The Oskar has a unique technology here. Here neither water current eating atomized heated even by ultrasound but via a clever system to damp filtering past and, so power efficient and free of germs in the air.
The whole thing does not just look good but also works really well. In our truly great kitchen we had without the Oskar rarely more than 42% relative humidity, which I often suffered from bronchial complaints. With Oskar, we have now more than 50% humidity which regularly leads to a much better living environment.
Need to keep these humidity be almost constantly in operation but the Oscar. At the highest level (supposedly controlled by Hygroskop) he shall hold 55% humidity. If this value is reached / exceeded, the Oskar supposed off what he has but has never done. However, since it only requires 8 watts in the lowest ventilation level, bothers me not really, because he's always pleasantly quiet, actually almost inaudible!
I also think that you can dim the blue LED's and even off completely ... would disrupt the evening in the dark living room after all.
CONCLUSION: The Oskar is so simple and elegant, designed to that it actually fits into any home decor. In addition, it is easy to operate and performs its service reliably. Even in larger rooms it is able to increase the relative humidity up to 10% ... endurance required. He has certainly done a great service to our living environment, so clear recommendation!
