This Ranveth coffee machine filter cartridge is a compatible replacement for BLACK & DECKER coffee machines, designed to reduce chlorine, odours, heavy metals and scale from tap water. It pairs coconut-shell activated carbon with food-grade ion-exchange resin, so each layer targets a different contaminant while keeping flow resistance low. The cartridge suits household automatic and semi-automatic espresso machines, commercial soft-water setups, and OEM water-filter programmes.
The performance of a coffee filter comes from how its media are matched, not from any single material. In this cartridge, coconut-shell activated carbon is paired with food-grade ion-exchange resin. The carbon's fine microporous structure adsorbs residual chlorine and organic odour compounds that would otherwise flatten aroma, while the resin exchanges calcium and magnesium ions to lower temporary hardness and reduce limescale build-up in the brew path and heating element.
Because the two media work by different mechanisms, their ratio and sequence matter. Placing carbon and resin in a balanced composite lets the cartridge deliver taste improvement and scale control without excessive pressure loss. That balance also supports a rated life of about 250 litres or 2–3 months, depending on local water quality and use frequency. For buyers, the practical result is a cartridge that maintains flow across its service interval and protects the machine's hydraulic components.
The fine microporous structure also intercepts larger suspended particles such as sediment and rust, so downstream media are not prematurely loaded. This layered approach is why the cartridge can serve both taste-sensitive espresso applications and general coffee-machine water treatment within the same 2°C–38°C cold-water operating range.

The cartridge is built for coffee equipment where water quality directly affects cup profile and machine reliability. Typical installations include fully automatic coffee machines in homes and offices, semi-automatic espresso machines where scale control protects the boiler and group head, and commercial coffee-machine soft-water setups in cafés and food-service outlets. Because the media are food-grade and the housing is designed for drop-in compatibility, the same platform is also used in OEM water-filter programmes, where a brand needs a private-label cartridge matched to its machine interface.
It is not intended for hot-water lines or for water outside the stated 2°C–38°C range. For high-hardness supply, a pre-filter or a different resin ratio can be discussed during specification.
To quote accurately, we need the device or vehicle model, or a drawing with key dimensions and connection details. Please also state the required flow rate or water flow, the operating pressure and temperature, and the expected replacement interval. Quantity per order and per year helps us confirm MOQ and scheduling. If you have a target market, include any labelling or packaging requirements. Send these details through our contact page and our engineers will respond with a specification proposal.
Our in-house laboratory is CNAS-accredited, so media choices are backed by test reports for filtration efficiency, dust-holding capacity and resistance. Production runs in a 50,000 m² plant that includes six cleanrooms totalling 20,000 m². The factory holds IATF 16949 (achieved in 2024) and ISO 9001, ISO 14001 and ISO 45001 systems. Products comply with REACH and RoHS, and we can supply compliance documentation. With more than 20 years of filtration experience and exports to Europe, the US, Japan and Korea, we support OEM/ODM projects covering dimensions, structure, media grade, logo and packaging. Our location is Zhongshan, Guangdong, China.
For standard models, samples can be arranged so you can verify fit and flow on your target machine. For custom builds, we provide prototype, engineering and production samples in stages. To start, tell us the device model, required size or drawing, flow or water-flow requirement, operating conditions and order quantity via /en/contact. We will reply with a quotation and lead time.
It uses coconut-shell activated carbon paired with food-grade ion-exchange resin. The carbon adsorbs chlorine and odours, while the resin reduces hardness to control scale. This combination supports a rated life of about 250 litres or 2–3 months.
Pairing carbon with resin lets each medium target different contaminants without excessive pressure loss. The composite structure maintains flow within the 20–120 psi operating range. This balance helps keep brewing performance stable across the service interval.
Yes, it is developed to match the dimensions, connection and filtration specifications of the original cartridge for the listed BLACK & DECKER models. We recommend confirming the exact model when requesting samples. Fit and flow can be verified before ordering.
Yes, we offer OEM/ODM customisation of media ratio, filtration rating, flow parameters, housing structure, logo and packaging. Custom projects typically require a drawing or sample for reference. Our engineers will propose a specification based on your water quality and machine requirements.
The MOQ for standard compatible models is 5,000 pieces, with a lead time of about 15–20 days for stock or small batch orders. Customised versions typically require a higher MOQ and a longer production cycle. Please confirm details with our sales team when you inquire.
Replace it after approximately 250 litres of water or every 2–3 months, whichever comes first. Actual life depends on local water hardness and usage frequency. In high-hardness areas, more frequent replacement may be needed.
Yes, samples are available for standard models so you can test fit and performance. For custom projects, we supply samples at each development stage. To receive a quote, please share your device model, required size or drawing, flow rate, operating conditions and quantity via our contact page.
It operates at 20–120 psi (approximately 1.4–8.3 bar) and 2°C–38°C, and is intended for cold-water filtration only. Do not use it on hot-water lines. If your supply pressure or temperature falls outside this range, contact us to discuss alternatives.
