This Oltaven coffee machine filter is a water-purifying cartridge compatible with Cuisinart coffee machines. It reduces chlorine, odours, heavy metals and scale-forming minerals using a coconut-shell activated carbon and food-grade ion exchange resin core. It is designed for coffee machine owners, service providers and brands seeking a reliable replacement filter or a custom OEM/ODM solution.
The performance of a water filter is not set by the filter media alone. The way the media is pleated, framed and sealed determines how water flows through it, how much contact time it gets, and how long the filter lasts. At Oltaven, we sell finished filters, not just media. Our engineers combine high-quality coconut-shell activated carbon with food-grade ion exchange resin, then form the filter element to balance flow, resistance and capacity. The result is a cartridge that fits your machine, protects it from scale and delivers consistent water quality for better-tasting coffee.
Several design choices influence how a finished coffee machine filter performs. The selection of coconut-shell activated carbon affects chlorine reduction and taste improvement, while the ion exchange resin targets hardness minerals that cause scale. The forming process — how the media is pleated and packed into the housing — controls the contact time and pressure drop. A tighter pack increases contact but can raise resistance; a looser pack reduces resistance but may shorten filter life. Sealing is equally important: a proper seal prevents bypass, ensuring all water passes through the media. Oltaven's production takes place in cleanrooms with automated lines, and each batch is tested for flow, pressure drop and seal integrity in our CNAS-accredited laboratory. This is why two filters of the same size can behave differently — the difference lies in media choice, forming and sealing.
This filter is suitable for automatic coffee machines, semi-automatic espresso machines and commercial coffee machines that require softened water. It is also available for OEM water filter customisation. Whether you run a café, manage a hotel or need replacement filters for a coffee machine brand, this filter helps reduce scale, extend equipment life and maintain consistent coffee flavour.

Oltaven has over 20 years of experience in filtration product development and manufacturing, exporting to Europe, the US, Japan and South Korea. Our OEM/ODM capability is backed by more than 1,000 developed filtration solutions. The 50,000 m² production facility includes six cleanrooms totalling 20,000 m², where coffee machine filters are assembled and sealed in a controlled environment. Our in-house laboratory is CNAS-accredited and can issue test reports for filtration efficiency, dust holding capacity and resistance. We hold IATF 16949 (obtained in 2024) and ISO 9001, ISO 14001 and ISO 45001 certifications. Products comply with REACH and RoHS regulations, and compliance documents are available upon request.
To begin, please tell us your device or vehicle model (if applicable), the required size or provide a drawing, the airflow or water flow rate, operating conditions (pressure, temperature, water quality) and your estimated quantity. Our team will respond with a tailored solution. Contact Oltaven to discuss your coffee machine filter needs or any other filtration project.
Resistance depends on how the filter media is pleated and packed, and on the sealing design. A tighter pack increases contact time for better filtration but can raise resistance; a looser pack reduces resistance but may shorten filter life. Oltaven balances these factors through precise forming and sealing, and tests each batch for pressure drop in our CNAS-accredited laboratory.
An OEM project starts with your inquiry. Share your device model, required size or drawing, water flow rate, operating conditions and estimated quantity. Our team will review your requirements and provide a technical proposal and quotation, followed by sampling and customisation.
This filter uses coconut-shell activated carbon and food-grade ion exchange resin to reduce chlorine, odours, heavy metals such as lead and copper, and scale-forming minerals. It also captures sediment and rust particles through fine microporous interception. Performance data is verified in our CNAS-accredited laboratory.
Yes. We offer full OEM/ODM customisation including media formulation (activated carbon, ion exchange resin, KDF combinations), housing dimensions, connection type, logo printing and packaging. With over 1,000 developed filtration solutions, we can tailor the filter to your specifications.
We provide 1–3 standard samples free of charge; you only cover the international shipping cost. Custom samples are available for a fee, which is deductible from your formal order. Samples are typically shipped within 3–5 working days. To receive a quote, please contact us with your specifications.
The MOQ for standard compatible models is 5,000 pieces, with a lead time of 15–20 days for stock or small batch orders. For OEM customised models, we recommend an MOQ of 10,000 pieces, with a production lead time of about 25–30 days including tooling and packaging development.
The filter life is approximately 250 litres or 2–3 months, depending on local water quality and usage frequency. Replace the filter when you notice a change in water taste, reduced flow, or after the recommended interval to maintain coffee quality and protect your machine.
Oltaven holds ISO 9001, ISO 14001 and ISO 45001 certifications, and obtained IATF 16949 in 2024. Our production follows medical supplies GMP standards, and our in-house CNAS-accredited laboratory verifies filtration performance. Products comply with REACH and RoHS regulations.
