Product review (5 stars): Quality Product
I purchased the filters after not being able to find them locally. I was very happy with the speed of delivery, the cost and the quality of the product. I have a whole house water softner system but our water is still somewhat hard, which means I usually have to chage these filters before the "listed" average use time. I found that with this product I no longer have to change them as much, and that is great!
