Swiss AOS 7135 1.8 Gallon Humidifier

I bought this humidifier because it requires no filters and produces a mist which I like. It does have a water filter but if you have good water you don't need to use. Because it does not have a wick filter, you will need to clean it at least once every few months. The disadvantage of mist humidifiers is that if you live in the city or you have hard water, you will get white dust. Since there is no filter, the salt and minerals have to go somewhere....
