Q: Do the u3 and u4 use the same?

The u4 is longer than the u3 cartridge , you could use a u3 in a u4 but it would just be a bit short in the cage that holds it

Q: Do the u3 and u4 use the same?

No they are different sizes, hope that answers your question

Q: how many poly/carbon cartridges in a box?

Hi there are two carbon cartridges in the box. I find them a great asset to my tank and keep it clean.
