cleans the air, dehumidified very effectively; tested uninsulated house 90m2, with cold and damp walls !!! aesthetic, he moves easily from room to room, in 2 hours time the amount of water discharged is impressive, drywall, bedding too !!! more sensation of being frozen to the bone !!! for absences of more than 24 hours by the direct evacuation pipe is pratique.sa consumption 330W max is not currently idéal.n'ayant not afford for good insulation; it allows a better everyday comfort. the manufacturer seems very professional, which reassures me if problem.
