This is a coffee machine water filter cartridge compatible with KitchenAid KCM5WFP, designed to reduce chlorine, odours, sediment and scale-forming minerals from tap water before they reach your brew. It combines a coconut-shell activated carbon block with food-grade ion-exchange resin to protect flavour and extend the life of automatic, semi-automatic and commercial espresso machines. The cartridge is made by Ranveth, a filter manufacturer based in Zhongshan, Guangdong, China, and is available for OEM and ODM supply.
The performance of this cartridge comes from how its two media are paired. Coconut-shell activated carbon is chosen for its high adsorption capacity and low fines, targeting residual chlorine, volatile organic compounds (VOCs) and the earthy, chemical notes that mask coffee aroma. Food-grade ion-exchange resin works on a different mechanism: it exchanges calcium and magnesium ions for sodium or hydrogen, reducing the precursors that form limescale on heating elements and brew heads. When these media are layered in the correct order and density, the carbon does the taste work while the resin does the hardness work, and neither is exhausted prematurely by the other's job.
That pairing also shapes airflow resistance and service life. A densely packed carbon block gives good contact time and contaminant removal but raises pressure drop; the resin layer is engineered to sit within a pressure range of 20–120 psi so that flow remains stable across the cartridge's life. Because the resin captures hardness rather than trapping it as loose sediment, the cartridge does not choke as quickly as a simple sediment filter would. The result is a filter that maintains flow and flavour protection for approximately 250 litres or 2–3 months, depending on local water quality and usage frequency. For buyers, this means the media combination is not a list of ingredients but a matched system: each layer supports the other's efficiency and the cartridge's usable life.

This cartridge is used wherever coffee quality depends on water quality. In automatic coffee machines, it protects boilers and flow meters from scale while keeping the brew free of chlorine taste. In semi-automatic and professional espresso machines, it supports consistent extraction by stabilising water hardness, which matters for both taste and machine maintenance intervals. Commercial coffee services use it as a softening stage before the espresso machine, particularly in areas with hard water. Beyond the KitchenAid KCM5WFP-compatible format, Ranveth supplies this media pairing in OEM water filter cartridges for coffee machine brands and aftermarket programmes. The cartridge is intended for cold water filtration only, at temperatures from 2°C to 38°C, and is not suitable for hot-water lines or machines without a cold-water inlet.

With these details, our engineers can recommend the carbon grade, resin type and layer build that balance efficiency, pressure drop and service life for your market.
Ranveth is a filter manufacturer with more than 20 years of experience in filtration research and manufacturing, exporting to Europe, the United States, Japan and South Korea for over two decades. The company operates a 50,000 m² production site in Zhongshan, Guangdong, China, including six cleanrooms totalling 20,000 m², where filter cartridges are assembled and packaged. For buyers, the most relevant capability is our in-house CNAS-accredited laboratory: it can issue test reports on filtration efficiency, contaminant holding capacity and resistance, so the media pairing in this cartridge is backed by measured data rather than assumption. Our quality systems include IATF 16949 (achieved in 2024), ISO 9001, ISO 14001 and ISO 45001, with IQC, IPQC and OQC controls across production. We also support OEM/ODM customisation of dimensions, structure, media grade, housing material, logo and packaging, and have developed more than 1,000 filtration solutions. Multiple automated production lines support monthly capacity in the millions of pieces.
To evaluate this cartridge for your coffee machine line or private-label programme, send us your device model, required size or drawing, flow or pressure requirements, operating conditions and target quantity. We will respond with a specification proposal, sample availability and a quotation. For samples and pricing, please contact our team.
It pairs premium coconut-shell activated carbon with food-grade ion-exchange resin. The carbon targets chlorine, odours and volatile organic compounds, while the resin reduces calcium and magnesium ions that form scale. This layered pairing is what drives the cartridge's efficiency, pressure drop and service life.
The cartridge is designed to reduce chlorine, odours, VOCs and scale-forming minerals, and its performance is verified by our CNAS-accredited laboratory, which can issue reports on filtration efficiency, capacity and resistance. For project-specific efficiency targets, we can test against your water conditions and share the data before you commit to a production order.
Yes. We offer OEM and ODM customisation of dimensions, connection type, media grade, housing material, logo and packaging. Send us the machine model or a sample of the original cartridge, and our engineers will propose a compatible build that matches flow and fit requirements.
Contact us with your device model, required size or drawing, flow or pressure requirement, operating conditions and estimated quantity. We will confirm sample availability and provide a quotation based on your specification. For serious B2B evaluations, samples can be arranged quickly.
The MOQ and lead time for this cartridge are confirmed per project after we review your specification, quantity and customisation needs. As a manufacturer with multiple automated lines and monthly capacity in the millions of pieces, we can support both trial orders and long-term supply programmes.
Replace it at approximately 250 litres or every 2–3 months, whichever comes first, depending on local water quality and usage frequency. In hard-water areas, the resin may exhaust faster, so monitoring taste and flow is a practical guide.
It operates at 20–120 psi (about 1.4–8.3 bar) and 2°C–38°C, and is for cold water filtration only. Do not install it on hot-water lines or outside these limits, as that can affect media performance and cartridge integrity.
Yes. We provide full OEM/ODM service, including custom logo printing, retail packaging and multi-language instructions. Our quality systems include IATF 16949, ISO 9001, ISO 14001 and ISO 45001, and we can supply compliance documentation for REACH and RoHS.
