So I think the exhaust fan is more important than the carbon filter and I want to suggest the ac infinity cloud line t6. Its fully programmable. While they make a 4inch and an 8 inch, I would go with the 6inch for your tent. You will always be able to dial it down if it's too high. For the filter I suggest a 6in from terrabloom, that handles 400cfm. These will pair nicely. I don't know where they are made but a little research on amazon can't hurt. (These are both on my personal wishlist). Hope that helps. Hope your shoulder heals well.
