I had the pitcher for a few years but this is really great on so many levels: 1) holds more water (obviously) 2) it’s glass - not plastic! 3) I added 5 medium size shungite stones in there instead of in my glass or water bottle. I use Zero water for boiling water, washing fruits and vegetables, making coffee, and I love the tester pen (even though you can taste the difference when it’s time to change the filter). I’m a very satisfied customer :)
