Water is the main element flowing through our systems. The filtration of drinking water (and also of plant water) is not only recommended but also mandatory. The Viessmann DFR filter series is an excellent starting point. These are manual self-cleaning drinking water filters with a synthetic filter material. The porosity of the filter is 90µm at the bottom of the mesh and 125µm at the top. The filter is available in 3 different sizes, 3/4″, 1″ and 1 1/4″, all with 360° swivel flange connections.
