I just use my big 10", filter.
It's a filter that goes under the sink for the cold water. I chucked the filter that came with it, which only removes about 60% of chlorine, for the next more expensive filter, that does 97+%. Total cost under $50. Better tasting water, as well.
Much better and cheaper long term solution than those little brita or faucet filters, buying spring water, or using camden tabs or KMS.
