Product review (5 stars): Excellent Filtration
My order was the result of considerable search for a filter for my Samsung refrigerator that was economically priced.  To my delightful surprise, I was able to purchase a three-pack of Tier1 from Discount Filter Store for less than others wanted for a single filter!  After the installation, the water tasted considerably "sweeter" than previously.  I have only praise for Tier1 water filters, and have already recommended it to some friends.
