This is a Thesvin coffee machine water filter cartridge compatible with MR.COFFEE machines. It filters chlorine, odours, hardness minerals and heavy metals from tap water before they reach your brew. It is designed for owners of automatic and semi-automatic espresso machines, drip coffee makers, high-end water dispensers, ice makers and sports filter bottles who want consistent taste and less scale. Thesvin manufactures it as a direct replacement, with full OEM customisation available.
Fitment comes first. The cartridge is built to the original MR.COFFEE specification so that its outside dimensions, inlet and outlet ports and locking features match the host machine. That means you install it the same way as the part you remove: seat the cartridge into its housing, twist or click it into place if your machine uses a bayonet fitting, and run water through to flush the cartridge before brewing.
Because the housing shape and connector style are controlled by the machine, Thesvin does not publish a universal drawing. Instead, we match the part to your existing cartridge or to the drawing you supply. If your machine uses a push-in connector, a threaded collar or a proprietary clip, tell us which and we will confirm the interface before quoting. For OEM projects, the outer shell can be tooled to your machine's interface, and the internal filter media ratio can be adjusted to suit your water conditions and flow target.
The cartridge uses a three-stage filtration path. Water first passes through a high-density microporous fibre layer that traps sediment and particulate matter. It then moves through high-iodine-value coconut shell activated carbon, which adsorbs residual chlorine, off-tastes and odours. The final stage is food-grade ion exchange resin, which softens the water by reducing calcium and magnesium hardness and helps prevent scale build-up on the boiler and heating elements. The combination also helps reduce lead, mercury and other harmful heavy metal ions.
The result is water that supports the flavour of the coffee rather than masking it. Chlorine and odour removal is the main reason coffee tastes flat when brewed with untreated tap water; scale prevention is the main reason machines lose temperature stability and flow over time. Thesvin does not claim that this cartridge makes water potable where the supply is unsafe. It is a taste, odour and scale-control filter for machines connected to a drinking water supply.

| Quality certification | Thesvin's 50,000 m² plant is certified to ISO 9001 and IATF 16949. Filter materials meet demanding drinking water safety standards and are checked by a CNAS-accredited laboratory |
Thesvin runs dimensional and performance checks at three points: incoming material inspection (IQC), in-process inspection (IPQC) and outgoing inspection (OQC). Each batch is checked for fit-critical dimensions, media weight and flow, and retained samples are kept for traceability. The company's IATF 16949 certification, obtained in 2024, supports a documented approach to dimensional consistency across production runs, which matters when a cartridge has to click into a machine housing the same way every time.
Thesvin's in-house laboratory is CNAS-accredited and can issue test reports covering filtration efficiency, contaminant capacity and resistance. The 50,000 m² facility includes six clean workshops totalling 20,000 m², and the plant holds ISO 9001, ISO 14001 and ISO 45001 certification. Products meet REACH and RoHS requirements and compliance documents can be supplied. With more than 20 years of filtration manufacturing and export experience to Europe, the United States, Japan and Korea, Thesvin has developed over 1,000 filtration solutions and runs multiple automated production lines with monthly capacity in the millions of pieces.
To get a quote, send us the device or vehicle model (for this product, the coffee machine or water dispenser model), the cartridge size or a drawing, the airflow or water flow your system expects, the operating conditions (water hardness, chlorine level, temperature, pressure) and the quantity you need. If you do not have a drawing, a photo and a few dimensions of the old part are enough to start. Contact our team with these details and we will confirm fitment, sample availability and lead time for your project.
The cartridge is produced to the original MR.COFFEE specification, so its dimensions, connector and flow characteristics are compatible with the original part and it can be used as a direct replacement. Send us your machine model or a photo of the old cartridge and we will confirm the match before you order.
Yes. A photo of the old cartridge with a few key dimensions is usually enough for us to identify the interface and check it against our existing tooling. For custom OEM projects we can also work from a physical sample.
It uses a three-stage path: a fibre layer for sediment, coconut shell activated carbon for chlorine and odour removal, and ion exchange resin for hardness reduction and scale prevention. The same media set also helps reduce lead, mercury and other harmful heavy metal ions.
The standard replacement interval is 2 months or 60 gallons (about 227 litres) of filtered water, whichever comes first. Actual life depends on your local water quality; for OEM projects the media ratio can be adjusted to suit the market you sell into.
Yes. Thesvin supports full OEM and ODM work: housing shape, connector and clip style, media ratio, colour and packaging can all be customised. Development of a new fitment typically takes 15–30 days, and we can work from your sample or drawing.
Standard models usually have an MOQ of 1,000–2,000 pieces; custom projects are negotiated based on specification and packaging. We can provide 1–3 free samples of stock models for testing, with the customer covering international courier costs, and custom sample fees are credited against the bulk order.
Standard orders typically ship in 25–35 days and custom orders in 35–45 days, depending on quantity and specification. Thesvin has exported to Europe, the United States, Japan and Korea for more than 20 years and can handle FOB, CIF and DDP terms.
We control dimensional consistency through IQC, IPQC and OQC checks, automated media filling, and retained samples kept for traceability. The plant's IATF 16949 certification, obtained in 2024, supports a documented quality process across production runs. Contact us with your requirements to start an inquiry.
