Have used one to dry out a wall which had water damage after a leaking hot water tank. Had it on continuously for several weeks and pleased to see that it,s done the job. For its size it is amazing. I now have several around the house where dampness may occur during the winter months. Especially effective for clearing bedroom window of condensation.
bought this dehumidifier as i have an identical one in use,
this one is used to lower humidity in another room to save on the cost of heating
as i do not need to open windows in the winter to keep humidity down.
