Customer Reviews for Optimus 1.5 gal. Cool Mist Ultrasonic Humidifier

The unit seems to work very well as far as a humidifier so the overall quality seems very good to excellent. My only minor complaint is that the bottom section gets filled with water so in order to refill each night, one has to unplug the unit and take the whole unit to a sink to first empty the bottom section, then fill the reservoir. Humidifiers I have owned in the past were much easier/simpler to fill.

This thing barely works. I've only had it for 2 weeks. I have to nudge it to get it to run at ten minute intervals. I'm not happy. This item does not meet my expectations.

The product performs exactly as described. The mist is fine enough to prevent the carpet or tabletop from getting wet and the amount of moisture produced prevented static electricity in a medium sized room.

1st ever my humidifier! i can smell something like plastic or chemical from water vapor which is not good. night lamp switch is hard to push so every time you turn on or off you have to hold unit with other hand. Vapor is good and with force. but you can not have it on full flow as you will have water wet around your unit as force is not that much that can flow vapor away when it is in full flow. otherwise it is good if you use 75% of regulator. Price is Okay. Noise is not too much. but you can hear even it is 10 feet away from you at night. but it is not bothering me. I will buy another one for my main room but i will try something else just to try out. I AM HAPPY With This UNIT. BUT, I am expecting that if cleaning instruction was included. i dont know how to clean as water stays in all time and it is not good if you dont clean a week.
