CLEAN AIR OPTIMA WF W-01B Water filter humidifier

The water filter W-01B 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-01B needs to be replaced sooner.

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