Product review (1 stars): FAILED TESTING SEE PHOTOS!
UPDATE:  note sure why ALL my photos are not showing: this thing is WORSE than my old used filter that was over a year old!

I tested this filter up against Poland Spring bottles of water my original more than a-year-old PUR filter and regular tapwater.  The Poland Spring bottles of water registered at 29 ppm, the old PUR filter registered at 150 ppm, the new more pure filter that was purchased here registers at a dismal 173 ppm, and the regular tapwater registers at 210 ppm.
how can this new filter register worse than an old filter already in my refrigerator for over a year???????

Will be returning immediately. Thank God for Amazon customer service
