Air-O-Swiss Hydro™ Stick

Air-O-Swiss Hydro™ Stick


The patented Air-O-Swiss 7017 Hydro™ Stick is the cornerstone behind the germ protection system of all Air-O-Swiss Humidifiers, including the Air-O-Swiss 7135 Ultrasonic Digital Humidifier sold by Allergy Control Products. Using the antibacterial effect of silver, the Hydro Stick prevents microbial growth from occurring in the humidifier’s water chamber base.

As silver ions are released into the water, the Hydro Stick discharges more from its internal storage, so you can always be assured your humidifier’s water is fresh and purified of contaminants.
