Is it safe to drink out of a 15 year old water filter?

Is it safe to drink water filtered by a 15 year old Pur hand-pump camping filter that I haven't used in a decade? I rarely used it even back when I originally got it. I'm going camping tomorrow and just wondering if there's any reason to believe that chemicals in an old water filter may somehow become unsafe or ineffective over time.
