The Macally HMDUSB Multifunction Ultrasonic
Cool Mist Humidifier provides quick relief from dry
air making life pleasant for those with colds,
allergies and dry skin. The space-saving design,
with an easy-to-fill 240mL tank and USB
attachments (LED night light and Fan) makes it
ideal for use at work on your desk, or at home on
your nightstand. It disperses a fine mist into the air,
and is ultra-quiet making it ideal to have on while
you sleep. The humidifier is also equipped “Anti-Dry
technology” to prevent dry burning (turns off
automatically when the water level is low) and an
indicator light to let you know when it's time to refill
the water tank.
