An UltraStream filter will last 12 months – depending, as always, on source water conditions and use. Our 12-month recommendation is based on a family of 4, who use about 2.1 gallons per day (8 glasses / 65 fluid oz each) for drinking and cooking.
If you use less, your filter may last longer. More – and you’ll need to replace sooner.
Filter life always depends on the quality of the input water. The more unwanted stuff in the water, the harder the UltraStream has to work. For the vast majority of users, 12 months of protection and performance is no problem.
When the filter is replaced (a simple 3-minute job) your UltraStream returns to full filtration, pH, hydrogen and antioxidant power.
