Review on BONECO Digital Humidifier S250 Cleaning by Keebs Alter

It does its job - it's not so noticeable when it's on, but it's very noticeable when it's off for a while: it becomes much harder to breathe in a closed, dry room. An important point - I live in a region where it is still necessary to look for "hard" water, and there is no problem of scale formation. And I have not tried to fill it with unfiltered water (and I am not going to). Therefore, care, cleaning and consumables are required minimally.
