I also read where the distilled water should be less than 1.0 for quality CS.
I'm actually measuring uS with my Hanna PWT meter. The instructions say the conductivity in distilled water should be less than 2.0 to 3.0 uS. Then it is suitable for Colloidal Silver
I have a distiller, but I could buy water from Walmart that was only .05. Mine put out 1.5. Plus in the summer time, the distiller added to the heat in the house, and if you didn't make it continually the charcoal filter which gets out the chlorine could get moldy and need to be replaced often which added to the cost of making it.
I use the distiller for most of my drinking water and I dislike hauling water from the store. I don't use the charcoal filter as it seems to raise the conductivity a little. Charcoal filters are designed to absorb chemicals that will evaporate with the boiling water in the kettle. I figure their shouldn't be extreme amounts of contamination in public water.
In the winter or at night it helps to heat up the house a little.
