I might look into the friends of water shower filter the next time my filter cartridge needs replaced. I use one mainly for the chlorine, but the friends of water one also takes care of a high percentage of chlorine.
Too bad they didn't have the larger size than the pitcher, like the type with a spout that are a couple gallons. If I tried to use the pitcher style, I would be filling it up every day. Right now I buy my dog distilled water, but if I used their pitcher filter I could stop buying hers, but we would go through a lot in day.
