Mamavation used an EPA-certified lab to do this testing. No fluorine was detected in any of these products sent to the lab in 2020 and 2021. The Level of Qualification (LOQ) for testing was 10 parts per million, therefore if products had fluorine at lower levels, the test would not find it. We cannot guarantee these brands will continue to test the same. This was only a snapshot in time to help guide you in purchases. Most brands are using a thin layer of polyester or nylon to capture up to 5 tampons’ worth of heavy flow and keep it in your panties.
