Our Take
Clearly Filtered's under-sink system is our top pick for carbon-based PFAS removal. Unlike reverse osmosis, it doesn't waste water and retains healthy minerals while removing 99.5% of PFAS compounds. The NSF P473 certification specifically tests for PFOA and PFOS removal — a more rigorous standard than generic NSF 53.
