Awhile ago, Brita came out with its Fill and Go sports bottle, with a Brita filter fitted inside a reusable plastic water bottle. Brita claims that the activated carbon filter reduces chlorine, smells, and odors from tap water.

Now there's a new company trying to edge its way into the sports bottle-with-filter market: Fit N Fresh. The company claims it uses a "two-part filtration system" to remove impurities from your tap water. First, the water passes through a carbon filter (just like Brita), and removes 50% of the chlorine. Next, the filter offers an added benefit of resisting against bacteria that can settle in your filter throughout the day "through air, contaminated surfaces and the act of drinking itself." Oh - and it's certified by the Water Quality Association.
An interesting note: the company doesn't mention protection against the plastic leeching Bisphenol-A into our water, which to me is a little more disturbing than some extra germs.

My favorite by far, though, is the LifeSaver water bottle, which can purify 4,000 to 6,000 liters of water with one filter, and filters out both bacteria and viruses. Perhaps not as practical a solution for day-to-day use as Brita or Fit N Fresh, but It is expected to prove extremely useful in natural disaster situations, and has already caught on within the military to bring fresh water to soldiers.
