I've been using humidifiers in all of our bedrooms for years, but I detest cleaning them out. It is my least favorite chore. This year when I ordered my filters and picked up this stuff and it is great. You just add a little bit to the water well and it keeps everything clean. I use four humidifiers in my house and this stuff has lasted a few months and I still have some left. I expect to need about one bottle per season.
