Max 10 gpm Oneflow+Oneflow+ logo, water filterlogo, water filter What to Know OneFlow+ does not reduce silica scaling. While silica tends to have a less significant effect on scale formation than other minerals, it can act as a binder that makes water spots and scale residue outside the plumbing system difficult to remove. Water known to have heavy loads of dirt and debris may require pre-filtration prior to OneFlow+ OneFlow + Water Filtration System Salt-Free Scale Prevention PLUS Water Filtration OneFlow+ prevents hard water scale buildup in pipes and appliances and removes harmful contaminants for better tasting water. OneFlow+ uses a unique technology called Template Assisted Crystallization (TAC), which attracts and converts dissolved water hardness minerals into microscopic crystals. These crystals flow harmlessly through the plumbing system to the drain, keeping your pipes and appliances free of scale. Great Tasting Water at Every Tap Rated to 20 microns, the integrated high-capacity radial flow carbon block filter reduces chlorine, bad tastes, odors, and other harmful contaminants for great tasting, clean water. Good for the Earth An increasing number of municipalities ban the use of traditional water softeners due to the high salinity of the wastewater. With zero wastewater to drain, OneFlow+ is helping to meet those guidelines. Whole House Water filter. Carbon Filter + Scale filter. Whole house filter OneFlowPlus Water Filtration System.
