Sleek Humidifier

This humidifier has a sleek design and is very easy to use straight out of the box. You can fill the reservoir with water from the top, which is very convenient, but we noticed that limescale builds up very easily on the filter inside. We weren't aware that it's better to use distilled water, as it doesn't say that anywhere. The filter is also quite pricy at $39 so having to replace it often isn't a great feature.
