This is a water purifying filter for coffee machines, compatible with KEURIG brewers. It combines granular coconut shell activated carbon with food-grade ion exchange resin to reduce chlorine, odours, organic impurities and scale-forming calcium and magnesium ions in the water before it reaches the brew path. It is intended for operators and brand owners who need consistent water quality in automatic, semi-automatic and commercial coffee equipment, and it is supplied by Jyntrel.
In a coffee machine, the filter sits on the water line between the supply and the brew group. It does not move air; it treats the water that will later become steam, hot water or extraction flow. The relevant operating conditions are therefore hydraulic: a working pressure range of 20–120 psi (approximately 1.4–8.3 bar) and a water temperature of 2°C to 38°C. The filter is for cold-water filtration only and should not be exposed to hot water upstream.
Within that range, the filter behaves like a low-pressure drop element. As water passes through the carbon bed and the resin, contact time determines how much chlorine and hardness is removed. Higher flow rates shorten that contact time, so if your machine draws water quickly, the filter should be sized so that the flow through the cartridge stays within the design envelope. The micron rating is achieved by fine pore interception that captures sand, rust and other large particles before they can reach the boiler or the brew valve. In hard-water areas, the ion exchange resin is the component that limits scale build-up on heating elements and in the hydraulic circuit.
The filtration medium is a combination of high-quality coconut shell activated carbon and food-grade ion exchange resin. The carbon reduces chlorine and off-flavours that would otherwise carry through to the cup; the resin targets the calcium and magnesium ions that form scale. Together they support a cleaner extraction and help protect the machine's hydraulic components from blocking and scaling over time.
Rated filter life is approximately 250 litres or 2–3 months, whichever comes first, depending on local water quality and usage frequency. In practical terms, a busy commercial site should plan replacement on the volume side, while a low-volume office or home setting may reach the time limit first. The cartridge is designed as a direct replacement for KEURIG-compatible machines, with dimensions engineered for a seamless fit.
To recommend the right configuration, we need the device model or a drawing of the filter housing, the target flow rate or daily water volume, the water temperature and pressure at the filter inlet, and the local water hardness if available. For OEM projects, we can customise the filter media ratio to suit different water qualities, adjust dimensions and structure for other coffee machine platforms, and apply your logo and packaging. Jyntrel has developed more than 1,000 filtration solutions over 20 years, and our team can support custom formulations based on the water profile of your target market.

In each case, the filter is selected against the machine's water draw and the local water analysis, not against a single universal specification.
Jyntrel operates multiple automated production lines with a monthly capacity of millions of pieces, which supports stable supply for brand owners and chain purchasers. We have more than 20 years of experience in filtration research and manufacturing, and we have been exporting to Europe, the United States, Japan and South Korea for over 20 years. Our production base covers 50,000 m², including 6 clean rooms totalling 20,000 m², where water-contact products are made in a controlled environment.
Our in-house laboratory is CNAS-accredited and can issue test reports on filtration performance and related parameters. The company holds ISO 9001, ISO 14001 and ISO 45001 certifications, and in 2024 we added IATF 16949 certification. Quality control runs through IQC, IPQC and OQC stages, with key parameters checked for batch consistency. Products comply with REACH and RoHS requirements, and compliance documents can be provided. Our address is Zhongshan, Guangdong, China.
To move from specification to a quotation, send us the device or vehicle model, the filter size or a drawing, the required airflow or water flow, the operating conditions (pressure, temperature, water hardness) and your target quantity. Our team will respond with a configuration proposal and lead time. Contact us to start the conversation.
The filter is rated for 20–120 psi (1.4–8.3 bar) and cold water at 2°C–38°C. At higher flow rates, contact time with the carbon and resin is reduced, so the cartridge should be sized so that the flow through it stays within the design envelope. Share your machine's flow rate and we can confirm the suitable configuration.
We need the inlet pressure and temperature, the daily water volume or flow rate, the local water hardness if available, and the device model or a drawing of the filter housing. With these details we can recommend the media ratio and cartridge size. For OEM projects, we can also adjust the formulation to the water profile of your target market.
Rated life is approximately 250 litres or 2–3 months, whichever comes first, depending on local water quality and usage frequency. High-volume sites may reach the volume limit first, while low-volume sites may reach the time limit. We recommend monitoring both.
Yes. Jyntrel offers OEM/ODM services covering dimensions and structure for different coffee machine platforms, filter media ratio, logo and packaging.
