NSF CERTIFICATIONS AND LAB TESTS
“WHICH FILTER SHOULD I CHOOSE?”
LET’S GET STARTED:
Are you on City water? Choose any of the 4 filter options.
Are you on Well water? Choose Doulton or Cerametix (scrubbable in the event you have higher iron/manganese levels etc. If you have no Iron/Manganese issues the Nano is a great Well water option as well.
Lab Tests are available at the links above. For higher Fluoride levels in city/county water, the Doulton Ultra-Fluoride is recommended.
