Product review (1 stars): Poor quality.
I tried a less expensive filter and it showed.  When I first ran water through this filter, it literally came out blue, then blue-green.  This did not happen with previous filters.  The water cleared after a couple gallons as expected. Now, about 2 months after installing, the chlorine taste is in the water, as if there was not filter at all, like right out of the tap.
My previous filter lasted over 2 years. I will not buy Pure Line filters again.  Pay more for a better quality. I do not want to have any concerns about my drinking water.
