Is my JET AFS Damaged?

After waiting 2 weeks for my AFS-1000B from Amazon, using free delivery, I think it showed up damaged. When I look at the end with the filter, it looks like the center is squished a bit. It I measure the sides they measure 12: but the center measures just under 11 1/2". It almost as if the center was squeezed together. When I removed the outer filter and rotated it around, it didn't easily fit back in. It looks like it was crushed a bit on one side (not much though) so that side had a form fit.
I turned the unit on last night and it seems to work just fine. So my question is if other people have had a problem with the center being crushed. Is this a common issues, or just mine? Have people sent them back or just dealt with it?
I tried (gently) to take out the inner filter but it wasn't moving. It looks like the metal frame was bent a little bit. I don't know how easily the inner filter comes out so I didn't want to force it and break a seal or glue. So any info on that would be helpful as well.
Thanks!

Mine is about 11-3/4" in the center, hanging from the ceiling. Keep in mind it hangs from the top so gravity is going to pull it down. I suspect they build in a little bend to it, rather than make it stronger, so when it hangs it doesn't end up wider in the middle.
