Product review (1 stars): Unbelievable
I bought this item in May; but could not have it installed until July.  When the plumber opened the box, he found a used water filter.  Apparently, this was a returned product that was not inspected before it was sold to another customer.  Of course, it's unusable to me.  Unfortunately, the time has expired to return the filter so I just lost over $30.00.  I have never had an experience like this.  Good luck to others who may purchase the water filter.
