Why? These were originally sold as "lifetime" units - the one I removed had no physical defects or faults, other than the seals on the elements were failing.
While I can respect that an average unit only lasts for approximately 15 years, I can also imagine that top of the line products might actually have an indefinite lifespan (pending maintenance, proper care, etc). They are located in a sheltered alcove under a stairway, and it is a dry basement.
It seems to me your reply is simplistic and doesn't respect the facts of the situation.
