Should I buy a 6" or 8" carbon scrubber?

I grow 2-3 plants at a time in a 2x4 tent. I need to upgrade to a better carbon filter because my 4" filter is struggling with the stank. Would a bigger scrubber filter the air better? The price difference is only about 20 dollars between a 6" and 8" fan. I am thinking the 8 inch would be better, as I could slow it down to scrub the air better. I want to make sure I can grow some extremely funky strains, and not worry about it.

What size and type of fan are you using and what is the length.and diameter of your carbon filter?

This is the one I have:

And this is the one I'm looking at:

An 8" filter will just put more strain on the 4" fan.Notice how the filter has a recommended minimum.and maximum airflow rating?!

I am not going to use a 4" fan with an 8 inch filter. I am deciding whether to buy a 6" fan or an 8" fan. My area will be a small tent 2x4. The smaller 6" fan is about 370 cfm while the 8" is like 750 cfm.

Bigger filter equals LESS restrictive.

Always go big and you can use a variac speed control to tune your cfm to your needs. An 8" at 70% speed will be less noisy than a 6" at full.

Snap thanks for the advice. I did notice the 8 inch has double the cfm. Id rather have too much filter, than not enough!
