Odor and extraction!

Hi guys, I have a tent which is 1,20mX1,20mX2m
And now I want to set up a odor filter and extraction system. I want to know which odor filter do I need and which extractor do I need. If you could answer me in the metric system it would be great! (Cubic meters)
Thanks!

No idea, if they use metric it must be in non-english speaking countries.

You should be more than covered by any 6"

Add a speed controller if it doesn't come with one.

You want to be able to clear your cubic volume at least once every 2 minutes. You also want to be able to set it where it needs to be not excessively high speed.

thanks! I was wondering about the intake too, what intake fan would work for the space? thanks
