I've used Zero water filters for ten years. They are truly the best water filters. Lately I don't seem to be getting as many refills out of them as I used to, though. I used to get almost 5 weeks out of one filter. Now I barely get 3 weeks. I measure the TDS of the tap water constantly. It has gotten worse, but not that worse. I don't know if Zero is using less filter material, or what, but something has changed.
We have been using Zero Water Filters for 4 years. Very Happy with results. Not happy with the new seal. Definitely prefer the screw-on caps.
I would recommend this to a friend!
