The UltraStream is designed to supply a family of 4 each with 2 liters of water per day for a complete year. That's about 3,000 liters (800 gallons) a year.
It's not designed to run continuously outputting normal levels. The water needs to have some time in contact with the media. Fill a couple of liters and wait for maybe 20 minutes. Fill another 2 liters.The electronic ionizers do output levels continuously but has 3-times less hydrogen and 1/10th the filtration than UltraStream. This is one of the great strengths of the UltraStream.
