The only downside I’m aware of with those filters- besides you can’t get parts anymore- is they don’t like chlorine. Bleach sterilizing your water system required bypassing that unit. My previous Wanderlodge had one (different brand) and it was also a 1996.

While a replacement filter was never found for ours, I figured I had another 10 years of usage before it really needed attention 70,000 gal divided by 120 gal tank is 583 full fills. My coach was getting about 10 fills per year on average.
