Frequently Asked Questions

Does this filter actually remove contaminants or just improve taste?

Yes, the filter actively removes contaminants while improving taste. The 2x reduction in contaminants is verified. Better taste is a side benefit of the actual contaminant removal.

How do I know when the filter needs replacement?

Most pitchers have replacement indicators showing when 40 gallons have passed or 2 months have elapsed. You can also track usage manually. Water quality declining is a sign replacement is due.

Is BPA-free really important or is it just marketing?

BPA-free is important since filters contact water that you drink directly. Standard plastic filters can leach BPA into water. Using BPA-free filters ensures the filter isn't contaminating the water.
