The Thesvin coffee machine filter cartridge is a drop-in replacement for the KitchenAid KCM22WF water filter, designed to reduce scale, sediment and chlorine taste from the water feeding your brewer. It combines coconut-shell activated carbon with food-grade ion-exchange resin to protect the machine and improve coffee flavour. This cartridge is aimed at owners of KitchenAid KCM22WF coffee machines, as well as OEM and ODM buyers who need a reliable compatible filter for their own brand.
Fitment is the first thing to check. The Thesvin cartridge is built to the same key dimensions and connection geometry as the original KitchenAid KCM22WF filter, so it seats into the machine’s filter holder without modification. The housing locates positively in the holder and the water inlet and outlet align with the corresponding ports, allowing the cartridge to seal and flow as intended. Each production batch is assembly-tested and flow-tested before packing to confirm that the cartridge inserts smoothly and maintains the expected flow rate.
Because the interface is matched to the host machine, you do not need adapters or tools to install it. The cartridge simply replaces the old filter in the same position. If you are developing a new coffee machine or a private-label filter, Thesvin can adjust the housing, inlet/outlet arrangement and overall dimensions to suit your drawing; the standard compatible version is already dimensioned for the KitchenAid KCM22WF.
Inside the cartridge, coconut-shell activated carbon adsorbs chlorine, odours and organic compounds that can flatten coffee aroma, while the ion-exchange resin reduces hardness minerals that cause limescale. The fine porous structure also traps sediment, rust and other large particles before they reach the brew path. The result is cleaner water for brewing, with the minerals that contribute to good extraction largely retained.
The cartridge is intended for cold-water filtration only. It operates at pressures from 20 to 120 psi (approximately 1.4 to 8.3 bar) and at temperatures between 2 °C and 38 °C. Typical applications include automatic coffee machines, semi-automatic espresso machines and commercial coffee machines where scale control matters, as well as OEM water-filter programmes.

Thesvin operates a 50,000 m² manufacturing site in Zhongshan, Guangdong, China, including six cleanrooms totalling 20,000 m². Our quality system is certified to ISO 9001, ISO 14001 and ISO 45001, and we added IATF 16949 certification in 2024. We control dimensional consistency through incoming inspection (IQC), in-process inspection (IPQC) and outgoing inspection (OQC) for every production batch.
Our in-house laboratory is CNAS-accredited and can issue test reports for filtration efficiency, flow rate and pressure resistance. Products comply with REACH and RoHS requirements, and compliance documents are available on request. With more than 20 years of filtration manufacturing experience and exports to Europe, the US, Japan and Korea, we support OEM and ODM projects with customised dimensions, structures, media grades, logos and packaging.
To get an accurate quote, please send us the device or vehicle model, a dimensioned drawing or the old filter, the required airflow or water flow, your operating conditions, and the quantity you plan to order. Our engineering team will review fitment and respond with a specification and price. Contact us to start your inquiry.
Yes. The Thesvin cartridge is designed to the same key dimensions and connection geometry as the original KitchenAid KCM22WF filter, so it installs in the same position without adapters. Each batch is assembly-tested and flow-tested before packing to confirm fit and flow. If you have a different model, send us the model number and we will check compatibility.
Yes. A used filter is often the fastest way for us to confirm interface dimensions. Send the old part or clear photos with a ruler for scale, and our engineers will match the housing, ports and overall size. For new OEM designs, a dimensioned drawing is preferred.
The cartridge uses coconut-shell activated carbon and food-grade ion-exchange resin to reduce chlorine, odours, sediment and hardness minerals. Rated life is approximately 250 litres or 2–3 months, whichever comes first, depending on local water quality and usage. Performance testing is carried out in our CNAS-accredited laboratory.
Yes. We support OEM and ODM customisation of housing dimensions, port arrangement, filter media grade, logo and packaging. Provide your drawing or sample and target performance, and we will propose a specification. Tooling and sample development typically take 2–3 weeks.
The standard compatible model has an MOQ of 5,000 pieces, with stock or small-batch orders usually delivered in 15–20 days. OEM customised versions are recommended from 10,000 pieces, with mass production around 25–30 days after drawing and packaging approval. Lead times are confirmed with each quotation.
Yes. Standard samples can be provided free of charge, with freight paid by the customer. Custom samples may incur a small development fee, which is refundable against a bulk order. Samples are usually dispatched within 3–7 working days.
Replace the cartridge every 2–3 months or after approximately 250 litres of filtered water, whichever comes first. In areas with harder water or heavy machine use, earlier replacement helps maintain flow and scale protection. A drop in flow rate is a practical sign that replacement is due.
The cartridge is for cold-water filtration only, with an operating pressure of 20–120 psi (about 1.4–8.3 bar) and a water temperature of 2 °C to 38 °C. It is not suitable for hot water or steam lines. If your machine operates outside these ranges, contact us to discuss alternatives.
