I use that little filter inside my small Box.

It works decent. not too great though I'd say it cuts off half the smell. 20bucks can't go wrong.

If you wanna see a pict Look in the INdore Growing section... Look for a thread called "EXtracting Pollin From a Male"

If you look at the picts I posted today youll see the filter behind the fmale plant..
