In itself a beautiful thing, a lot of potential I thought. First few days the humidity went from 30% to 50%. Top. He couldn't go any higher than that, not even at full power.
After a day or so, the humidity slowly dropped again, to about 35%. It turned out that the glue used for the label on the filter (you can't remove it) pulls through the filter. The top 4 centimeters have completely hardened and are no longer able to absorb moisture. Since air also chooses the path of least resistance, this meant that the device was almost useless.
Had contact with coolblue and helped very well (as always, chapeau). Incidentally, in my opinion, coolblue is one of the best in this area, customer-friendliness knows no boundaries.
Well, I got another one. Full of good must be filled again and put into use. Unfortunately, after two days, the filters begin to turn yellow and harden. Same story. Put a hygrometer on the oskar: first day an outflow of 65%, now two days later only 50%. (both with a full tank).
Finally, I find refilling very difficult if the thing is a bit higher through the cover. But that depends on where you place it.
Unfortunately, looking for something else.
