This has been my big concern. Our tap water is so heavily chlorinated that you can smell it. I shower in it everyday. Quite long and hot showers at the moment, winter you know. Plus I have a hot tub. I only put chlorine in the hot tub every couple of weeks and only a small amount and never when I am in it. But I do go in it everyday. I would love to get a filter for my shower, but my husband already thinks I am nuts and spending too much money on all this health nonsense. What is a poor girl to do. Keep uping the Iodine I guess.
