Title: quality appears to be much lower
Review: I've been using these filters for years. Recently I noticed when I bought a replacement set, that they were made in Mexico. When I used a TDS meter to test the water, it went from 220 ppm (tap water) to about 187 ppm (filtered). I remembered getting much better results when testing the filtered water before. I believe that there is inadequate carbon inside the carbon filter to reduce total dissolved solids (chlorine, lead, mercury, etc.) One thing that is very evident is the redesign of the carbon filter -- it was a solid grey tube before -- now it looks just like the companion filter. Now I have to tear out my GE smartwater filter and install something new.
Is the review positive or negative?
