Question about ecofort ecoQ DryAir 20L Energy Saver

The appliance is not noisy. You leave it running (24/24) in humidity control mode and it starts and stops automatically.

In the same room it's too loud for me, behind a closed door or two it would probably be okay.

For me, the unit is not too loud, rather surprisingly quiet for its performance. I practically don't hear it, especially when there is still some activity in the room, and otherwise I only notice a slight, non-disturbing compressor noise and a fine hiss. The noise is far from the noise of a monoblock air conditioner.
