Medical journal studies, it has been reported, have shown that CS is effective in killing over 650 different pathogens. I guess most all of us on the list concur with that. We have all read this as promoted by numerous sites marketing CS. Now with all scientific controls used in the studies and other considerations aside... I would ask, at what PPM has this been conducted? As for myself, I use CS...and have seen positive results in its' use. However, to cut through the hype (if there is any)...does a blanket statement of efficacy for CS killing 650 pathogens apply to product in the 5-10 PPM range ie., that which is typically sold or made at home with users generators? Is there any substantial correlation in its' effectiveness in this range? Thanking you for any clarification on this, John
