    I read that carbon filters on inline fans reduce the cfm.My question is how much does the filter reduce the cfm's on a inline fan? So for instance this 6" fan/filter combo on ebay pulls 440 cfm. But around what would the actual cfm be with the filter on? TY

    Good question but without the equipment to test it I doubt anyone here would be able to give you an exact answer in terms of CFM. That size of fan and filter would do a good size room for odor controll.
     
  3. if its htgsupplys stuff it drastically brings the cfm down when you add the carbon filter.

    but it keeps my thousand watt cool and smell proof.
