This is a flat panel HEPA activated carbon composite filter from Oltaven that combines particle removal and odour control in one low-profile unit. It captures fine dust, pollen and other airborne particles through a HEPA layer while a carbon layer adsorbs formaldehyde, TVOC and everyday smells. It is designed for air purifiers, humidifier-purifier combos, dehumidifiers and similar appliances where space is tight. Oltaven supplies the finished filter, engineered around your device and your airflow.
Media is only the starting point. The same HEPA or carbon material can behave very differently once it is pleated, framed and sealed. Oltaven sells finished filters, not just rolls of media, because the forming steps decide what the user actually experiences: how much resistance the fan sees, how evenly air passes through, and how much dust the filter holds before it needs changing.
In a flat panel design, the media is laid out to keep the profile thin. That frees space inside the appliance for other components and helps keep resistance low. How the media is supported, cut and bonded to the frame determines whether air takes the intended path or slips around the edges. Oltaven treats framing and sealing as part of filtration performance, not as packaging.
Three factors drive the finished result: the media choice, the pleating or flat layout, and the frame and seal. For particle removal, Oltaven offers PP (polypropylene), PP+PET composite and PTFE media. Each has its own balance of efficiency, airflow resistance and dust-holding capacity. The right choice depends on the appliance’s fan curve and the target CADR, not on a single headline number.
For odour control, the carbon layer uses quality honeycomb activated carbon or modified formaldehyde-removal carbon granules. Carbon works by adsorption, so the amount and type of carbon, and how it is presented to the airflow, affect how long the filter keeps working. A flat panel format can use a thin carbon layer, but the available contact time and the total carbon mass still set the limits.
Pleating and forming change the geometry. More pleats can add surface area for dust holding, but they also raise resistance if the media is tightly packed. A flat layout favours low resistance and a slim profile. Oltaven selects the forming approach to match the device, then confirms the result on test benches. The frame and edge seal keep air from bypassing the media; without them, efficiency measured on the material would not translate to the finished filter.
The appliance’s fan is part of the system. A filter that is efficient but too restrictive can reduce total air delivery and lower the real-world clean air output. Oltaven therefore treats efficiency and resistance as a pair, and sizes the filter around the fan parameters the customer provides.
The flat, space-saving format suits products where every millimetre of internal volume matters. Because the filter handles both particles and odours, it can replace two separate filter stages in some designs, simplifying the appliance’s internal layout and the user’s replacement routine.

Oltaven’s OEM/ODM capability is central to how these filters are made. We have developed more than 1,000 filtration solutions, so a new flat panel project can often start from an existing media and forming approach rather than from zero.
The production base covers 50,000 m², including six cleanrooms with a combined area of 20,000 m². A CNAS-accredited laboratory allows us to test filtration efficiency, dust-holding capacity and resistance, and to issue reports from our own facility.
We hold IATF 16949, the automotive quality management system certification obtained in 2024, along with ISO 9001, ISO 14001 and ISO 45001. Our products meet REACH and RoHS requirements, and compliance documents can be provided for market access. With more than 20 years of filtration R&D and manufacturing experience, we have exported continuously to Europe, the United States, Japan and South Korea for over two decades.
To quote accurately, please tell us your device or vehicle model, the required size or a drawing, the airflow or water flow, the operating conditions, and the quantity you expect. If you are still at the design stage, share the fan parameters and available space, and we can recommend a media and forming combination. Contact Oltaven to begin.
Resistance depends on the media type, how tightly it is pleated or laid out, and how well the frame seals the edges. A filter with more pleats may hold more dust but can resist airflow more. Oltaven balances media and forming against your fan parameters so the finished filter works with the appliance, not against it.
It starts with your device model, cavity dimensions or drawing, target airflow or CADR, and operating conditions. Oltaven then proposes media, carbon type, flat panel layout and frame options, and produces samples for your fit and performance checks. After approval, specifications and packaging are locked for production.
Yes. Oltaven supports 100% OEM flexible customisation. We can make any length, width, thickness and frame sealing to match your housing requirements, using PP, PP+PET or PTFE media and honeycomb or modified carbon.
MOQ and lead time are set per project and confirmed in the quotation. Because every flat panel filter is built to your dimensions and media choice, Oltaven agrees these details with you before production. Please include your expected quantity in your inquiry so we can respond precisely.
Replacement depends on the media, carbon load and the appliance’s operating conditions. Oltaven tests odour-removal decay and resistance in our CNAS-accredited laboratory, and we can discuss expected service life for your specific design. The appliance’s own filter-change indicator or schedule should guide the user.
Yes. Samples are produced after the initial technical review so you can check fit and performance. Sample timing and any sample cost are confirmed in the quotation. This step helps both teams validate the media and forming choice before tooling or volume production.
Oltaven holds ISO 9001, ISO 14001, ISO 45001 and IATF 16949 certification, and our products meet REACH and RoHS requirements. Compliance documents can be provided. Our CNAS-accredited laboratory tests efficiency, dust-holding capacity and resistance, and reports are issued from our own facility.
Production follows IQC, IPQC and OQC controls, and automated lines support consistent output at high monthly volumes. The CNAS-accredited laboratory checks resistance, efficiency and odour-removal decay indicators.
