We have softened the water from the well that runs through the Waterwise distiller. I can tell from the smell and taste of the water when the post-filter needs to be replaced without looking at the display. The burner will not start without a post-filter. However, we have so much tannin in our water that I still have to let my drinking water run through Britta.
