Vitashower SF-1 Shower Filter

January 2009. Shower water filters are designed to deal with chlorine, since that can bother skin and hair for some people. Reviews recommend the Vitashower SF-1 shower water filter, which uses a block of vitamin C, rather than carbon filters that are less effective with warm water. The vitamin C changes chlorine and chloramines (used by some municipal water systems) into harmless inorganic substances. The filter is rated for about 15,000 gallons, but isn't replaceable. That's the major drawback, since you have to replace the whole unit every six to 12 months.

We found the most detailed review of shower water filters at Metaefficient.com, which discusses filter types as well as specific models. Waterionizer.org includes the Vitashower SF-1 in its chart comparing eight shower water filters for specific features and performance factors. The comparisons gain credibility since they don't give the one shower filter sold at this retail site any special advantage.
