This coffee machine filter cartridge is a direct replacement for the KitchenAid KCM22WF water filter, using coconut-shell activated carbon and food-grade ion exchange resin to reduce sediment, rust, chlorine and scale-forming minerals from the water feeding your coffee machine. It is designed for owners and operators of automatic, semi-automatic and commercial coffee machines who want consistent water quality and longer equipment life. The cartridge is manufactured by Jyntrel, a filter specialist based in Zhongshan, Guangdong, China, with more than 20 years of export experience.
In a coffee machine, water rather than air is the working fluid, and the filter sits on the cold-water inlet line before the pump and boiler. The cartridge operates at pressures from 20 to 120 psi (approximately 1.4 to 8.3 bar) and at water temperatures between 2°C and 38°C; only cold-water filtration is supported. These conditions match typical municipal supply pressures and the inlet temperatures found in domestic and commercial coffee equipment.
The flow path runs from the water source through the cartridge, where the coconut-shell activated carbon adsorbs chlorine, odours and organic compounds, while the ion exchange resin reduces hardness minerals that cause scale. The filtered water then continues to the pump and brewing circuit. Because the cartridge is installed upstream of the boiler, it helps protect heating elements and valves from scale build-up, which is a common cause of reduced flow and downtime in coffee machines.
Flow rate and pressure drop depend on the machine's pump and the local water conditions. For selection, Jyntrel asks for the inlet pressure, water temperature and the typical daily volume so that the cartridge can be matched to the duty cycle. The filter life is approximately 250 litres or 2–3 months, whichever comes first, and this will vary with local water quality and usage frequency.
The filtration media combine high-quality coconut-shell activated carbon with food-grade ion exchange resin. This combination targets the main water issues that affect coffee taste and machine reliability: chlorine and chloramines that dull flavour, sediments that clog small orifices, and hardness minerals that form scale. The cartridge provides fine microporous interception to capture sand, rust and other large particles, protecting downstream components.
By reducing scale and sediment, the cartridge helps maintain stable flow and temperature in the brewing system, supporting consistent extraction and flavour. It is not intended to soften water to zero hardness or to remove all minerals; the goal is to balance water chemistry for coffee while protecting the equipment. For applications requiring specific water chemistry, Jyntrel can discuss alternative media blends during the selection process.
To recommend the right cartridge or to develop a custom solution, Jyntrel needs a clear picture of your system and operating conditions. Please provide the following information:
With these details, Jyntrel can confirm compatibility, estimate filter life and propose a cartridge configuration. For OEM projects, the team can customise media formulation, dimensions, connector design, logo and packaging. Prototyping typically takes 2–3 weeks, depending on complexity.

The cartridge is used in household automatic coffee machines, semi-automatic espresso machines and commercial coffee equipment where water quality affects both taste and reliability. It is also suitable for office coffee systems, cafés and other food-service settings that require consistent water for brewing. In commercial environments, the cartridge can be part of a water treatment plan to reduce scale in steam wands, boilers and valves.
Beyond coffee, the same platform can be adapted for other low-flow water filtration applications that need chlorine reduction and scale control. Jyntrel works with equipment manufacturers and distributors to tailor the cartridge to specific machine models and market requirements.
Jyntrel operates a 50,000 m² production facility in Zhongshan, Guangdong, China, including six cleanrooms totalling 20,000 m². Multiple automated production lines support a monthly capacity of millions of pieces, providing supply stability for large OEM programmes. The company has been exporting filtration products to Europe, the United States, Japan and South Korea for more than 20 years.
Quality control follows IQC, IPQC and OQC processes from incoming materials to final inspection. The in-house laboratory is CNAS-accredited and can perform filtration efficiency, flow rate, pressure resistance and extractables testing. Jyntrel is certified to ISO 9001, ISO 14001 and ISO 45001, and achieved IATF 16949 certification in 2024. Products comply with REACH and RoHS requirements, and compliance documentation can be provided. For OEM/ODM projects, Jyntrel has developed more than 1,000 filtration solutions and offers customisation of dimensions, structure, media grade, logo and packaging.
To receive a tailored recommendation or a quotation, please share your coffee machine model, required size or drawing, inlet pressure and temperature, daily water consumption, and estimated order quantity. If you are considering OEM customisation, let us know your target specifications and packaging requirements. Our team will respond with a proposal that fits your system and market needs.

This filter is designed for water filtration in coffee machines, not for air or high-velocity airflow. It operates at water pressures of 20–120 psi and temperatures of 2°C–38°C. For air filtration applications, please contact Jyntrel to discuss a suitable product.
For this water filter, we need the inlet water pressure (psi or bar), water temperature, and typical daily water consumption (litres per day) rather than airflow data. Please also provide the coffee machine model and any space constraints. With these details, we can confirm compatibility and estimate filter life.
Yes, the cartridge is rated for operating pressures from 20 to 120 psi (approximately 1.4 to 8.3 bar). If your system pressure exceeds 120 psi, a pressure regulator should be installed upstream. Please confirm your actual inlet pressure when requesting a quote.
Yes, Jyntrel offers OEM/ODM customisation including dimensions, connection type, media formulation, logo and packaging. We can adapt the cartridge to fit other coffee machine models or specific water conditions. Prototyping typically takes 2–3 weeks, depending on complexity.
The MOQ for standard compatible cartridges is 5,000 pieces, with a lead time of 15–20 days for stock or small batch orders. For OEM customised versions, the MOQ is typically 10,000 pieces, and production including tooling and packaging development takes about 25–30 days.
The filter life is approximately 250 litres or 2–3 months, whichever comes first, depending on local water quality and usage frequency. In areas with harder water or higher consumption, more frequent replacement may be needed. We recommend monitoring flow and taste to determine the optimal replacement interval.
Yes, standard samples can be provided free of charge (freight collect), and custom samples may incur a small development fee that is refundable upon order confirmation. Samples are usually dispatched within 3–7 working days. Please share your machine model and operating conditions so we can send the most suitable sample.
