Addendum - experiences after frequent operation
Every now and then I have found WHILE operation vibration noise. The causes, however, are easy to fix.
1. The handle can easily vibrate and rattle in the folded position during operation.
Remedy: flaps in operating the handle just to the top.
2. The removable mesh filter to vibrate. The grid is to use a little fiddly.
Remedy: enfach the filter insert with 4 adhesive strips on the corners of the filter mesh stick (not visible externally). The corners are then performed well on clipping the filter grid, they can no longer stick out and have a slight bias.
The insertion of the mesh is then a breeze and the filter can no longer rattle.
I am still enthusiastic about the device - the dehumidification performance is excellent.
