Everpure MR-20 is a Mineral Reduction Cartridge that can improve the equipment's life and performance by removing at least 90% of all dissolved solids using Reverse Osmosis Separation Technology. It is particularly useful on low capacity steamers, warmers, small steam boilers, and other evaporative equipment that are not emptied each day. By limiting limescale build-up, the MR-20 cartridge helps reduce excessive machine downtime and maintenance costs. The sanitary cartridge replacement is quick, clean, and simple, with internal filter parts never exposed to handling or contamination.
