The RainDance Water Saver Alkaline pH Boost Reverse Osmosis System

4-Stage 75gpd Low Waste High Recovery Drinking Water Filter

The RainDance Alkaline series offers multistage prefiltration followed by a revolutionary high recovery RO membrane to remove a multitude of contaminants from your water, including but not limited to: arsenic, barium, chromium, copper, lead, nitrate, sulfate, sodium, and chloride. This RO membrane provides a purified, clean slate to allow the post alkaline stages to shine and provide enhanced pH and ORP for great-tasting and healthful water. The RainDance Alkaline series purifies contaminants, remineralizes with calcium and magnesium, raises pH, energizes, and enlivens your water to give it the taste and feel that one would experience drinking from a mountain stream.

These compact state-of-the-art reverse osmosis drinking water filters provide superior water quality, eliminating the cost and inconvenience of bottled water, while saving up to 4 times the water of conventional drinking water RO systems. Standard under-the-counter RO drinking water filters will drain up to 4-7 gallons of water for every gallon of purified water made, but the new Pentair GRO Membranes are specially designed to save water and provide an incredible 1:1 product to waste ratio. Put that on top of our specially designed undersink system and you've got the ultimate solution for clean drinking water!
