Do you see a longer or shorter filter life when incoming water is from a very clean well?
It depends on if you have any the debris. If you have a prefilter for the larger particles, that would make the filter life longer.
Alma have 2 sediment filters inline
David Wilson Do you have any carbon block?
Alma no, water tested yearly, always very good, no reduction in flow or well pump pressure with regular filter changes, dug well in late ‘79
David Wilson Then you should be good on the filters. We still recommend replacing them no longer than 1.5 years because of bacteria.
