The Oltaven coffee machine filter cartridge is a water purification filter compatible with KitchenAid KCM22WF coffee machines. It combines coconut-shell activated carbon and food-grade ion exchange resin to reduce sediment, rust, chlorine, odours and scale-forming minerals from cold water, helping to protect the machine and keep coffee flavour consistent. It is designed for households and cafés using automatic, semi-automatic or commercial coffee machines, as well as for OEM water filter projects.
A filter is more than the sum of its media. The coconut-shell activated carbon provides a high surface area for adsorbing chlorine, organic compounds and odours, while the food-grade ion exchange resin exchanges hardness minerals such as calcium and magnesium for softer ions, reducing limescale build-up. But the finished cartridge’s behaviour depends on how those media are packed, shaped and sealed. Oltaven sells finished filters, not just media: the carbon and resin are selected, blended and then formed into a cartridge that fits the intended housing and delivers repeatable water flow.
Forming choices such as pleating, framing and sealing determine how water travels through the filter. A uniform pleat pack gives a large filtration area within a compact cartridge, which helps maintain flow and dirt-holding capacity. The frame and end caps hold the media in place and direct water through the intended path, while sealing prevents bypass that would let unfiltered water reach the outlet. These details are often invisible to the user, but they decide whether the cartridge delivers its rated life and whether it fits the machine without leaks.
Three factors dominate finished performance: media choice, forming and sealing. Media choice sets the baseline for what can be removed. Coconut-shell activated carbon is chosen for its adsorption characteristics and low impurity profile, while food-grade ion exchange resin is selected for hardness reduction without releasing undesirable substances. The ratio and packing density of the two media influence both filtration efficiency and resistance: more media can increase capacity but may raise pressure drop, so the balance is tuned for each application.
Forming turns loose media into a usable cartridge. Pleating increases surface area, which helps lower resistance for a given flow rate and extends the time before the filter clogs. Framing supports the pleats and maintains spacing so they do not collapse under pressure. Sealing closes the ends and joins the frame to the media pack, preventing water from bypassing the filtration path. A well-formed cartridge keeps its shape through pressure fluctuations and delivers consistent flow from first use to end of life.
For this coffee machine filter, the finished cartridge is specified for a working pressure of 20–120 psi (approximately 1.4–8.3 bar) and an operating temperature of 2°C–38°C, cold water only. The micron rating is described as fine microporous interception that effectively captures sediment, rust and other large particles. The effective filter life is approximately 250 litres or 2–3 months, depending on local water quality and usage frequency. These figures reflect the finished product, not the raw media alone.
This cartridge is intended for cold-water filtration in coffee machines. Typical uses include fully automatic coffee machines, semi-automatic espresso machines, and commercial coffee machines where water softening helps protect boilers and maintain taste. It is also suitable as an OEM water filter cartridge for appliance brands and distributors that need a compatible replacement for KitchenAid KCM22WF. Because the cartridge reduces hardness minerals, it can help limit scale formation in the machine’s water circuit, supporting consistent brewing temperature and flavour.

Oltaven is based in Zhongshan, Guangdong, China, and has more than 20 years of experience in filtration product development and manufacturing, with continuous exports to Europe, the United States, Japan and South Korea. Our OEM/ODM capability covers dimensions, structure, filter media grade, frame material, logo and packaging, and we have developed more than 1,000 filtration solutions.
The production site covers 50,000 m², including six cleanrooms totalling 20,000 m². Our in-house laboratory is CNAS-accredited and can issue test reports for filtration efficiency, dust holding capacity and resistance. We have been certified to IATF 16949 (obtained in 2024) and hold ISO 9001, ISO 14001 and ISO 45001 system certifications. Products comply with REACH and RoHS environmental regulations, and compliance documents are available on request. Quality control follows IQC, IPQC and OQC processes across the production flow.
To begin, please tell us your device or vehicle model, the size or a drawing, the required airflow or water flow, your operating conditions, and the quantity you plan to order. This helps us recommend the right media and forming for your finished filter. Contact Oltaven to discuss your OEM/ODM coffee machine filter cartridge project.
Resistance depends on media choice, packing density, pleat geometry and sealing quality. A pleated design with a larger surface area can lower resistance for a given flow, while denser media may increase capacity but raise pressure drop. The finished filter’s resistance is therefore a result of how the media is formed and assembled, not just the cartridge dimensions.
Coconut-shell activated carbon adsorbs chlorine, odours and organic compounds that can mask coffee flavour, while food-grade ion exchange resin reduces hardness minerals that contribute to scale and can affect extraction. Together they support cleaner-tasting water and more consistent brewing. The exact balance is tuned during forming so the finished cartridge delivers the intended filtration without excessive resistance.
An OEM project starts with your requirements: device model, dimensions or drawing, water flow, operating conditions and target quantity. We then review feasibility, propose media and forming, and produce samples for your testing. After sample approval, we proceed to mass production with IQC, IPQC and OQC quality control.
Yes. We provide samples for evaluation and a quotation based on your specifications and quantity. Please share your device model, size or drawing, flow requirement and operating conditions so we can recommend the right configuration. Contact us through the inquiry form to start.
For this coffee machine filter cartridge, the standard compatible version has an MOQ of 5,000 pieces, with lead times typically 15–20 days for stock or small batch orders. OEM customised versions are recommended at 10,000 pieces or more, with mass production lead times around 25–30 days including tooling and packaging development. Lead times are confirmed per project.
The effective filter life is approximately 250 litres or 2–3 months, whichever comes first, depending on local water quality and usage frequency. Replace the cartridge when you notice reduced flow, increased scale or taste changes, or according to your machine manufacturer’s recommendation. Regular replacement helps protect the coffee machine and maintain water quality.
Production follows ISO 9001/14001, IATF 16949 and medical supplies GMP standard, and our in-house laboratory is CNAS-accredited for tests such as filtration efficiency, dust holding capacity and resistance. Products comply with REACH and RoHS environmental regulations, and compliance documents are available. These systems support batch consistency and traceability.
Yes. Our OEM/ODM service covers dimensions, structure, filter media grade, frame material, logo and packaging. We have developed more than 1,000 filtration solutions and can adapt the cartridge for other coffee machine models based on your drawing or sample.
