Cool Mist Humidifier for Bedroom, Ultrasonic Humidifier for Home and Dry Air
-
Quiet enough for a light sleeper: this quiet humidifier runs below 24dB so it never disturbs your rest
-

-
Good for people and plants: steady output makes it a dependable humidifier for plants as much as for your bedroom
-
Set the mood too: three mist levels and 7 night-light colors match any room
-
Safe to leave running: it shuts itself off automatically when the water runs low
Dry air leaves your skin tight and your throat scratchy by morning. This cool mist humidifier fixes that by turning water into a fine mist that keeps the room comfortable all night, so you wake up breathing easier instead of stuffy. It runs whisper-quiet below 24dB and shuts itself off automatically if the water runs low, so it is safe to leave going while you sleep.

Inside, ultrasonic vibrations turn water from the 84.5 fl oz (2.5L) tank into a cool, fine mist instead of heating it, so this works as a genuine humidifier for dry air without warming up the room. Add a few drops of oil to the tank and it pulls double duty as an essential oil humidifier, while the three mist levels and soft night-light make it just as much a sleep humidifier for a bedroom as it is a dry skin humidifier for tight, flaky winter skin. Set it up as a winter humidifier in a nursery and it works gently enough to double as a nursery humidifier — or keep it on your own desk as a personal humidifier for allergies and dry air at work.
