years.
To quote accurately we need the device or vehicle model, the size or a drawing, the airflow or water flow the machine moves, the operating conditions, and the quantity you expect per order and per year. Send these details through the contact page and our team will respond with a proposal. We welcome long-term OEM and ODM partnerships and will work from your sample or drawing to a production-ready washable disc filter.
Efficiency comes from the high-precision PTFE microporous membrane or composite PP meltblown media, which intercepts PM2.5, fine dust, dust mites, pollen and pet dander. The moulded frame and rubber sealing edge keep air flowing through the medium rather than bypassing it. Efficiency and resistance data can be documented by the CNAS-accredited laboratory.
Resistance depends on the medium's pore structure, the pleat count and depth, and the open area of the frame, not on the outer diameter alone. A high-porosity breathable design keeps operating resistance low so the motor retains suction. Two discs can share a diameter and still behave differently in the same vacuum.
Yes. Oltaven offers 100% structural and dimensional OEM customisation: disc diameter, thickness, centre hole, frame shape (cylindrical, flat or special), frame colour and rubber sealing ring edging. Send a drawing or a sample filter and we will match the geometry to your filter chamber.
The project starts with your device model, a size or drawing, the airflow the machine moves, the operating conditions and your expected quantity. Oltaven then proposes the medium grade, pleat pattern and frame, builds samples and verifies performance before production. Reach us through the contact page to begin.
Standard specifications typically start at 3,000 pieces, and custom tooling projects generally start at 5,000 pieces, with the exact figure depending on the specification. Stock samples can be supplied free of charge with freight paid by the customer; custom samples carry a small development fee that can be credited against the first mass-production order. Typical lead time is 25–35 days after order confirmation.
The PTFE medium is washable, so the filter can be rinsed and reused through many cleaning cycles before replacement. Replacement timing depends on dust load and cleaning habits; we recommend replacing it when suction drops noticeably after washing or when the medium is damaged. This reduces the end user's replacement cost.
Oltaven holds ISO 9001, ISO 14001 and ISO 45001 certification and was certified to IATF 16949 in 2024. Materials meet REACH and RoHS requirements and compliance documents can be provided. Testing is carried out in the company's CNAS-accredited laboratory, which can issue efficiency, dust holding capacity and resistance reports.
