Cut Through the PFAS Filter Confusion

PFAS headlines are scary. Filter marketing is confusing. We break down which filters actually remove forever chemicals, what the certifications mean, and what you really need for your home.

EPA PFAS Rule Is Enforceable

The EPA set limits of 4 parts per trillion for PFOA and PFOS. Public water systems must begin monitoring by 2027 and comply by 2031. When test results become public, expect a surge in consumer concern. Now is the time to understand your options.

PFAS Myths vs Facts

The misconceptions that cost people money and leave families unprotected.

Myth: "Zero TDS means zero PFAS"

TDS meters do not detect PFAS. A reading of 000 tells you nothing about forever chemicals in your water.

Myth: "Any HEPA-style filter removes PFAS"

Only filters with NSF/ANSI P473 certification are verified for PFAS removal. Marketing claims without this certification are unproven.

Myth: "Boiling water removes PFAS"

Boiling concentrates PFAS — it makes the problem worse, not better. PFAS are called 'forever chemicals' because they resist heat breakdown.
