Product review (5 stars): Works great
I don't know whether it's the only reason, but it turns out that there's nothing to be cleaned in my Crane drop humidifier. No orange stuff or anything left in weeks. I normally use tap water, and occasionally use filtered water from Brita pitcher. So I assume this bottle works. I'm so happy that I don't need to clean my humidifier in several weeks. Although I'm supposed to clean it more often, I really don't see anything to clean.
