Recently ordered a couple of these and suspected they were pretty old. Posted about it here:

I suspect they were made in 2011 which is old enough to make me question using them so I decided to cut one open. Looks like a nice filter the media was evenly spaced and the anti-drainback valve was soft and pliable. The media also wasn't brittle or anything. Think I should be fine to run the remaining one.
