Published Aug 29, 2024 at 03:07 pm (Order date: Aug 17, 2024)I installed it a week ago inside a cave adjacent to a completely renovated dammuso. I do not have enough evidence yet to confirm its validity, at the moment I am using it H24 with continuous discharge and it works without interruption. I used it with the collection tray the first few days and was emptying the cassette twice a day. I would say that it pulls water. (Translated review)

Published Sep 02, 2023 at 02:27 pm (Order date: Aug 23, 2023)The product does well what it was designed to do: dehumidify. The only point I hadn't considered, but it doesn't create any particular problems, is that it raises the temperature of the room in which it is used by about 1-2°C... I use it for three/four hours in a row and the studio goes from 24°C to 25°C and sometimes 26°C, maybe I'll appreciate this in the colder period... (Translated review)
