Product review (1 stars): Dangerous and Expensive
I was wondering why I just didn't feel well after a night of using my humidifier with this product in it.  I'd wake up feeling like I had bad allergies or a cold (head stuffed, nose clogged and a general, tired feeling).  Plus, I don't understand why this company charges so much.  It costs $6.99 in stores and on other websites. I think a drop or two of Calgon water softener might prove safer than this toxic product.
