This coffee machine filter cartridge is a drop-in water filter compatible with KitchenAid KCM5WFP brewers. It filters chlorine, sediment, and scale-forming minerals from tap water before they reach the brew path. It is designed for cafés, offices, and home users who want consistent coffee taste and fewer descaling cycles. Thesvin manufactures this cartridge with food-grade activated carbon and ion exchange resin.
The cartridge is shaped to sit in the water reservoir of KitchenAid KCM5WFP machines. Its outer dimensions follow the original filter's footprint, so the housing seats without forcing the lid or interfering with the water inlet. The outlet end is molded to match the reservoir's filter holder, allowing the cartridge to lock into place with a simple push. Once seated, the flow path is sealed to prevent unfiltered water from bypassing the media.
Because the housing is made from food-grade plastic, it resists swelling and cracking when exposed to cold water over the service life. The cartridge is intended for cold-water filtration only. Do not install it in hot-water lines or in machines that exceed 38°C water temperature. For OEM projects, Thesvin can adjust the connector geometry, housing length, and label placement to match a specific reservoir drawing.
The filtration media combines high-adsorption coconut-shell activated carbon with food-grade ion exchange resin. The carbon layer reduces chlorine, off-flavors, and volatile organic compounds (VOCs) that can flatten coffee aroma. The resin layer targets calcium and magnesium ions, the minerals that form scale on heating elements and brew heads. Together, these stages help maintain stable extraction and protect the machine's boiler.
A fine microporous structure also intercepts larger particles such as sediment and rust that may enter the reservoir from municipal supply. The cartridge does not remove beneficial minerals entirely; the ion exchange capacity is balanced to reduce hardness while leaving enough mineral content for good taste. This makes it suitable for automatic drip machines, semi-automatic espresso machines, and commercial coffee brewers that require softened water.

Thesvin operates a 50,000 m² manufacturing facility in Zhongshan, Guangdong, China, including six cleanrooms totaling 20,000 m². Coffee machine filter cartridges are assembled and packed in a controlled environment to avoid secondary contamination. The factory holds IATF 16949 certification (obtained in 2024) and ISO 9001, ISO 14001, and ISO 45001 system certificates. An in-house CNAS-accredited laboratory supports filtration efficiency, pressure drop, and media performance testing. Quality control follows IQC, IPQC, and OQC stages, with batch records and retention samples for traceability.
Standard compatible cartridges ship from stock or with a 15–20 day lead time for small orders. OEM customisation typically requires 25–30 days after sample approval, depending on packaging and connector changes. We export to Europe, the United States, Japan, and South Korea, and can provide REACH and RoHS compliance documents on request. Packaging can be configured for retail shelves or e-commerce fulfillment, including individual poly bags and printed boxes.
To get a precise quote, send us the device model, a dimensioned drawing or the old filter, your required water flow or pressure, operating conditions, and estimated annual quantity. Our engineers will confirm fitment and propose the right specification. Contact us to start your inquiry.
Yes. This cartridge is designed as a drop-in replacement for the KitchenAid KCM5WFP water reservoir. Its housing matches the original filter's footprint and outlet connector. For other models, send us a photo of your filter holder and we will check compatibility.
Yes. You can send a used original filter or a clear photo with a ruler for scale. Our engineering team will measure key dimensions and confirm whether the standard housing fits or a custom adjustment is needed.
The rated life is approximately 250 L or 2–3 months, whichever comes first. Actual life depends on your local water hardness and daily brew volume. In hard-water areas, replace closer to the 2-month mark.
For standard compatible cartridges, the MOQ is 5,000 pieces. For OEM customisation with your logo or packaging, the recommended MOQ is 10,000 pieces. Mixed-model orders may be discussed with our sales team.
Standard cartridges typically ship within 15–20 days. OEM orders with custom packaging or connector changes usually take 25–30 days after sample approval. We will confirm the schedule when you place your order.
Yes. We provide 2–5 free standard samples to B2B customers for fit and water testing. Samples are usually dispatched within 3–7 days; you cover the international courier cost. Custom samples may incur a fee, which is credited against mass production.
