Filters last just about 14 days before needing replacement, which is expensive. They work really well when they are new but fade too fast.

Thank you for contacting ZeroWater. Due to the amount of variables involved we try and stay away from using time to determine filter life, instead we use gallons, a more constant form of measurement. Filter life is based solely off of the quality of the water being filtered. The higher the tap water is in dissolved solids the shorter the filter life will be.
Zero Water filters deserve no less than five stars, one for every stage! The BEST filter on the market. Bottled water cannot compare, no excessive plastic waste, better for the planet and if you test some of those bottled waters, you'd be shocked.
This quantity is the best value for us right now. We may go to scheduled deliveries soon, once we have a good handle on how often we need to switch to a new filter.
Each filter last me about 7-9 days. Not sustainable, practical or efficient
