Depending on source water, the Aqua Ionizer Deluxe™ 9.0 produces water with a pH of between 3.5 to 11.5 alkaline. It also boosts the water's age-fighting antioxidant potential with a negative +1000 to -860 ORP. Each inner activated carbon filter cleans and treats 4,000 liters. 7 Optional Healthy Water Settings Produces pH 3.5 to 11.5 Alkaline Water Antioxidant potential 1000+ to -860 ORP Produces Over 12 pH Levels What's Included Carbon Water Filter Diverter Hardware Set Flexible Metal Spout Water Tubing Descaling Solution Wall Mounting Equipment pH Tester/Reagent With Color Chart (Value $29.95) Owner's Manual Product Specifications Dimensions: 8.3″ (L) x 4.3″ (W) x 12″ (H) Standing Weight: 13.0 pounds Installation: Counter Top Faucet Diverter Plate Quantity: 9 Plates, 163 square inches surface area Plate Design: Durable, energy efficient, multilayer, platinum-coated titanium Power System: Transformer Voltage: AC 110V/60Hz Wattage: 5w – 350w adjusting to source water Max.
