I bought this unit due to standing water when drying clothes in winter a long time ago. It is definitely not suitable for bedrooms and visually no looker. At high relative humidities (above 65%) and high temperatures (above 20 ° C), the device works well constructional reasons, for much lower humidities and temperatures lacks the force. So far, no wear is visible after 2 years of use, but was treated very carefully. I would buy it again.
