Ok so after reading and looking up every review on the market and test after test I chose to give a ZeroWater Pitcher a try. Not disappointed at all. I have well water and a very good filtration system on the whole house that i service yearly . Well water tested 075ppm after running through pitcher 000 as advertised but i never thought my water had any taste to it as people have commented how good my water tasted . I believe this pitcher has taken good water and made it perfect. Coffee tastes better , Mixed drinks for the kids taste better . Filters last as long if not slightly longer than advertised! It was so easy to assemble and use my 15 year old and 13 year old daughters test and change the filters when necessary and now have become Fanatics about what water they will drink when not at home!!!For those that post the filter clogging in a short period of time i wonder what your water tests prior to running it through the pitcher, that is why i tested mine before and after.
