We have a small damp problem and have borrowed a dehum, it's been on all day today and collected lots of water, quite shocking really - but have just noticed that washing that is currently taking around 4 days to dry out on the airer is almost dry after just being put on last night! Am amazed! Seriously considering buying one of my own now just for this 
Is this a universally known thing or have I stumbled upon something revolutionary?
[imagines making a million out of this somehow...]
And can anyone recommend what to look for in buying a decent dehum for a one bedroomed flat - budget - as little as possible!
This thread is a bit old now, but if you've landed here looking for recommendations, we've recently updated our best dehumidifiers round-up, full of products tried, tested and recommended by Mumsnet users.
