Amazing cool mist humidifier. Can run for hours on a medium mist. I love the night light, it looks like an aquarium with the bubbles going up from the mist. Also impressed with the silver coated plastic panels, I’ve had no mould issues at all and there have been a few nights when I didn’t use the humidifier and it sat with water in it. I am very impressed with this unit. I want to purchase one for my parents.
