Review on Watts MAXVOC-975 0.5 Micron Water Filter with 20,000 Gallons Filtration Capacity by Dan West

love it! Absolutely fresh water taste. This update is 8 months later: My water is well water. It took 7 or 8 months for my water to taste metallic (I drink about 4 gallons a day). I'm sure if you live in a city and use the city's water supply it will take a lot longer. This is not a complaint. I was surprised he was doing so well. Based on this, my recommendation for well water users is that the filter should probably be changed every 6 months. After 8 months, the filter was completely brown from top to bottom. So I think an earlier move would be good. And if you live in the city I think this will be an exceptionally good purchase as it will really last quite a long time.
