Product review (4 stars): Be aware of 'tested' vs 'certified' in the filtration standard
While it isn't certified to remove 100% of cysts and heavy metals, the primary reason we bought this was to counter chlorine odor/taste and provide a final filtration. Better than tap, but I would spring for the more expensive brand name if I had poor or dangerous water to filter. Overall very satisfied and received what I paid for. One star off for the 'tested' vs 'certified' distinction as that could be confusing/misleading for consumers.
