- · When manufacturers listed contaminants in different ways, we left them as shown by the manufacturer, rather than try to align contaminant ‘titles’.
- · Manufacturers listed categories differently. To simplify and standardize, we simply listed in alphabetical order.
- · When information was provided in more than one way or place, we combined on this chart.
- · An asterisk in the chart * indicates Triholomethanes, the byproducts of chlorination. Please note that some show total trihalomethanes, others separated them in testing. We have shown them as the manufacturers did.
- · We were adding data from a chart found on a PuR site showing % of contaminants removed – providing more detail than the higher levels which showed a ‘X’ rather than a percent. Oddly, the next day we weren’t able to relocate it again. If you can tell us where that chart is, we’ll complete replacing the Xs with percentages.
- · The Brita statement on their site saying theirs is the only pitcher that removes Cryptosporidium and Giardia at not accurate.
- · Most, not all, Seychelle water filter pitcher results from County of Los Angeles labs, using EPA protocols and NSF Standards 42 and 53.
- · Brita reports it removes insoluble lead to the NSF standard - not soluble.
- · Brita apparently chooses, for the most part, not to list specific contaminants filtered. (We can understand this approach. How much is filtered can vary based on amounts and length of time that the filter has been in use.)
- · A blank in any box indicates only that we found no claim from the manufacturer.
- · We have done our best to present this information accurately as presented by the manufacturers, based on the data we found on websites in June and July of 2010.
- · When tests showed different results, we used the more recent tests (based on the understanding that the products are being improved).
- · Where we have seen significant discrepancies, we have shown them.
- · Updated or corrected information respectfully submitted will be corrected on this page.orts it removes insoluble lead to the NSF standard - not soluble.
