The Oskar Big Evaporative Humidifier has been engineered to provide strong, virtually silent performance, without leaving behind any ‘white dust’ from minerals in tap water as is common with ultrasonic humidifiers. Oskar Big doesn’t have a traditional water tank, but rather is filled using a jug, making refilling easy. Oskar is also the easiest style of humidifier to maintain and clean and also includes a Water Cube to keep the water fresh between cleanings.
I had high hopes for this humidifier. It's very attractive and silent. However, it has stopped working after 3 months of use! It's awkward to fill. The opening is very small, so I just take the whole top off to fill it. I'm hoping the warranty is still good! I have never paid so much for a humidifier and I have never had one work for such a short period of time!
