This is a coffee machine water purifying filter cartridge compatible with BREVILLE machines, made by Oltaven. It combines coconut-shell activated carbon with food-grade ion exchange resin to reduce chlorine, odour, scale-forming calcium and magnesium, and heavy metals before the water reaches the brew path. It is built for automatic, semi-automatic and commercial espresso machines, and for businesses that want the same cartridge under their own brand through OEM/ODM supply.
Filtration media is the starting point, not the product. A finished cartridge is the result of a chain of decisions: which media grades to combine and in what ratio, how tightly the carbon is packed, how the resin bed is held in place, how the housing is formed, and how every joint is sealed. Each decision changes what the cartridge removes, how hard the machine's pump has to work, and how long the cartridge lasts. Oltaven sells the finished cartridge, so we take responsibility for that whole chain rather than for a bag of media.
The media in this cartridge work in sequence. Coconut-shell activated carbon has a fine pore structure and a high surface area, so it adsorbs chlorine and the organic compounds behind off-flavours quickly. Ion exchange resin then exchanges hardness ions for softer ones, which is what limits limescale build-up in the boiler and on the shower screen. If the carbon layer is too loose, water channels through it and chlorine passes; if it is packed too densely, resistance rises and flow drops. Forming and filling control that balance, which is why two cartridges with the same media list can behave very differently.
Three outcomes matter to a coffee machine owner: how much is removed, how much pressure the cartridge costs, and how much water it can treat. All three are set during manufacturing.
Filtration accuracy here is fine microporous interception: the cartridge blocks larger particles such as sediment and rust that would otherwise reach the machine, while the carbon and resin handle dissolved impurities. Because the cartridge is rated for cold water only, operating temperature is limited to 2°C–38°C.
The cartridge is used in automatic bean-to-cup machines, semi-automatic espresso machines and commercial coffee equipment where scale control protects the boiler. In offices, cafés and chains, changing cartridges on a schedule keeps taste consistent across machines and sites. It is also supplied as a private-label item: distributors and appliance brands order it with their own logo, packaging and documentation for their aftermarket programmes.
Because hardness varies widely between water supplies, the same cartridge can last noticeably longer in soft water than in hard water. For OEM buyers, the media ratio can be adjusted to the target market's typical water, which is one reason to discuss the destination market early in a project.

Oltaven has more than 20 years of filtration product development and manufacturing experience and has developed over 1,000 filtration solutions, which is the base we work from when a customer needs a cartridge adapted to a new machine or market. Our plant in Zhongshan, Guangdong, China covers 50,000 m², including six cleanrooms with a combined area of 20,000 m², so cartridges are produced in a controlled environment. A CNAS-accredited laboratory supports testing of filtration efficiency, dust holding capacity and resistance, and reports accompany development and quality work. Our quality systems hold ISO 9001, ISO 14001 and ISO 45001 certification, and in 2024 we obtained IATF 16949 certification. Products meet REACH and RoHS requirements, with compliance documents available. We export to Europe, the United States, Japan, South Korea and other markets, and run IQC, IPQC and OQC checks across the process.
Tell us the device model, the cartridge size or a drawing, the airflow or water flow you need, the operating conditions, and your planned quantity. Send these details through our contact page and our team will respond with a proposal for a finished cartridge that fits your machine and your market. We welcome long-term OEM and ODM partnerships.
Size sets the outside envelope, not the inside. Resistance is governed by how tightly the carbon and resin are packed, how evenly water is distributed across the bed, and how the housing and seals route the flow. A loosely filled cartridge may channel and lose efficiency, while an over-packed one raises pressure drop. Oltaven controls filling and forming so the finished cartridge stays within the stated 20–120 psi (about 1.4–8.3 bar) working range.
Coconut-shell activated carbon adsorbs chlorine and the organics behind off-flavours, while food-grade ion exchange resin exchanges hardness ions to limit scale. The ratio and bed depth determine how complete that removal is and how long it lasts. Rated life is about 250 litres or 2–3 months, depending on local water quality and use frequency.
Yes. As part of OEM/ODM work we can adjust the housing structure and dimensions to suit different machine models, tune the media formulation for the target market's water, and add your logo, retail packaging and multilingual instructions. Our engineering team can provide a custom proposal within 7 working days.
It starts with your requirements: device model, size or drawing, required water flow, operating conditions and planned quantity. We then propose media and structure, produce samples for your validation, and finalise tooling and packaging before mass production. Requests come through our contact page and are reviewed by the engineering team.
The MOQ for the standard compatible version is 5,000 pieces, with stock or small-batch orders typically delivered in 15–20 days. For OEM customised versions we recommend 10,000 pieces or more, and mass production including tooling and packaging development takes about 25–30 days.
Yes. Free samples are available for standard specifications, with the customer covering international courier costs; customised samples are quoted according to tooling and development cost and can be credited against a bulk order. Samples usually ship within 3–7 working days with performance reports from our CNAS-accredited laboratory.
Replace it at about 250 litres or every 2–3 months, whichever comes first. Hard water or heavy daily use will shorten that interval, so sites with high throughput should track litres treated rather than calendar time alone.
Products meet REACH and RoHS requirements and we can supply compliance documents, along with export paperwork such as commercial invoice, packing list and certificates of origin. If your market needs specific declarations, tell us at the inquiry stage and we will confirm what can be provided. Contact us through our contact page to start.
