FAQ
Choosing between these picks
+How do I know the removal claim is real?
Match the exact model in an NSF, WQA, or IAPMO directory. We label standards certified when that match exists; marketing-only language stays claims-only. Check 42 for taste/odor, 53 for health claims such as lead, 58 for RO, and 401 for named emerging compounds.
+How long does a filter last?
Follow the manufacturer’s rated interval for the cartridge you buy. Breakthrough usually happens before taste changes, so do not stretch a cartridge past its rating just because the water still tastes fine.
+Why do some of these pages show blanks?
A blank means the manufacturer’s own listing did not state the figure. We publish only what the source states rather than estimating a number — an empty cell is more honest than an invented one.
Methodology
Why trust this list
Every row traces to a dated source. We normalize fields and keep blanks honest. We never invent a removal percentage. NSF/ANSI standards are labeled certified when we matched the exact model in a third-party directory; otherwise they stay claims-only.
