All I use is the Colloidal Silver in an ultrasonic humidifier and it cured my pneumonia, also for the 1st time in many decades I have gone through a winter without my usual severe chest cold, and no colds of any kind. I make my own Colloidal Silver 1 gallon at a time using the Silvertron Elite: https://www.youtube.com/watch?v=lOKnp9Y54Ls
My bedroom ultrasonic humidifier uses 1/2 gallon per night.
