Using the patent pending HTETech, Letus SuperWater machine can create very high level of alkaline water without the help of electrolyte solution. To obtain alkaline water at such high level as Letus SuperWater, other machines on the market use electrolyte solution, namely salt. Doing this would allow the final water to achieve high level of alkaline, but this also creates Sodium Hydroxide (NaOH), which is not good for our health.
