I just have a concern with some available published material regarding ion/particle ratio is all. I just believe more information should be included for the man/woman in the street to make better determinations regarding ion/particle ratio's, nothing more, nothing less.


I always thought that if my finished EIS was about 12-15 uS and had very faint Tyndall with no large sparklies, then it probably fit into the 85-90 % ionic, 10-15% very small particles range.
