It's been awhile since I posted on this forum but it has to do with a Carbon Filter so I thought I'd use the same post. I just got my carbon filter in the mail today... I ordered it from ebay.

IT'S FREAKING HUGE! I'm 6'1 and it comes up to my waist almost.
I ordered a 8" carbon filter but did not think it'd be this big.

Never had a C.F. b4 so I don't know if this is normal or if some Ebay guy just got one over on me?
DeeMar10 Reviewed by DeeMar10 on . Carbon Filter: How many CFM's ? I'm looking for a carbon filter for my 8" inline exhaust fan which put's out 675 CFM's but I'm not sure what kind of carbon filter rating I should be looking at? I found some priced at $150 that says 240 CFM's Then another set $200 for 750 CFM's For $50.00 I'm sure the 750 CFM's is probably the way to go ? But why? Any advice would be great. Rating: 5
