Do stain-resistant carpets shed PFAS into your home?
Carpets can be a PFAS source indoors. A 2020 Chemosphere study found paired carpet and dust samples in childcare centers carried similar PFAS levels.
What's actually in it
Some stain-resistant carpets and rugs have used PFAS, a large family of chemicals that can help repel oil and water. PFAS can collect in indoor dust.
This matters for young kids because they crawl, play on floors, and put hands in their mouths.
What the research says
A 2020 Chemosphere study tested paired carpet and dust samples from 18 California childcare centers. Median total PFAS levels were 471 ng/g in carpets and 523 ng/g in dust.
The study found strong links between PFAS levels in each carpet and dust pair. The authors concluded that carpets can be both a source and a sink for PFAS indoors.
If you are replacing a rug or small carpet, skip stain-resistant treatments. Choose simple materials like wool rugs, and vacuum existing carpet with a HEPA vacuum to lower dust.
