Zero Water is amazing. We used to use Brita but found that it didn't take all the taste of chlorine out of our water when we were on town Water. So we bought Zero Water. The filter is large and super heavy duty. It has several layers of filtration and comes makes the water come out clear and refreshing. It comes with a tester so you can see if there are any solid particles left in the water. It is the freshest tasting water out there.
