Hi all, forgive me but im new to this forum thing so if iv put this in the wrong place im sorry. Im looking for peoples opinions on the Nuair Flatmaster. Im in a council property and have really bad problems with mould in both bedrooms. They have cleared some rubble from the cavity and put new cavity wall insulation in. Iv also used the mould paint twice in both rooms but its still coming back. They have now said they would fit a Flatmaster if i want, the only thing is the man who suggested this has said that people turn them off in winter because they blow out cold air. So my problem is, the mould is worse in the winter and if i have to turn it off is there much point to it. Is it true that they blow cold? and do they really work?
