In Phoenix, I've never seen a water filter last because our hard water eats them all up faster than in other places in the US. There must be an ideal combination of filtration systems that others use here and elsewhere that I'm not aware of that last for as long as they do, but standard consumer ones that bring TDS down to zero have very little lifespan here.
I can't imagine what difficulties exist in areas with access to clean water, but I can't expect them to all also be easily filtered outside of processes like solar distillation or something else.
- mattmaroon 1y agoI have a condo in Phoenix, put in a waterdrop RO filter. I change them on the manufacturers schedule, no issues. The TDS was really high before, but I got over 99% reduction. Not 0 but really close.

- kccqzy 1y agoIn the U.S. you probably don't need TDS to be brought down to zero. My water filtration system at home uses reverse osmosis and brings TDS from 150+ to just 20 and the filter lasts more than a year. (Those that bring TDS down to zero might use deionization instead.)
