Product review (1 stars): ... have bought this filter in the past and been satisfied. However
I have bought this filter in the past and been satisfied. However, the last two filters that I bought last year I could only use one because one was bad and would not work. So I figured that was just one of those things and ordered  a pack of two again.  Both  new filters  worked but left a bitter after taste.  This was after running several gal. of water through the filter. I had several people try the water and all had the same result. No one wanted a second glass.  This was completely different then from previous years with this product.  I will have to replace the filter with another company. After three useless filters the cost gets to be prohibitive.
