The Thesvin coffee machine filter cartridge is a drop-in water filter designed for KRUPS coffee machines. It uses a blend of coconut-shell activated carbon and food-grade ion-exchange resin to reduce chlorine, heavy metals, limescale, and organic impurities from the water before it reaches your brew path. It is intended for automatic, semi-automatic, and commercial coffee machines, as well as OEM water-filter programs. Thesvin manufactures this cartridge with fitment-first engineering, so the outer dimensions and connection interface match the host machine’s filter seat.
Fitment is the first variable we control. The cartridge is dimensioned to seat into the filter holder of KRUPS machines that accept a cartridge-style filter. The housing locates positively in the seat, and the water path seals at the inlet and outlet so that unfiltered water does not bypass the media. Because the interface is a direct replacement for the original cartridge, no adapter is needed and the machine’s normal filter-change routine applies.
From a structural standpoint, the cartridge body is rigid enough to resist the pressure differential across the filter without deforming, and the inlet and outlet ports are sized to match the machine’s flow path. This keeps pressure drop predictable and protects the machine’s pump and heating element from scale-related stress. If your machine uses a different seat depth or connection geometry, we can review a drawing or an old part and adjust the housing accordingly. The goal is a part that installs without forcing, seals without leaking, and can be removed at the end of its service life without tools.
The filtration media combines high-quality coconut-shell activated carbon with food-grade ion-exchange resin. The activated carbon adsorbs residual chlorine, off-flavours, and organic impurities, while the ion-exchange resin reduces hardness minerals that form limescale. The cartridge also provides fine microporous interception to capture sediment, rust, and other larger particles that can pass through the water supply. This combination improves water taste and protects the coffee machine’s internal heating components from scale build-up.
The cartridge is rated for cold-water filtration only, with an operating temperature range of 2°C to 38°C and an operating pressure of 20–120 psi (approximately 1.4–8.3 bar). It is not intended for hot-water lines or for water outside those conditions. The media is contained within the cartridge so that the filter can be changed as a single unit, and the materials that contact water are selected to meet food-contact requirements.

Thesvin operates a 50,000 m² production site in Zhongshan, Guangdong, China, including six cleanrooms with a combined area of 20,000 m². Quality control follows IQC, IPQC, and OQC stages: incoming materials are inspected, in-process checks monitor dimensional consistency, and outgoing inspections verify the finished cartridge before shipment. The company holds ISO 9001, ISO 14001, and ISO 45001 certifications and was awarded IATF 16949 certification in 2024. An in-house CNAS-accredited laboratory can issue test reports for filtration efficiency, dust holding capacity, and resistance, which supports the dimensional and performance consistency of each batch.
For standard compatible cartridges, the MOQ is 5,000 pieces, and stock or small-batch orders typically ship within 15–20 days. OEM customised versions have a suggested MOQ of 10,000 pieces, with a production cycle of about 25–30 days including tooling and packaging development. Multiple automated production lines support a monthly capacity of several million pieces. Thesvin has more than 20 years of filtration product development and manufacturing experience, with continuous exports to Europe, the United States, Japan, and South Korea. Products comply with REACH and RoHS environmental regulations, and compliance documents can be provided. Packaging can be customised for destination-market requirements, and shipping can be arranged under FOB, CIF, or DDP terms.
To move from a general enquiry to a fitment-confirmed quotation, send us the following: the coffee machine model or a photo of the filter seat; a drawing, dimensions, or the old part itself; the required water flow rate; the operating pressure and temperature at the installation point; and your target order quantity. If you are developing an OEM cartridge for a new machine, include the seat geometry and any packaging or branding requirements. Our team will review the fitment and respond with a specification and sample plan. Contact Thesvin to start the review.
The Thesvin cartridge is dimensioned for KRUPS machines that accept a cartridge-style filter in the filter seat. Fitment is confirmed by matching the seat depth, inlet and outlet positions, and overall envelope. If you send your machine model or a photo of the existing filter, we can confirm compatibility before you order.
Yes. An old cartridge is often the fastest way to start a fitment review because it shows the exact interface, seal locations, and overall dimensions. Send the used part or clear photos with a ruler for scale, and Thesvin will compare it against the standard housing or propose a tooling-adjusted version.
The cartridge combines coconut-shell activated carbon and food-grade ion-exchange resin to reduce residual chlorine, heavy metals, limescale, off-flavours, and organic impurities, and it provides fine microporous interception of sediment and rust. Thesvin’s CNAS-accredited laboratory can issue test reports for filtration efficiency and resistance on request.
The rated life is approximately 250 litres or 2–3 months, whichever comes first, depending on local water quality and usage frequency. In hard-water areas or high-volume use, replacement may be needed sooner. The cartridge is changed as a single unit.
Yes. For OEM and ODM projects, Thesvin provides samples for bench fitting and water-flow checks before mass production. Sample quantities and lead times are confirmed with the quotation, which is prepared after the fitment review.
Standard compatible cartridges have an MOQ of 5,000 pieces, with stock or small-batch orders typically shipping within 15–20 days. OEM customised versions have a suggested MOQ of 10,000 pieces and a production cycle of about 25–30 days, including tooling and packaging development.
Yes. Thesvin supports OEM/ODM customisation of dimensions, housing structure, filter media formulation, logo, and packaging. With more than 20 years of filtration development experience and over 1,000 filtration solutions developed, the team can adapt the cartridge to a specific seat geometry or water condition.
Production follows ISO 9001/14001, IATF 16949, and medical supplies GMP standards, and the company’s laboratory holds CNAS accreditation. Thesvin also holds ISO 9001, ISO 14001, and ISO 45001 certifications and can provide REACH and RoHS compliance documents. Send your required documentation list with your enquiry so we can confirm what is available.
