The Oltaven MAX Series flat panel HEPA filter is a finished, ultra-thin pleated filter built for air purifiers, compact purifiers, humidifying purifiers, dehumidifiers and robot vacuum exhausts. It captures submicron particles, with efficiency determined by the media grade selected, from E11 up to H14/U15. It is made for appliance makers and brands that need a low-resistance, space-saving filter in custom sizes. Oltaven supplies the finished filter, not just the media.
A HEPA filter begins as media, but its finished performance is decided by how that media is pleated, framed and sealed. The MAX Series uses PP meltblown, PP+PET composite moisture-resistant material or PTFE membrane as the core media. Each has a different balance of efficiency, airflow resistance and dust-holding capacity, and each behaves differently once it is formed into a panel.
Pleating creates the surface area that lets air pass through at low resistance while holding more dust. Framing holds the pleat pack in shape and fits the filter into the appliance. Sealing closes the edges so air cannot bypass the media. Oltaven sells finished filters because these forming steps, not the media alone, determine what the appliance actually receives: the efficiency, the initial resistance and the dust-holding capacity that the end user experiences over the filter's life.
Three factors decide the finished filter's behaviour, and they interact.
Media choice sets the ceiling. PP meltblown gives a practical balance for everyday air purification. PP+PET composite adds moisture resistance for humidifying purifiers, dehumidifiers and other damp-duty appliances. PTFE membrane offers a different resistance and efficiency profile for demanding targets. The grade selected sets the filtration class, from E11 to H14/U15.
Pleating and forming turn media into a low-resistance panel. The MAX flat design is optimised for fluid dynamics: low initial resistance with large dust-holding capacity, which extends the consumable's service life and frees core design space inside the appliance.
Framing and sealing keep performance honest. A well-formed panel with clean seals prevents bypass and holds its shape through installation and use. Because Oltaven builds the whole filter, these steps are controlled together rather than sourced separately.
The result is a filter whose efficiency, resistance and capacity are set by the combination, not by any single material. Two filters of the same size can differ in resistance because their pleat geometry, media grade and sealing differ.
The ultra-flat MAX structure suits appliances where internal space is tight and airflow must stay easy. For OEM projects, the panel can be shaped to the appliance's own design drawing, including length, width, thickness and encapsulation process.

Oltaven works as an OEM/ODM partner. Over more than 20 years of filter development and manufacturing, the company has built a library of more than 1,000 developed filtration solutions, which shortens the path from a new appliance design to a working filter. The plant covers 50,000 m², including six cleanrooms totalling 20,000 m². A CNAS-recognised laboratory issues test reports on filtration efficiency, dust-holding capacity and resistance. Production runs under ISO 9001, ISO 14001 and ISO 45001, with IATF 16949 automotive quality management added in 2024. Products meet REACH and RoHS requirements and compliance documents can be provided. The company is located in Zhongshan, Guangdong, China, and has exported to Europe, the United States, Japan and South Korea for more than 20 years.
Customisation covers size, structure, media grade, frame material, logo and packaging.
To receive a quote, tell us the device or vehicle model, the size or drawing, the airflow or water flow, the operating conditions and the quantity you need. Share these details through the contact page and our team will respond with a proposal for the finished filter.
Resistance depends on the media grade, how the media is pleated and how the panel is framed and sealed. A PP meltblown panel and a PTFE membrane panel of the same footprint can show different initial resistance because air passes through them differently. Oltaven controls these forming steps together so the finished filter matches the appliance's airflow design.
The finished filter can be supplied from E11 sub-high efficiency up to H14/U15 ultra-high efficiency, depending on the media grade selected. Efficiency is set by the media choice and confirmed by testing before shipment. Tell us your target grade and we will match the media to it.
Yes. Oltaven supports 100% OEM/ODM customisation of length, width, thickness and encapsulation process based on your appliance design drawing. Media grade, frame material, logo and packaging can also be specified. The ultra-flat MAX structure is intended to free space inside compact appliances.
It starts with your appliance model, a size drawing or target dimensions, airflow, operating conditions and quantity. Our engineering team reviews the media and forming options, then produces a sample for fit and performance evaluation. After sample confirmation, production is scheduled on automated lines with IQC, IPQC and OQC controls.
For this product, standard items typically start at 500–1,000 pieces, while customised items generally start at 1,000–3,000 pieces depending on size and structure complexity. Standard lead time is 15–20 days, and customised orders ship 25–35 days after sample confirmation. Sampling usually takes 5–10 working days, with free samples available (freight collect).
In a typical household environment (annual average PM2.5 of 35 μg/m³, 8 hours of daily operation), replacement is suggested every 6–12 months. In industrial or commercial settings, 3–6 months is suggested. Oltaven can provide dust-holding test data and life curves to help you set a pressure-drop alarm threshold or replacement indicator in the appliance.
Our CNAS-recognised laboratory can test filtration efficiency, resistance and dust-holding capacity and issue reports. Production runs under ISO 9001, ISO 14001 and ISO 45001, with IATF 16949 added in 2024. Products meet REACH and RoHS requirements, and compliance documents can be supplied for customs clearance and brand support.
