Calais Geometric Machine Washable Area Rug vs Adirondack Rug: which is safer?

Where these two actually differ

• We flag Fluorochemical stain/water-resistant treatment (non-PFAS alternatives unknown), Coating degradation and microplastic shedding and Volatile organic compounds (VOCs) from finishing resins on the Mohawk Home and not on the Safavieh.
• We flag Volatile Organic Compounds (VOCs) from acrylic backing and dyes, Microfiber shedding from polypropylene and polyester blend and Acrylic backing degradation and leachables over time on the Safavieh and not on the Mohawk Home.
• The Mohawk Home is Polypropylene with unspecified stain/water-resistant treatment where the Safavieh is Polypropylene and polyester blend with acrylic backing, which is most of the difference in these two grades.
• The gap is 45 points, wide enough that this is not a close call, and the Safavieh is the one to buy.
• We are less certain about the Mohawk Home grade, at 45% confidence against 72%, because it discloses less.
