Sharper Image Ultrasonic UV


L ikely the most eye-catching trait it flaunts is the fact that it allows selecting between warm and cool mist output. As the Sharper Image UV humidifier allows you to choose what type of mist it releases, it comes in handy for households with small children as warm steam can pose a danger for them. Thus, with your ability to switch between mist type settings with ease, selecting cool or warm depending on the room you use it in at that moment, you ensure proper humidity levels are maintained without putting anyone’s safety in peril.


It features manual controls that grant ease of adjustment, so you can set the steam output and the temperature as you see fit. Keep in mind that if you adjust it to produce warm mist, the water reservoir will empty faster and it will shut off automatically when this happens. That is when the LED indicator light turns on to let you know that you need to refill the humidifier. Although it can meet anyone’s needs, it does not integrate an adjustable nozzle. Instead, it features vents that are located on the top side and that can be adjusted to release steam forward or straight up.
