I dropped a piece into the water container and few days later I found the humidifier was covered by a layer of white particles, I am not sure if the appearance of the white particles were normal or not. I stopped using it anyway.
This Optimus U-31001 ultrasonic humidifier puts out up to 1.5 gallons in 18 hours, ensuring your living area stays comfortable. The adjustable mist control allows you to set an ideal moisture level.
This is the second humidifier I have (the other one was noisy, expensive and only worked for couple months). This little thing is rather quiet only sometimes you can hear the water running. Considering about the price, this is something good.
