Our AquaTru countertop and under sink purifiers all use the same filters. These filters have the same filter lives (based on time), regardless of which purifier you use. However, while our VOC filters (Classic and Alkaline) have the same filter life of 12 months no matter which purifier you use them in, our countertop purifiers are certified to a filter life of 600 gallons, while our under sink purifiers are certified to a filter life of 360 gallons. Why is this?
Our filters are actually tested to work beyond our stated 600 gallons. However, since our filters are tested and certified to rigorous NSF standards to prove they effectively remove contaminants for the full life of their filters, there are certain safety factors this certification requires us to account for in order to keep consumers safe. Our countertop purifiers have a built-in change filter alert, which allows us to claim a longer filter life because they let you know when the filters need to be replaced. Since our under sink purifiers don’t have this same built-in change filter alert, certification requires a larger safety buffer, which is why the gallon life is 360 gallons. All you have to do is change your VOC filters (Classic or Alkaline) every 12 months, regardless of your purifier, and you’ll be able to continue to transform your tap water into the pure, delicious AquaTru water that allows you to live your life and thrive.
