I was the person who asked the first question above (about how this filter differs from the previous version). Reshape's reaction is correct: this new filter works better than the previous one. BIG! but whatever they did to improve the flow, it came at the cost of a much WORSE pH. My tap water is more alkaline than water with this "new" filter (I live in Hawaii, but that doesn't matter). Incidentally, I also tested the old filters and they were significantly better than the new ones in terms of alkalinization. Please test your water and see if you have had a similar experience (I hope not). Complete crap
