In the living room. Smells of damp/general mustyness.
It comes intermittently and is quite strong. I've checked everywhere no signs of damp at all. Air fresher lasts about 10 mins before it's back. It comes in a big waft then goes then comes back?!
I've no idea what it could be... going to wash carpets tomorrow and see of that helps but any ideas?! It's driving me mad...
