What certification to look for

The NSF/ANSI standard that certifies reduction of each contaminant — match it on any product’s label, whatever the brand.

PFAS

NSF/ANSI 53, 58, or P473

Reverse osmosis or activated-carbon block — RO and certified carbon are the most effective PFAS barriers.

Lead

NSF/ANSI 53 or 58

Carbon block or reverse osmosis

Trihalomethanes

NSF/ANSI 53

Activated carbon

Nitrate

NSF/ANSI 58

Reverse osmosis — Carbon filters do NOT remove nitrate — use RO, ion exchange, or distillation.

Arsenic

NSF/ANSI 53 or 58

Reverse osmosis or arsenic-specific adsorptive media

Chlorine

NSF/ANSI 42

Activated carbon

Mercury

NSF/ANSI 53

Carbon block or reverse osmosis

Hardness

NSF/ANSI 44

Cation-exchange water softener

Sediment

NSF/ANSI 42

Mechanical / sediment filtration

Not sure what to filter?

Test first, then filter

A lab test tells you exactly what’s in your water — so you don’t pay for filtration you don’t need.
