PUR filter technology is awesome! So easy to install. My son installed it within 5 minutes. Did I notice a difference? Yes I did instantly! The taste is seems better.  It claims to remove 99% lead , 96%! of mercury , 92% pesticides, & reduces chlorine. It also has a clean sensor monitor. Filter is suppose to last 3 - months - so I guess I have to let you know. This is great because I don’t drink out water where we live. So I am very happy that I know I am doing my best to give my grandson & kids clean water. Not to mention I won’t have to keep buying water. I had other pictures to show but unfortunately they wouldn’t upload.
