Thanks to its outstanding design and uncomplicated handling, the W220 air washer is not only an eye-catcher but also an easy-to-clean enrichment for your rooms. You can run the appliance effortlessly for up to three days and achieve ideal humidity in your home. You can fill the appliance with water in place from the top without having to disassemble the unit. The knob allows you to select between two performance levels: day or night mode. A red LED lets you know that water needs to be refilled. In addition to making the unit convenient to operate, the designers also thought about making it easy to clean – most of the parts can simply be put in the dishwasher or washing machine, saving you from spending time scrubbing by hand.
