User Manual HoMedics UHE-CMTF91 Ultrasonic Humidifier for Large Room, TotalComfort Ultrasonic Deluxe Humidifier

Humidifiers are not required to be BPA free and we do not make the claim that it is.

Yes, you can. Press the night-light button once to turn on the night-light. The light at the bottom of the humidifier will turn on. Press the button a second time to leave the night-light on, but turn off display panel. Press the button a third time to turn off the night-light and display panel so no lights are illuminated. Press the night-light button a fourth time to turn the display lights on.

We would recommend placing this on a water proof surface.

The UHE-CMTF91 humidifier does not have UV-C.

That depends on the settings used and the existing humidity in the room the product is used in.

This product has a humidistat.
The default humidistat setting is CO (continuous on). The programmable humidistat can be set in 5% increments, from 35% to 55% humidity.
To program the humidity level, press the programmable humidistat button. The humidity level will increase by 5% each time the button is pressed and will be displayed on screen. Press the humidistat button repeatedly until the desired setting is reached. The display will show the set humidity level.
