Research into the comparative effectiveness of water filter systems is patchy, mostly due to the varying qualities of tap water, which means we find different results from region to region.
However, a study conducted in North Carolina (published in the journal Environmental Science and Technology Letters, 2020) found that “All under-sink dual-stage and reverse osmosis filters tested showed near complete removal for all PFASs evaluated. In contrast, all other filters containing activated carbon exhibited variable PFAS removal.”
