This is just scary. Silver lungs does not divulge what the chemical is they sell you to use. The claim is that the chemical changes the PH to 10.
Logic would say you would want to be as close to perfect human PH as possible. That is NOT 10 it is 7.4.
They claim it converts ionic to colloidal???
They are not the same thing. You want electrically charged silver which is ionic. The more ionic the better. Colloidal refers to the size of the silver particles and not the state of being charged. (This looks like a smoke screen)
Your goal is to get the purest water silver solution possible. This chemical additive sounds dangerous. But I am a true newbie at this stuff. I think you should do more research.
Please read the papers Grizz refers to in the above posts.
Meso Silver sells a nebulizer.
