has anyone designed a carbon filter powerd by a computer fan ? or mabie 2 computer fans 
i was going to make one but dont know if a computer fan would be enough power to get the air past the filter and out the floor .. but noise is a problem for me 
im hoping that will be enough to vent a closet gro with a few plants 
every carbon filter i see seems to be attached to big venting fans
