How would this carbon filter hold up

Cab Dimensions: 4'L x 2'W x 4'H

Lighting: 400w HPS w/ supplementary CFLs

8" 500 cfm intake fan, tower fan, 6" Inline ~400cfm exhaust fan

Strains: Aurora Indica, Northern Lights

I'm planning to either sog 7 plants or scrog 2 plants.

How effectively will this carbon filter suppress the odor?
The air in the room will be filtered in plenty of time but just want some input on this carbon filter.

Thanks

Carbon filter looks legit to me, says it has a 5 year warranty on it too. Main concern to look for is the quality of the fan, the carbon filter just houses the activated carbon. $140 is a pretty reasonable price for one too. Should do the job.

I would try to keep all your ducting the same size though, JMO.
