almost perfect humidifier, almost. puts out about 5gal a day on high, description is misleading it was advertised at 800ml/h and 560ml/h. good for 550sqft realistically. wish it had an extension spout to mist higher up in the room. overall great design and humidifier, i bought a second one. mounted on a 27 gallon tote reservoir i use for ro water storage and it runs 24/7. also has cool purple uv light inside.
