I have just one bedroom out of a few that has a humidity problem.
Two of the walls are external and are always in a constant shade.
Very damp, and wet. <- the wall in the fitted wardrobe.
Instead of jumping in at the deep end, I purchased a humidity monitor.
It was sitting in the 70's in the day, and when I woke this morning it was 86!!! haha (I must be a steamy sleeper)
So, time to get a dehumidifier.
From what I have read, I would prefer a desiccant? one as the room is pretty cold.
So, recommendations please??
