I have tried these and cheaper white waters. I couldn't believe there was a BIG difference and they were so much better. After 2.5 weeks I got a change from 6.5 to 10.5 with this on a new gauge and drops to test. It's perfect I would say. They are trying. The white filters were still 6.5 (no change at all) after almost a week of use? I was wondering why white filtered water was repeatedly giving me acidic indigestion! Don't buy white filters to save a few FRNs (pieces of paper) as they don't work for alkaline water in my experience. One of those blue filters was in a Lake Industries jar. White from Mavea, I like that. By the way, the filters are exactly the same size. Welcome back!
