Warning for Neti Pot Users

Some of you may have seen this article (or this one) about two deaths attributed to neti pot usage. Of course, it was the water they used that was the culprit, not the method or neti pots themselves. But it is kind of scary. So, a word to the wise on this matter: If you use a neti pot (and I have repeatedly recommended them for allergies, colds, and sinus infections), don't use tap water. Instead, use filtered, distilled, or purified water, as the above articles specify. I've recently made this change myself, just to be extra careful, even though I prefer warm, not lukewarm, water.
