Reverse Osmosis (R/O) is a water purification technology that removes dissolved solids from drinking water. Dissolved solids are small organic and inorganic particles that are suspended in water. Dissolved solids vary by location, but include chemicals like salts, calcium, and phosphates. Water with high total dissolved solids (TDS) levels often appear cloudy and can have “off” odors. Quench recommends reverse osmosis filtration for customers who rely on well water or have tap water with TDS levels of 400 ppm or higher. R/O technology is standard on the Quench 810 and Quench 940, and optional on all other coolers. All R/O-equipped water coolers require a drain line.
