> Activated carbon filtering removes up to about 75% of PFAS
Common inexpensive non-RO filter systems come with independent test results showing 99% removal of PFOA/PFOS (see e.g https://www.brondell.com/content/UC300_Coral_PDS.pdf). Do we have reason to believe that other PFAS don't filter as easily?
AIHI the shorter PFAS molecules are not captured as effectively by activated carbon.
