CLEAN AIR OPTIMA WF-01W Water filter humidifier

The water filter W-01W reduces limescale in the water and the unwanted emission of limescale particles into the room. Effective for one to three months, depending on water hardness. Hard tap water accelerates the saturation of the granules faster so the water filter W-01W needs to be replaced sooner.

Suitable for humidifiers:
CA-606W
CA-607W
