just a bit of a boring thread really, i purchased an extraction fan a few weeks ago, as i was starting to suffer with coughing, i put this down to me breathing in the particles from filing,(tho it wasnt much), anyhow, i got this extraction fan that was advertised in Geekbay, and all i can say is "its brill", and for £35 you cant go wrong, it is well worth the money, the reduction in dust particles is amazing, there aint no more particle making there way upwards towards my overhead lamp, the client isnt covered in this awful dust (neither am i) its great, so for anyone thinking about getting one of these, all i can say is GET ONE, you wont be sorry, even my clients have noticed a difference in the reduction of dust
