Product review (5 stars): If I only knew then what I know now...
I was irritated that I had to pay $40+ for a water filter at Lowes. Decided to search the Internet and was pleased to find the WSS-1 offer, so I took a chance and purchased 6 for the savings. Per instructions I ran about a gallon of water through it first. I hit the jackpot - Excellent value for the money.
