Product review (5 stars): Its not $50! It works ...
I would never replace a filter for $50! WOuld rather just popl the old one out and trust my local water system which is pretty good . It fit great and no issues right now  50 x 10 years of use $1,000 ++++!
Taste fin, pressure fine ... if you have a problem with those items then pay $50 ...If your in a bad area then perhaps you might want to be a little more picky or anal ... Ive drunk more water these last two weeks then in a year !!
