Bests & Worsts Reviews from Amazon

Very simple and easy to use. About the black particles that develop in the water after use, I found the following explanation to be helpful: "A Vaporizer produces moisture by heating small amounts of the minerals in the water using tiny electrodes in the shaft of the unit. The minerals then heat the water to a boil and release steam into the air. The minerals will then settle to the bottom of the tank, possibly becoming small black flakes. These flakes are normal and should be rinsed out when you refill the tank. Any bacteria or mold in the water will be killed by the temperature of the water."
