This coffee machine filter cartridge is a water-purifying filter compatible with BLACK & DECKER coffee machines, designed to reduce chlorine, sediment, and scale from the water supply before it reaches the brewing path. It combines coconut-shell activated carbon and food-grade ion-exchange resin to protect heating elements and maintain coffee flavour. It is intended for household and commercial coffee equipment, as well as OEM water-filter programmes. The product is manufactured by Jyntrel, a filter specialist based in Zhongshan, Guangdong, China.
Although this is a water filter, its performance is governed by flow path and operating conditions in the same way an air filter is. The cartridge sits on the cold-water inlet side of the coffee machine, where line pressure typically ranges from 20 to 120 psi (about 1.4 to 8.3 bar) and water temperature stays between 2°C and 38°C. Within this envelope, the composite media bed intercepts particulate matter and dissolved contaminants as water passes through.
Flow velocity matters: higher flow rates shorten contact time with the activated carbon and ion-exchange resin, which can reduce contaminant removal efficiency. The filter is therefore specified for cold-water service only, and it is not intended for hot-water lines or steam circuits. In systems where inlet pressure fluctuates, a pressure-regulating valve upstream is recommended to keep the cartridge within its rated range and to avoid mechanical stress on the housing.
The filter’s internal flow path is designed to distribute water evenly across the media, limiting channelling and making full use of the carbon and resin capacity. For OEM projects, the inlet and outlet geometry can be adapted to match the host appliance’s connection points, provided the operating pressure and temperature limits are respected.
The cartridge uses a fine microporous structure to intercept sediment, rust, and other large particles, while the coconut-shell activated carbon adsorbs residual chlorine and odours that affect taste. The food-grade ion-exchange resin reduces hardness minerals, which are the primary cause of scale build-up in coffee-machine boilers and thermoblocks. By limiting scale, the filter helps maintain consistent brewing temperature and extends the service life of the heating components.
Rated filter 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 commercial settings, replacement may be required sooner. The filter operates within a pressure range of 20–120 psi and a temperature range of 2°C–38°C, and it is designed for cold-water filtration only.
Because the media are matched to the application, the filter supports the flavour profile of the brewed coffee by removing chlorine and organic odours without stripping desirable minerals. This balance is particularly relevant for espresso and filter-coffee equipment, where water chemistry directly influences extraction.
To recommend the correct cartridge or to develop an OEM version, we need the following information: the coffee-machine make and model, the connection size or a drawing of the filter seat, the required flow rate or daily water volume, the operating pressure and temperature at the inlet, and the target market’s water hardness. Please also state your expected order quantity and whether you need private-label packaging.
Jyntrel supports OEM and ODM projects with customisation of dimensions, housing structure, filter-media grade, logo, and packaging. More than 1,000 filter solutions have been developed across applications, and our engineering team can work from a drawing or a physical sample. New tooling and development typically take 30–45 days, depending on complexity.

This cartridge is used in automatic coffee machines, semi-automatic espresso machines, and commercial coffee equipment where water hardness and chlorine levels affect both taste and machine reliability. It is also suitable for OEM programmes: appliance brands and water-filter distributors can specify the cartridge under their own branding, with packaging and documentation adapted to the target market.
In commercial settings such as cafés and offices, the filter helps protect boilers and reduce descaling downtime. For household machines, it offers a simple way to improve water quality without installing a separate under-sink system. The cartridge is not intended for hot-water or steam applications, and it should be installed only on the cold-water supply.
Jyntrel operates multiple automated production lines with a monthly capacity of millions of pieces, supported by more than 20 years of export experience to Europe, the United States, Japan, and South Korea. This capacity and export record underpin stable supply for long-term programmes.
The 50,000 m² plant in Zhongshan includes six clean rooms totalling 20,000 m², where filter assembly and handling take place under controlled conditions. Our in-house laboratory is CNAS-accredited and can issue test reports on filtration efficiency, dust-holding capacity, and resistance; for this water filter, flow and pressure testing are part of the quality routine.
Quality management is built around IQC, IPQC, and OQC checks across the production flow. The company holds ISO 9001, ISO 14001, and ISO 45001 certification, and obtained IATF 16949 in 2024. Products can be supplied with REACH and RoHS compliance documentation where required.
To move forward, please send the following details: your coffee-machine model or a drawing of the filter interface, the required size, the flow rate or daily water volume, inlet pressure and temperature, and your expected order quantity. If you are developing a private-label product, include your packaging and logo requirements. Our team will respond with a specification proposal and, where applicable, a sample plan.
You can reach us through the contact page. Jyntrel’s engineering and sales teams will review your operating conditions and recommend the most suitable configuration for your application.
This is a water filter, so air velocity does not apply. The relevant flow parameter is water flow rate: higher flow reduces contact time with the carbon and resin, which can lower efficiency. For best performance, keep the flow within the range agreed for your machine model, and operate within the rated pressure of 20–120 psi.
For this water filter, we need water flow data rather than airflow: the required flow rate or daily water volume, inlet pressure, and water temperature. Please also provide the coffee-machine model and connection size or drawing. With these details we can confirm the appropriate cartridge or propose a custom configuration.
Yes. The ion-exchange resin reduces hardness minerals that cause scale, and the activated carbon addresses chlorine and odours. In very hard water, filter life may be shorter than the rated 250 litres or 2–3 months. We recommend sharing a water analysis so we can advise on replacement frequency.
The cartridge is developed to match the dimensions, connections, and filtration specifications of the compatible BLACK & DECKER models. We recommend confirming the exact model before ordering, and we can supply samples for fit verification. For other brands, please provide the model and interface drawing.
For standard compatible models, the MOQ is 5,000 pieces, with lead times of 15–20 days for stock or small batch orders. For OEM customised versions, the recommended MOQ is 10,000 pieces, and production including tooling and packaging development typically takes 25–30 days.
Yes. For standard models we can provide free samples (freight collect), usually shipped within 3–5 working days. For custom projects, we provide prototype, engineering, and production samples for staged approval. Test reports and material declarations can be included with the samples.
Replace the cartridge at approximately 250 litres or every 2–3 months, whichever comes first. Actual interval depends on water hardness, chlorine level, and usage frequency. In commercial or high-volume settings, more frequent replacement may be needed to protect the machine.
The standard cartridge is rated for 20–120 psi and 2°C–38°C, cold water only. If your inlet pressure or temperature is outside this range, contact us with the details; we can discuss alternative configurations or recommend upstream regulation. Please do not exceed the rated conditions, as this may affect performance and safety.
