With all dehumidifiers I had the opportunity to test, this one is top notch! Manufacturing more robust than most other products on the market and much greater volume that will not be obliged to empty the bin every two weeks ... Effective for large rooms such as attics and basements as well as in average volumes such as bedrooms and living rooms, however inadvisable to Dufait in small spaces of its size and its design that does not make something very discreet ... The only star I removed it is due to lack of protection in the handling of the dehumidification unit which should be more convenient. It is ultimately the best product of its kind, you can buy eyes closed.
