Jacksonville doesn't have terrible water, but I don't like the taste of it, or smell of it. Since I have a refrigerator with a water filter, I don't have to deal with the sulfur, pharmaceuticals, and whatever else sneaks into the Jax water supply. But that's a totally different review. This one is all about shower water, and most of us don't drink it, so why get a shower filter? Well, if you want slightly less hardness without a water softener, this might help a little.
