On both I can blow into from both sides and air pass through, are both damaged?

Not a direct answer but one of the two I received failed after a few weeks; upon removal I was able to pass air thru both sides. I did not test the new one (should have), but it seems to be working fine.

vendor higher CC number means more resistance or less resistance?

Higher number means less flow resistance (higher waste water flow to the drain).
