Product review (5 stars): Helps Keep Humidifiers Cleaner
I love this product because it's helps to make the cleaning easier on all of my humidors.  I've also noticed that the filters don't turn a funny color when I use this, so pinkish bacteria lines - yay!  I've been using this product for several Winter seasons, but this one bottle usually last for an entire Winter and we have 3 humidfiers.
