mpressive 10,000 litre filter providing an excellent partner to the large and more heavily used machines. The built in lime scale inhibitor allows the MH4P to deal with hard water with ease. With a quick change head and an automatic shut off valve designed to give the engineer a smooth filter change and install, the MH4P filter is simplicity to use and install. The MH4P filter works up to 300ppm hard water and therefore excels against its competitors which claim their capacities at 180ppm. The MH4P has a service life of 6-12 months dependent on the water hardness, location of the filter and its usage, though for performance and taste we would recommend a filter change every six months. Free quick change head included further reducing costs. The MH4P is compatible with the Everpure QL3 single head.
