Air-O-Swiss U650 Ultrasonic Humidifier Customer Q & A

Air-O-Swiss U650 Ultrasonic Humidifier Product Details
Q1: I just bought the U650 and it came with a hydro cell in a bag inside the box, yet nowhere in the manual does it even mention a hydro cell! Where is it supposed to go and what does it do? Also, does not mention automatic shut off. What if the unit runs out of water when I am not home to refill? THX

A: Air-O-Swiss is transitioning all their humidifiers to the Hydro Cell in place of the Hydro Stick which was in place of the Ionic Stick. So there's some disconnect with some models having it, some not and the language in the manuals. The Hydro Cell is pretty simple in terms of use though. When you remove the screw-on lid for the water tank, just it inside before you fill with water. That's it. It's a small disc that contains carbon similar to a Brita or Pur water filter to remove minerals, chemicals and other impurities in the water. You replace it after about 1-2 months worth of use. And, when the unit runs out of water, it will simply shut itself off. I believe the U650 has a small indicator light on the front display that will light up, but the unit itself will turn off automatically.
