Product review (5 stars): Great filters!
Update: 05/19/26 : I don't have any problems with the taste of the water like other people are claiming. However, when I bought the filters I paid $96.00 in November 2015. I will look online for cheaper prices than Amazon.

bought these filters after I saw on the news that some of North Texas water wells were contaminated with fracking water . These filters will filter out Benzene. I'm not sure if it filters all of the corrosive contaminants  from fracking and I'm not sure there's even any contamination in my drinking water but you never know .
