Cheers dude's now for my next set of question...

A smell scrubber, this is an important item for me as my other half would blow a fuse if she could smell it, i would if i could make it myself, i know it requires carbon but i wouldn't know what carbon to use, the only carbon filter i have used was in my fish tank filter, is it the same stuff???

Now for air circilation, was thinking of using two 80mm pc for fans sucking air in and one 80mm pc fan for blowing out, i assume to the smell scrubber?
Any thoughts ?
