I live in Hayward CA, with some of the best city water you can find. It rates 025 on your meter. I just want to get the fluoride out. Any idea how many gallons of water I should be able to get from one filter? My daughter bought an 8 cup pitcher and I love the taste of the water, but realize I need a much larger one. So far I would give this 5 stars except for how long it takes to get a cup of water out of it.
