The 3M Dual Flow Series Filter System provides consistent quality water by reducing particulate, chlorine taste and odor, and chloramine. Excess particulate can cause abrasion and short life on pumps, seals, o-rings, and valves, while excess chlorine and chloramine residual can cause unpleasant tasting beverages. Chloramine is known to be corrosive and can damage any equipment using water such as steamers, combi-ovens, coffee and tea brewers, and espresso machines. Our Sanitary Quick Change (SQC) encapsulated cartridge design allows for fast and easy cartridge change-outs without the need for a filter wrench.
