This Thesvin coffee machine filter cartridge is a drop-in replacement compatible with BREVILLE espresso machines. It filters cold water to reduce chlorine, odour, scale-forming hardness and heavy metals using a coconut-shell activated carbon and food-grade ion-exchange resin blend. It is designed for automatic, semi-automatic and commercial coffee machines, and for OEM water-filter programmes where dimensional match and sealing are critical.
Fitment drives the design. The cartridge is built to the same envelope and connection geometry as the original BREVILLE filter, so it seats into the machine's filter holder without adapters. The outer diameter and overall length match the host receptacle, and the connection end mirrors the original interface so the water path is unchanged. Sealing relies on the cartridge's own structure compressing against the holder, exactly as the original part does; no additional seals or clips are required.
Because the interface is form-matched, installation follows the same steps as the original: remove the old cartridge, rinse the new one, insert it into the holder until it locates, and flush as directed by the machine manual. There is no need to modify the water circuit, change tubing or adjust the brew path. For OEM customers, the same fitment approach applies to custom holders: we work from your drawing or a physical sample to match the locating features, inlet/outlet position and overall dimensions.
The cartridge is intended for cold-water filtration only. Operating temperature range is 2°C to 38°C, and operating pressure range is 20–120 psi (approximately 1.4–8.3 bar), which covers typical mains and pumped coffee-machine supply conditions.
The filtration medium combines high-quality coconut-shell activated carbon with food-grade ion-exchange resin. The activated carbon adsorbs residual chlorine, organic compounds and off-flavours that can mask coffee aroma; the ion-exchange resin reduces calcium and magnesium ions that cause scale, as well as certain heavy metals. Fine microporous interception captures sediment, rust and other large particles before they reach the brew circuit.
The result is water that supports consistent extraction and helps protect the machine's boiler and valves from scale build-up. The cartridge is not intended to soften water to zero hardness; it reduces hardness to a level that helps extend equipment life while maintaining the mineral balance that many espresso profiles rely on. For commercial soft-water applications, the same cartridge can be specified as part of a multi-stage water treatment layout.

Thesvin operates a 50,000 m² manufacturing site in Zhongshan, Guangdong, China, including six cleanrooms totalling 20,000 m². Production is controlled under ISO 9001, ISO 14001 and ISO 45001, and the site achieved IATF 16949 certification in 2024. Incoming materials, in-process parts and finished cartridges are checked through IQC, IPQC and OQC routines to maintain dimensional consistency from batch to batch. An in-house CNAS-accredited laboratory supports testing and can issue reports on filtration performance parameters.
Standard compatible cartridges typically ship within 15–20 days for stock or small-batch orders; OEM customised versions usually require 25–30 days after drawing and packaging approval. Minimum order quantity is 5,000 pieces for standard compatible models and is recommended at 10,000 pieces or more for OEM customisation. Multiple automated production lines support monthly output in the millions of pieces. Products comply with REACH and RoHS requirements, and compliance documents can be provided. The company has more than 20 years of filtration product development and manufacturing experience, with continuous exports to Europe, the United States, Japan and South Korea, and has developed over 1,000 filtration solutions.
To get a precise quotation, tell us the device or vehicle model, the cartridge size or a drawing, the required water flow, the operating pressure and temperature, and the order quantity. If you do not have a drawing, send an old part or clear photos with dimensions, and we will match it. Contact our team to start the fitment check and sample request.
The cartridge is designed to the same dimensions and connection geometry as the original BREVILLE filter, so it seats into the machine's filter holder without adapters. It operates within 20–120 psi and 2–38°C, covering typical coffee-machine supply conditions. To confirm, send us your machine model or a photo of the old cartridge.
Yes. If you do not have a drawing, you can send an old cartridge or clear photos with key dimensions. Our engineering team will compare the interface and overall envelope against our existing tooling or prepare a custom match. This is often the fastest way to confirm fitment for older or less-documented machines.
The coconut-shell activated carbon and ion-exchange resin reduce residual chlorine, odours, scale-forming calcium and magnesium, certain heavy metals, and fine microporous interception captures sediment and rust. Performance is validated in our CNAS-accredited laboratory. For project-specific efficiency data, request a test report with your sample.
Replace it at approximately 250 litres or every 2–3 months, whichever comes first, depending on local water quality and usage frequency. Hard water or heavy daily use may shorten the interval. Consistent replacement helps protect the boiler and maintain coffee flavour.
Yes. For standard compatible cartridges, we can provide free samples with the customer covering international courier costs. For customised versions, sample costs depend on tooling and development and can be credited against a bulk order. Samples usually ship within 3–7 working days and can include a performance test report from our CNAS-accredited laboratory.
The MOQ is 5,000 pieces for standard compatible models, with a typical lead time of 15–20 days for stock or small-batch orders. For OEM customisation, the recommended MOQ is 10,000 pieces or more, and production usually takes 25–30 days after drawing and packaging approval.
Yes. We support customisation of dimensions, housing structure, filtration media grade, logo and retail packaging. Our engineering team can work from your drawing or a sample and typically provides a customisation proposal within 7 working days. With over 1,000 filtration solutions developed, we can adapt the cartridge to different machine models and water conditions.
Production conforms to ISO 9001/14001, IATF 16949 and medical supplies GMP standards, with CNAS national-level testing certification. Products comply with REACH and RoHS, and compliance documents can be provided. Please contact us with your target market requirements to request the relevant files.
