How Odoryxell Works

Seven atmosphere light colors help create a cozy room ambiance. Touch humidity control and keyboard-type operation make the device clear and convenient to use. Water-shortage power-off protection and noise level below 36 dB support safe home operation. Portable design and USB power make the humidifier practical for tabletop or shelf placement.
