When it gets cold outside, we tend to turn on the heating in our apartments: the relative air humidity drops. The dryness has adverse effects on us, the furniture, plants and even objects. Fred humidifies the air, so we can feel comfortable again.
Fred is clean - because it is free from minerals and bacteria. Fred also has an automatic cut-off.
Because of the conductibility, Fred shouldn't be filled with distilled water, but with normal tap water.
