Review on Horticat U80 Ultrasonic Commercial Humidifier by Tammy Jackson

Well, I'll reiterate many of the points made by the previous reviewers. The device humidifies reliably. The hygrostat is not very accurate. YOU MUST USE REVERSE OSMOSIS WATER. Any other option will leave a white, chalky residue all over your room after a few days. After switching to a reverse osmosis source, this problem disappeared. I've only been using the device for a few weeks but so far so good!
