Love these humidifiers. I've bought 3 of the 2 Gal ones and this 1.5 Gal for my son's room. He has asthma and this works great for the dry winter air. I use the 2 Gal every night, while sleeping. I bought one as a gift and I use one for my Chameleons cage. They need a very humid, temp-controlled environment and this works way better than the humidifiers they market for terrariums. It's super quiet, holds a lot of water, lasts long between fillings, super easy to fill without moving it, has a pretty blue night light, and best of all...it rarely needs to be cleaned. I've had my first for about 6 months and still hasn't needed a cleaning. FYI.. Keep in mind, when using essential oils in the tray, A LOT of those oils are toxic to most pets. Do your research..
