The proof is in the dust of the home

By Carol Kwiatkowski
In a recently published study, researchers at Harvard University compared the dust of 12 indoor spaces containing conventional furnishings to 12 similar spaces with “healthier” carpets and furniture (reportedly PFAS-free). Dust is a major route for human exposure to PFAS, especially for children who are closer to the ground and have more hand-to-mouth behavior.
The scientists found that levels of PFAS were lower in the spaces with healthier products, meaning that we can make substantial reductions in our PFAS exposures by replacing carpet and furniture that were treated with PFAS.
This is great news. Perhaps even larger reductions could be achieved with other PFAS-free materials, such as flooring, sealants, adhesives, and paints. 
Healthier furniture, healthier dust, healthier people 
Notably, the sum of specific PFAS only accounted for 9% of the total measure, indicating other unidentified PFAS are contributing a large portion of organic fluorine to dust. As we’ve been saying for years, removing all PFAS from products (the class approach) is what is needed.
