This Thesvin coffee machine filter cartridge is a drop-in water purification filter designed for BLACK & DECKER coffee machines, replacing the original cartridge in the water tank or inlet line. It filters tap water through a coconut-shell activated carbon and food-grade ion exchange resin core, reducing chlorine, odours, heavy metals and scale-forming hardness. It is built for household, office and commercial coffee equipment where fitment, seal quality and stable flow matter. Thesvin manufactures it in Zhongshan, Guangdong, China, and supplies it as a compatible replacement and as an OEM/ODM project.
Fitment is the first thing to confirm. The cartridge is developed to the same dimensions and connection geometry as the original BLACK & DECKER filter, so it locates in the machine's filter seat without adapters. The housing seats against the matching receptacle, and the outlet port aligns with the water path so that flow passes through the media rather than bypassing it. During pre-production validation, every cartridge design is checked for assembly fit, flow and seal performance in the target machine before volume production.
Because the interface is dimension-driven, Thesvin asks for the machine model or a sample of the old part before quoting a custom variant. Small changes in diameter, length or port position can decide whether a cartridge seals correctly and stays seated under line pressure. The working pressure range is 20–120 psi (about 1.4–8.3 bar), and the cartridge is intended for cold water only, between 2°C and 38°C. If your machine operates outside these conditions, say so at inquiry stage so the fitment and media can be reviewed.
The filtration media combines high-quality coconut-shell activated carbon with food-grade ion exchange resin. The carbon stage adsorbs residual chlorine and organic odours that flatten coffee aroma, while the resin stage exchanges hardness ions to reduce calcium carbonate scale. Fine microporous interception also captures sand, rust and other large particles before they reach the brew path. The result is water that supports clearer flavour and helps protect the heating element and hydraulic parts from scale build-up.

Thesvin's quality system is built around dimensional consistency, because a cartridge that does not seat cannot perform. The plant holds IATF 16949 certification, obtained in 2024, and runs incoming IQC, in-process IPQC and outgoing OQC checks. Each batch is inspected for fit-related dimensions and flow performance before packing. The company also holds ISO 9001, ISO 14001 and ISO 45001 certification.
Testing is carried out in the company's own laboratory, which is CNAS-accredited and can issue reports on filtration efficiency, dust holding capacity and resistance. Production runs in a 50,000 m² facility in Zhongshan, Guangdong, China, which includes six clean rooms totalling 20,000 m². Standard compatible models typically ship in 15–20 days; custom projects run about 25–30 days. Thesvin has more than 20 years of filtration manufacturing experience and exports to Europe, the United States, Japan and Korea. Products meet REACH and RoHS requirements, and compliance documents can be supplied with the order.
To get an accurate quote, send the device model, a dimensioned drawing or the old cartridge, the required water flow, operating pressure and temperature, and the order quantity. Include packaging or branding requirements if the project is OEM. Our team will confirm fitment and respond with pricing and lead time. Contact Thesvin to start your inquiry.
Thesvin develops this cartridge to the dimensions and connection geometry of the original BLACK & DECKER filter, and each design is checked for assembly fit, flow and seal performance before volume production. Send your machine model or a photo of the filter seat and we will confirm compatibility. Free samples are available for fit testing on your unit.
Yes. A used cartridge is often the fastest way to confirm fitment, because it shows the exact seat, port position and length required. Thesvin can measure the old part and compare it with existing tooling or develop a new drawing for approval. Shipment of the sample part is at the customer's cost.
The coconut-shell activated carbon and food-grade ion exchange resin reduce residual chlorine, odours, heavy metals and scale-forming hardness, while fine microporous interception captures sand and rust. Rated life is approximately 250 litres or 2–3 months, whichever comes first, depending on local water quality and usage. Replacement intervals can be adjusted for your target market.
Yes. Standard models are available as free samples, usually shipped within 3–5 working days with freight paid by the customer. For custom projects, Thesvin provides prototype, engineering and production samples for staged approval. Quotes are issued after fitment and operating conditions are confirmed.
Standard compatible cartridges have an MOQ of 5,000 pieces and typically ship in 15–20 days. OEM/ODM projects have a recommended MOQ of 10,000 pieces, with a production cycle of about 25–30 days including tooling and packaging development. Monthly capacity reaches millions of pieces.
The cartridge is rated for 20–120 psi (about 1.4–8.3 bar) and 2°C–38°C, and is for cold water filtration only. If your machine runs outside these ranges, tell us at inquiry stage so the fitment and media can be reviewed. These limits apply to the standard compatible design.
Thesvin operates IQC, IPQC and OQC checks across the production flow, with batch inspection of fit dimensions and flow performance. The plant holds IATF 16949 certification obtained in 2024, and the company's own CNAS-accredited laboratory can issue filtration efficiency, dust holding capacity and resistance reports. Production takes place in a 50,000 m² facility with six clean rooms totalling 20,000 m².
Yes. Thesvin offers OEM/ODM service covering media grade, housing structure, filtration rating, flow and life, plus laser marking, logo printing and retail packaging. More than 1,000 filtration solutions have been developed, and new projects typically run 30–45 days for development.
