We get our drinking water a well on our property. It is very hard water and has a bit of a aftertaste. After setting up the water filter, I tested our tap water with the tester provided with this filter system and it showed 221 ppm. I tested a glass of filtered water and it went to 0 ppm. The water tastes great and it does not leave any hard water residue on my Keurig or Mr. Coffee coffee makers. I feel better about the water we are drinking and cooking with. *Just note that it does not include a base. We had previously purchased a ceramic base and it works perfectly with it.

works great and the water is WAY better than the crappy city water I had filtered through a PUR water filter, even though PUR water filter did a decent job too.

From yucky to delicious water

This system holds 21/2gallons of filtered water. It is easier to store on a stand than the pitchers that take up counter space. The jug and stand are sold separately. We bought this for grand daughter ad she is on well water. We purchased ours 8 years ago. We clean the unit and change filter every 2 to 3 months as needed. I highly recommend this product but it does need a stand and stone crock jug.
