Why we picked it
IAPMO R&T certifies the G3P600 to NSF/ANSI 58 (reverse osmosis, including lead and TDS), NSF/ANSI 53 (including PFOA and PFOS) and NSF/ANSI 42. It is tankless, so it fits smaller cupboards, and sends 1 litre to drain for every 2 litres of filtered water.
Best for
Owners who want the broadest certified reduction at the kitchen sink, including lead and PFOA/PFOS
Not for
Renters, small cupboards without a socket, or people who object to any waste water
