ZeroWater Replacement Filter

According to the manufacturer, this 5-stage replacement filter for your ZeroWater jug removes up to 99.6% of total dissolved solids (TDS) from tap water and is NSF-certified for lead and chromium reduction. This gives you a neutral base if you want to mineralise your own brewing water for filter coffee. The TDS meter that comes with ZeroWater jugs tells you when it is time for a new filter.
