• Highest flow rates and the most efficient system in the industry!
• Lowers parts per million (ppm) of total dissolved solids (TDS) by 95%+
• SAVE MORE WATER by running a 1:1 waste to product water ratio
• Includes ChloraShield™ carbon filter for 100% chloramine removal

• NEW AND IMPROVED Ultra-Efficient Dry Membrane
• Reduces 95%+ of total dissolved solids (TDS)
• 20% Increased Flow Rate
• Filters 600+ gallons per day (GPD)
• Replace between 6 months–2 years

Flow rates of RO systems are based on source water @ 65 psi / 77° / 500 ppm

RO output depends on the source water temperature. At 77°, the system should produce 100% of the rated output. As the temperature drops or increases, so does the output
