Product review (3 stars): To Short Of Lifespan
I use this filter on a sink mounted spout for pre-filtering water for my steam distiller machine. After initial startup flushing this filter does filter most of the heavy minerals in my Colorado River supplied city water.

I can tell by looking at the dregs at the bottom of the distiller after a cycle since I don't let the distiller run dry or the minerals would fry and be taken up and taint the pure distilled water output, still has some white stuff in the dregs which is probably calcium but more residues show up if I use unfiltered water in my distiller.

Not worth the asking price even for ice cube water, I suggest the Watts 5YR Premier Filter 5-Year/20,000-Gallon Inline filter.
