Water quality maintenance
The Hydro Cell keeps humidifiers operating at their highest
level between recommended cleanings. Good for approxi-
mately one to two months, depending on the water quality,
the Hydro Cell ensures the humidifier's functionality while
providing fresh humidification performance. It starts to
work as soon as it comes in to contact with water, even
if the unit is turned off. The Hydro Cell should be changed
every one to two months*. Look at picture 19/20 for the po-
sition of the Hydro Cell in the water tank of the unit. Switch
off the unit first. Contact your local retailer or check our
website www.airoswiss.net for reorder information.
* Depending on the water quality.
