We bought for a living room of about 40 m² with an open staircase and I am thrilled. Already after the first hour there was a noticeable difference - it is easier to breathe, it is not so cold at the same temperature (21.5 °C), static electricity has disappeared and we can breathe better than with the original 30% humidity. The device is very quiet, the design is nice (no plastic monster) and the warm steam helps to get the humidity to the ideal value of around 50-55% faster (for us it took from 30% to 50% in about 1 hour). The controls are simple and the performance is sufficient for larger spaces. ⚠️ Recommendation: Be sure to buy an external humidity meter. The one built into the device logically shows higher values because it measures the air directly around the humidifier. An external sensor located a few metres away shows you the real humidity in the room and helps you set the ideal maintenance regime.

Excellent humidifier. We already have two at home. I had the first one from Concept and it doesn't compare to this one. And it's actually the same price. This one is still silent, you can slowly set everything you want in the app. At first I thought, I don't need a wetting machine with wifi control. Wrong. It's totally awesome. We have a humidity meter in the room and it matches what the instrument is measuring. Although more parts have to be disassembled for washing, it is still relatively convenient. Best buy in a while.

This way the purchase paid off, we finally sleep better and I hope it lasts: )
Humidity sensor
The quality of the steam, there is no "wetness" around it and the distrubuce breaks through perfectly
The ability to connect to Alexa and automate your switching: )
Possibility to connect an external sensor to refine the measurement
Tank size
The sound is quite soothing at night and does not disturb
Hot and cold steam option
Worse cleaning, the folds want to scrub with a brush but it's not impossible, just more time consuming

Although the volume of the water tank is 4.5 litres, the entire contents of a 5 litre pack of distilled water sold here on Alza https://www.alza.cz/maxi/zenit-destilovana-voda-5-l-d9794198 can be poured into it without the slightest problem. htm.
when used according to the instructions and with distilled water, the product, considering the price of less than 2 and a half thousand, is flawless
the humidity meter integrated in the product understandably shows higher values initially, but after proper dispersion of the humidity in the room it differs from other humidity meters in the room by 1-2% at most
for someone used to the noise of computers or fans, the product is extremely quiet
Warm steam warms the air slightly
aromatherapy works great, although I feel like it runs out before the water tank is full
does not remember lighting settings after switching off/on
