In figure?
He lowered the humidity of 70-80% to 40-50% on average, in a room of 15 square meters, turning 2 days / weeks approximately.
It may come down to 30% if I let it run too long. (40-60% is the EU standard recommended for a healthy home)
I wash the filter under the water every two / three weeks or I've noticed that he tended to be much less effective, it sucks as much moisture as the dust particles in the air.
It works great, day or loose it again I direct.
