What These Numbers Mean for Minnesota Residents

PFAS in Minnesota Drinking Water

Minnesota's regional PFAS composite is 5.4 parts per trillion (ppt), which exceeds the EPA's 2024 enforceable limit of 4 ppt for PFOA and PFOS. Water utilities in Minnesota have until 2029 to comply. In the interim, a point-of-use reverse osmosis filter (NSF 58 certified) removes 95%+ of PFAS at the tap.

Lead in Minnesota Tap Water

Lead contamination in Minnesota averages 4.2 ppb at the 90th percentile. This is within the EPA's action level but above the zero health goal. Lead pipes in pre-1986 homes remain the primary risk factor — consider an NSF 53-certified filter as a precaution.

PM2.5 Air Quality in Minnesota

Minnesota's annual average PM2.5 is 7.4 µg/m³. This meets the EPA annual standard (9 µg/m³) but exceeds the stricter WHO guideline of 5 µg/m³. A HEPA air purifier in sleeping areas is recommended, particularly for children and people with respiratory conditions.

Filtration Recommendations for Minnesota

  • PFAS concern: AquaTru Countertop RO (NSF 58) removes >95% of PFAS — the most effective countertop option. Shop AquaTru →
  • Lead concern: Any NSF 53-certified carbon block filter removes lead at the tap. An RO system covers both PFAS and lead. Shop Berkey →
