A countertop water purifier that gets rid of 78 toxins and chemicals including lead, chlorine, pesticides, fluoride, PFOA, and more. It uses 4-stage reverse osmosis, but doesn’t waste water. For every gallon of dirty water you put in the Aquatru, you will get 3/4 gallon of filtered water. Easily tells you when the filters need to be changed and it is so easy to clean! This is the water purifier that my family uses!
