I think we have one of those... should i get an extractor fan for it?
Yeah thats right..I had a damp expert come in to identify the problem, and this was his solution.
If the air-brick is in the bedroom them a fan for it wouldn't be terribly practical..it'll be devilishly noisy for a start which means you're unlikely to use it enough to make a difference.
In my case I had two installed at the top of the exterior walls, but of course your situation may be different.
Although a dehumdifier will do the trick (it worked for me), it simply doesn't cure the problem, and having a noisy big box that sucks electricity is a poor temporary fix.
It won't cost anything for an expert to give a quote (get a couple of them to be sure) and at least you'll know what the problem is.
