Product review (1 stars): Poor product
We purchase these filters last April, 2013.  Unfortunately we didn't try to use them until November 2013 (90 days out of warranty).  They were totally useless at removing chlorine taste from our water, even after running 10's of gallons through each of them.  We then purchased another brand, which removed the chlorine taste very effectively.

I would not recommend this product.
