Re-read the statement about how stomach acid can handle many of these pathogens, but the upper sinus is not designed to do that. We are specifically talking about NOT using tap water for SINUS RINSES. Do you follow?
I have my own life experience with contaminated water that killed my mother a number of my friends and almost me. I learned my lesson.
But, by all means, use that tap water up into your sinuses unboiled and straight out of the bathroom sink. Don't spend a buck fifty for a bottle of distilled. It's your life. I'll choose differently, because I know better.
