Quiet unit / visually beautiful

Our first device of this type, we had bought at a hardware store.
Crucially, the device is fairly quiet. (According to our subjective feeling; we do not use the device but in a living room). We once had a portable air conditioner - and that was against murderous loud)
The device looks visually good.

After a year we have bought 2 more units at a lower power class because of the good experiences through Amazon. (OK for us, but the performance difference to the higher performance classes is noticeably --- the price but it is also)

We use the device for dehumidifying the basement and turn the power on only as needed.
(Every 1-3 weeks for 3 to 4 h --- depending on the season)
Especially the spring is critical if the basement is cold and moist warm air flowing into the basement when opening the door.
If the air then cools, it can be a moisture problem quickly.
In the basement door is closed, the devices in the house are barely audible.

We had previously used dry pellets - but was too troublesome in the long run.
... And I was afraid of spilling the salt solution ...
