This coffee machine filter cartridge is a water purification filter compatible with CAPRESSO machines, designed to reduce sediment, rust, chlorine, odours and scale from cold water before it reaches the brew path. It combines high-quality coconut shell activated carbon with food-grade ion exchange resin and is intended for automatic, semi-automatic and commercial coffee machines, as well as OEM water filter customisation. The product is manufactured by Zanxis under ISO 9001/14001 and IATF 16949 systems, with CNAS-accredited laboratory verification.

Before specifying this cartridge, a QA or procurement engineer should confirm the values that directly affect fit and performance. The first is the interface and dimensional compatibility with the target CAPRESSO model: the cartridge is designed to the original specification for size, connection and flow parameters, but the exact machine variant should be checked. The second is the operating pressure range of 20–120 psi (1.4–8.3 bar) and the cold-water temperature limit of 2°C–38°C; installations outside these conditions may change flow behaviour and service life. The third is the expected filter life of approximately 250 litres or 2–3 months, which depends on local water hardness and daily brew volume. Finally, confirm the required filtration claims — sediment and rust interception, chlorine and odour reduction, and scale control — against the water analysis for the site. These parameters form the basis for sample validation and incoming inspection.
Zanxis recommends a structured sample sign-off before mass production. The workflow below is typical for OEM and replacement cartridge projects:
This sequence keeps the approved sample and the corresponding test data as the single technical reference for the order.
The cartridge is built around a coconut shell activated carbon block or granular bed combined with food-grade ion exchange resin. The carbon stage addresses chlorine, odours and organic compounds that affect coffee taste, while the ion exchange resin reduces hardness minerals that form scale in the boiler and brew circuit. Fine microporous interception retains sediment and rust particles that can pass through the machine's inlet. The cartridge is intended for cold water only; it should not be exposed to temperatures above 38°C. It is designed as a direct replacement for compatible CAPRESSO machines, and the same platform supports OEM customisation of dimensions, connection type, media grade and branding. Typical applications include automatic coffee machines, semi-automatic espresso machines and commercial coffee machine water softening, as well as private-label water filter cartridges for appliance brands and distributors.
Zanxis operates a self-built laboratory accredited by CNAS (China National Accreditation Service for Conformity Assessment), which can issue test reports for filtration efficiency, dust holding capacity and resistance. Production follows IQC, IPQC and OQC controls: incoming material inspection, in-process inspection and outgoing quality inspection. The manufacturing site covers 50,000 m², including six clean workshops totalling 20,000 m². The company holds ISO 9001, ISO 14001 and ISO 45001 system certifications, and obtained IATF 16949 automotive quality management system certification in 2024. Products comply with REACH and RoHS environmental regulations, and compliance documents can be provided. With more than 20 years of filtration product development and manufacturing experience, Zanxis has supplied export markets in Europe, the United States, Japan and South Korea for over 20 years, and supports OEM/ODM projects with more than 1,000 filtration solutions developed to date. Multiple automated production lines support monthly capacity of several million pieces. The company is located in Zhongshan, Guangdong, China.
To receive a sample and the relevant test report, please send the following information: the coffee machine model or vehicle model (where applicable), the required size or a drawing, the airflow or water flow requirement, the operating conditions (pressure, temperature, water hardness), and the estimated quantity. Our team will confirm the reference specification and the sample lead time. Contact us to start the verification process.
Yes. Zanxis can provide CNAS-accredited laboratory reports covering filtration efficiency, dust holding capacity and resistance for the relevant media batch. These reports are issued by our self-built laboratory accredited by CNAS. For specific projects, we can also discuss additional testing against agreed methods.
Sample validation typically takes 2–3 weeks for the sample preparation and initial performance check, depending on the customisation level. The full workflow includes fit test, performance check and report review. We recommend agreeing on the test method and acceptance criteria before sampling to avoid repeated rounds.
The cartridge uses coconut shell activated carbon and food-grade ion exchange resin to reduce chlorine, odours and hardness, and fine microporous interception retains sediment and rust. Efficiency values are available in the CNAS laboratory report for the specific media batch. Please share your target water parameters so we can match the appropriate grade.
Yes. Zanxis supports OEM/ODM customisation of dimensions, connection type, media grade, branding and packaging. We have developed more than 1,000 filtration solutions and can adapt the cartridge to your machine interface. Provide a sample or drawing and we will evaluate feasibility.
MOQ and lead time depend on the configuration and are confirmed per project. For this coffee machine filter cartridge, please state your estimated quantity and required delivery schedule. We will provide a specific quotation and production timeline after reviewing your requirements.
The nominal filter life is approximately 250 litres or 2–3 months, depending on local water quality and usage frequency. In hard water areas or high-volume commercial use, replacement may be needed sooner. We recommend monitoring flow rate and taste as practical indicators.
Yes, pre-production samples are available for fit and performance verification. We recommend the sample verification workflow: submit machine and water data, receive a sample, perform fit and performance checks, and review the test report. Sample quantities and costs are confirmed per project.
Zanxis products comply with REACH and RoHS environmental regulations, and compliance documents can be provided. The company holds ISO 9001, ISO 14001, ISO 45001 and IATF 16949 certifications. For market-specific requirements, please contact us to discuss the documentation package.
