The Deluxe 9.0 and Deluxe 9.5 both utilize a 380 watt SMPS-Transformer power supply and this increase in power is a key difference behind the generation of stronger, more negatively charged antioxidant production. The Deluxe 9.5 is the only machine in the Air Water Life line to feature Antioxidant Boost Technology, which increases the production of hydrogen at the drinkable pH 9.5 level from .75 ppm in the 9.0 to 1.5 ppm in the 9.5 – two times more molecular hydrogen! Diatomic Hydrogen is a building block of our bodies and acts as an extremely strong antioxidant to help keep our bodies healthy and energetic. The Deluxe 9.5 also boasts the ability to use the LED faucet, while the Deluxe 9.0 does not. Lastly, the Deluxe 9.5 carries unlimited lifetime cleaning which includes a full cleaning, re-calibration and replacement filter for your machine ($99 value).
