Excellent warm mist humidifier — simple, effective

Excellent warm mist humidifier — simple, effective, and reliable This Honeywell 1.5-gallon warm mist humidifier works exactly as advertised. It puts out a steady, comfortable warm mist and easily handles a large room. On lower settings it lasts close to a full day before needing a refill, and it automatically shuts off when the tank is empty, which is a great safety feature. I also appreciate the essential oil aroma tray — it adds a light, pleasant scent without mixing oils into the water. Very easy to use, quiet, and solid build quality. Perfect for dry winter air and overnight use. Would definitely buy again.

Quite and Efficient

I purchased this humidifier because of static. It's very quite. Puts out a good amount of steam. My hair no longer clings to my face in the morning when I brush it. Being winter time, it also warms up the room a bit. It is very easy to clean and remove parts. I have extremely hard water, which it built up on the inside of pump area, vinegar dissolves it fast. Definitely a good deal.

Please keep selling this make and model!!!

This particular make and model of 1.5 gallon warm mist is the best we've owned in recent years. The newer version, quite frankly stinks. The controls on this one are reliable. The electronic controls on the newer one work sporadically and ultimately break quickly.
