I have been getting confused while looking through inline fans on what filter I need. I planned on getting this one because I have a small grow going, only 2 plants in a 2'H x 1' D x 1'.5" w trunk.

It's a 180 cfm output fan. I'm taking a guess but since it's 180 cfm does that mean I'd need a filter rated over 180 cfm such as this one?

I had also had my eye on a 95 cfm fan, but I am unsure what type of filter to buy. I'd appreciate any help.

you want the fan to have a slightly lower cfm than the filter. if you have a fan with a higher cfm the air would pass through the filter too quickly and the smell might still get through.
