Why not use the Collgen Ionic Silver Hydrosol generator that was developed for NASA. They use it for decontamination and the pilots drink it all the time. Drink up! I have one. Collgen2 makes many gallons and not a rip off unproven Science like these cheap things. My doctor had me purchase one from the inventor. Saved my daughter's life who was confirmed H1N1. Why does the government use it? Fred Peschel made sure he left the personal size one for the people.collgen2
