I got this Honeywell Cool Mist Humidifier to add moisture in the air, and make any room more comfortable. Bonuses are that it not only makes for better sleep because of improved breathing, but also helps protect my wood floors and furniture. I like it's simple and practical design. Its lightweight so it's not a problem to move from room to room. I like that it doesn't need filters to operate it, and the tank is easy to clean. It has an essential oil tray with an essential oil pad built into the base. The only assembly needed is putting a float paddle in place as directed in its manual, and connecting its adapter cord. It has a big water tank and a turn dial that allows you to choose how much cool mist is released into the air. It comes with a cleaning brush and you can turn the two nozzles in the top, in the direction you want the mist to flow. It is also quiet which is great. I like it!
