Review on Humidifier Stadler Form F-008EH, white by Celina Pietrzak ᠌

I have 3 Stadler form humidifiers. This one is the most beautiful. But he let me down. In the second week of operation, the coating of the heating element (bowl) began to fall off a little at the edges. And the corrosion began. Inside the humidifier, everything began to be covered with a black coating. And clean, don't clean, it only gets worse. There is no scale, but corrosion continues. And it's scary to clean. Because all descalers are acidic. And the bowl seems to be made of some kind of silumin, which is not friendly with acids. As a result, through. A little through, but already unusable, of course, because under the bowl of an electrician. Of course, I can understand a lot . but through and through in one season? it's something. Read reviews. A similar problem occurs. And there is no solution. Replace heating element. And everything repeats. Apparently there is a marriage of coverage.
