Many Ozone Generators are producing Ozone at a 3% concentration. Besides, hardly achieving 30% of total ozone dissolved and wasting incredibly large amounts of Oxygen. There is a much better way to dissolve Ozone in water. The NANO can dissolve up to 70% of total Ozone produced while using incredibly low amounts of Oxygen (4 SLPM). That`s more than Double the Ozone dissolved, Imagine replacing two expensive inefficient clunky Ozone Generators with one Sleek, Compact NANO Ozone Generator.
