Review on Certified Replacement Wamery Pitcher Cartridge: Enhanced Water Filtration by Patrick Matin

I've been drinking (true) alkaline water for about 2 years, so I know the difference (even taking "large" amounts of the relatively expensive chelated magnesium I still had muscle cramps in my legs/calfs ). and only use filtered water) and after 4 weeks I can say they are working well. I still have muscle cramps from time to time. previously used, lasts approx. 6-8 weeks before performance decreases (hours to filter a filling). And half the time, the gasket around the filter isn't thick enough to keep unfiltered water from falling off and mixing with filtered water. The last package worked even worse, performance drops within 2 weeks. Will be using the ZEN 4gl filter system again as the filter is $20 and lasts about 6 months.
