The most important thing about a water filter is whether it does the job it's supposed to do. So far I have found no information from Soma on what contaminants the Soma Water Filter filters out, or any third-party documentation on this. Lead? Chloroform? Arsenic? Other chemicals? Flouride? Pesticides? There's lot of hype about how pretty the decanter looks on a dining room table, and the fact that black specks don't appear in the container or in water as its poured. While I applaud the fact the filter is biodegradable, and the container is made of glass, not plastic, wise consumers need more facts, and a company that purports to be so environmentally conscious should be more forthcoming.
