Hard to evaluate these without being a scientist to measure the quality of the water and if they truly treat 200 gallons as they indicate on the package. I am rating this as one star specifically due to the volume of water that I am getting from my in the door water dispenser...it is extremely slow and takes forever to fill up water bottles and the like. I have had several filters and none of them are as slow as this one; none come close. The water is barely a trickle.

Bottom line very dissatisfied and will never use this brand again
