We have to change this filter out every two - two and a half weeks as our well water is not good for us to drink. We use this water in our Kerig Coffee Machine....
This humidifier is quiet, fresh and calming. It has a extremely light misting, that can not be seen. The fan makes no sound. It is very refreshing and light airy. I use distilled water only, the directions state to use tap water. I used distilled water to prevent the white residue from getting everywhere. The only negative is it needs filter replacements, that's the only reason it got four stars and of course the cost of the distilled water, which tit uses at least a gallon of water bottle a day, about 89 cents a gallon daily, just for the water cost and then the filter replacement, I did not know this until it arrived, but I guess I will keep it anyway. I like it just that much. I would recommending purchasing. I do not feel like the hassle of returning, I guess we will keep it.
