I live in Poland, and during the heating season the air here gets extremely dry. I decided to buy the Stadler Form Oscar humidifier and I’m 100/10 satisfied. It works very quietly, has an automatic mode, can maintain a set humidity level and then turn itself off. There are 5 power levels and a soft backlight that can be made brighter, dimmed, or turned off completely. It runs 24/7 in my bedroom and doesn’t disturb my sleep at all, even though it stands right next to the bed. It also has a compartment for aroma oils, a silver ion filter, and comes with two large replacement filters that last about two months. Highly recommend it. BTW - it’s very compact for its power.
