Will not buy again
It puts out a fair amount but it will say it needs to be refilled when its almost full. The tank cap is cracked also...

Exellent for the bedroom
Finally a unit that holds more water than specified. Easy to operate and to refill. Not much cleaning needed except the wicker filter needs some rinsing or to be replaced. This unit helps warm up the room and moistens the air just right. It lasts about 2 hights or 16 hours or less.

Optimus is an optimal humidifier.
I like it. It's quiet and the adjustable output of heated water is enough to make a difference. When it's working, I can set the thermostat down and it feels about ten degrees warmer because of the increased humidity. With the winter weather we have been having, my sinuses were inflamed and suffering, making me more apt to get a virus. So the humidifier is for health reasons and comfort. I usually only fill it up to two gallons so it's easier to lift. It works better than the kind that cause a lot of calcium deposits that are essentially steamers and you can hear the boiling water. The filter lessens deposits and protects the heating element and makes it run more quietly. Still important to read the instruction booklet and clean and do proper maintenance on it to extend its life.
