I live in an old house, especially without ventilation and when it rains and it is not the heating season, humidity rises to 65%. I first bought a Zibro D512 extremely low-noise for my kitchen and dining room where humidity is most present as soon as there was daily activities, but I use it now in an underground chamber or dryer because its capacity is a little small for the kitchen volume (75 m³).
So I bought a second, more powerful model, the D516, volume up to 105 m³. This device is remarkably powerful and quiet! I have never experienced as quiet as dehumidifiers Zibro models. There are no more noisy than some fans blowing or some heaters.
In 6 hours it was recovered up to 2.5 liters of water. I can make it work without noise disturbance and low fan speed position, it is hardly louder than the fridge!
Its use is easy and very convenient because it has a timer (as the D512) that allows automatically stop or initiate a "start delayed". The performance of these devices have nothing to do with chemical absorbers, totally ineffective home.
I am very satisfied with this product.
