Holmes 1-Gallon Top-Fill Ultrasonic Cool-Mist Humidifier
This humidifier is really convenient with a filter-less operation, there’s nothing more to buy and since the humidifier fills conveniently from the top, you don't have to carry any water tanks. The viewing window lets you know how much is in the tank.
It offers two mist settings and is pretty much runs silent. It’s ideal for any room in your home or office but I have it right by the head of my bed, so that it mists over my face. This really helps during with dry climate.
It does take up some counter space, but at least it runs vertically instead of horizontally. The capacity is 1 gallon of water and can run for up to 60 hours.
