Where It Comes From
Stain-/water-resistant treatments on textiles, upholstery, carpets, leather, outdoor gear, and paper/packaging; releases can occur during manufacture, use, and disposal [1][2].
How You Are Exposed
Breathing or ingesting indoor dust from treated items; washing that sends residues to wastewater; and drinking water/food contaminated by PFAS formed as breakdown products (e.g., PFOA, PFNA) [1][2].
Why It Matters
PFAS last a long time, build up in people and wildlife, and some are linked to high cholesterol, reduced vaccine response, liver/thyroid changes, pregnancy risks, and cancer (PFOA) [1][2][3].
Who Is at Risk
Workers handling PFAS; households with many treated carpets/upholstery; young children (more dust intake); pregnant people; communities near PFAS-contaminated water sources [1][2][4].
How to Lower Your Exposure
Choose PFAS‑free products; vacuum with HEPA and wet‑dust; ventilate rooms; limit grease‑resistant packaging; wash hands; use certified RO or activated‑carbon water filters and consider testing your water [2][4][5].
