Celrith coffee machine filter cartridges are designed to reduce waterborne impurities that affect both equipment reliability and coffee taste. They filter out sediment, rust, chlorine, odour, scale-forming hardness minerals and heavy metals from the water supply. The cartridge is a drop-in replacement for BREVILLE coffee machines, intended for brand owners, distributors and service companies that need a reliable, compatible water filter.
Water used in coffee machines is rarely pure. Even municipally treated water can carry residual chlorine, fine sediment, rust particles and dissolved calcium and magnesium. Chlorine and organic matter affect aroma and flavour, while hardness minerals precipitate as scale when water is heated. Over time, this scale builds up on heating elements, sensors and valves, reducing flow and forcing the machine to work harder. In offices, cafés and homes with hard water, the problem accelerates, leading to blocked spray heads, inconsistent extraction temperatures and, eventually, costly repairs or downtime.
For commercial settings, the cost of scale is not limited to maintenance. It shows up in energy bills, in the number of service calls per machine per year, and in the consistency of the coffee served. A filter that addresses these contaminants early protects the entire system.
Scale acts as an insulating layer on heating elements, so the machine draws more power to reach the same temperature. Pumps have to overcome higher resistance as flow paths narrow. Valves and solenoids can stick or fail. In machines with electronic sensors, scale can cause false readings and error codes. The cumulative effect is reduced machine life and more frequent service interventions.
Sediment and rust particles add another layer of risk. They can clog fine orifices, score internal surfaces and interfere with seals. In hard-water areas, the combination of scale and particulate load can cut the effective life of an unprotected machine significantly. For businesses that rely on coffee service, every unplanned downtime event has a direct cost. Filtering the water before it enters the machine is the most effective way to reduce this load.
The Celrith cartridge combines high-quality coconut-shell activated carbon with food-grade ion exchange resin. The activated carbon adsorbs chlorine, off-flavours and organic compounds, improving the taste and aroma of the coffee. The ion exchange resin reduces hardness minerals, the primary cause of scale, and also helps to lower heavy metal content. Fine microporous interception captures sediment and rust particles before they can reach sensitive components.
This multi-stage approach addresses both the aesthetic and the operational side of water quality. The result is water that supports consistent extraction and protects the machine from scale-related wear. The cartridge is designed to match the dimensions and connection of the original BREVILLE filter, so replacement is straightforward and requires no adapters or modifications.

Celrith filter cartridges are used by coffee machine brand owners, importers and distributors, and commercial service providers. They are suitable for automatic and semi-automatic espresso machines in cafés, offices, hotels and homes, particularly in areas with hard water. The cartridges are also used by OEM customers who require a private-label water filter for their own coffee machine range. Because the cartridge is compatible with BREVILLE machines, it offers a direct replacement option for aftermarket channels and service networks.
Celrith products are manufactured in a facility that holds ISO 9001, ISO 14001 and ISO 45001 certifications. The company also achieved IATF 16949 certification in 2024. Products comply with REACH and RoHS regulations, and compliance documents are available on request. The on-site laboratory is CNAS-accredited and can issue test reports for filtration efficiency, dust holding capacity and resistance. The manufacturing base covers 50,000 m², including six cleanrooms totalling 20,000 m², which support contamination-free production. With more than 20 years of experience in filtration and exports to Europe, the US, Japan and South Korea, Celrith provides stable supply and full quality control from incoming materials to final inspection.

It reduces chlorine, off-flavours, organic compounds, scale-forming hardness minerals, heavy metals, sediment and rust. The coconut-shell activated carbon adsorbs chlorine and organics, while the ion exchange resin lowers hardness and heavy metal content. Fine microporous interception captures particulate matter.
By reducing calcium and magnesium ions, the ion exchange resin limits the formation of scale on heating elements and internal passages. This helps maintain flow and heat transfer efficiency, reducing the risk of blockages and service calls. The cartridge is designed for cold water filtration only, with an operating temperature range of 2°C to 38°C.
Yes, it is designed to match the dimensions and connection of the original BREVILLE filter, allowing drop-in replacement without adapters. Each batch is checked for fit and performance in our CNAS-accredited laboratory. For OEM projects, we can also customise dimensions and connections to suit other machine models.
The cartridge has a rated life of approximately 250 litres or 2–3 months, whichever comes first. Actual life depends on local water hardness and usage frequency. In hard water areas, replacement may be needed more often to maintain protection.
Yes, samples are available. For standard specifications, we can provide free samples with the customer covering international courier costs. Customised samples are evaluated based on tooling and development costs, which can be credited against a bulk order. Samples are typically dispatched within 3–7 working days and include a performance test report from our CNAS-accredited laboratory.
The MOQ for standard compatible models is 5,000 pieces, with a lead time 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 takes about 25–30 days. Monthly capacity is in the millions of pieces, supporting large-volume programmes.
Yes, we provide full OEM/ODM services including custom dimensions and structure, filtration media formulation, logo printing, retail packaging and multilingual instructions. Our engineering team can develop a custom solution within 7 working days. With over 1,000 filtration solutions developed, we can tailor the cartridge to your market requirements.
Our coffee machine water filter cartridges are certified to NSF drinking water component standards and comply with US EPA and European drinking water contact material regulations. The materials used are food-grade. The company holds ISO 9001, ISO 14001 and ISO 45001 certifications, and achieved IATF 16949 and medical supplies GMP certification in 2024.
