Carbon filter cfm

  1. If carbon filter says 440 cfm and I have 400 cfm fan is it so post to be less or more? Im debating to get 4 in or 6 in carbon filter. The 4 in carbon filter is 190 cfm. Which would work best or does it matter? I have 4x4x6.5 ft tent
    I would rather get 4 in carbon filter and get the 4 in to 6 in converter so I could fit with the duct and fan I already have. It would be cheaper than the 6 in carbon filter by itself
     
  2. Get the larger filter. It will last longer, do a better job and allow more unrestricted air flow from your fan.

    Generally value for money is better with larger filters.
