Home Calais Geometric Machine Washable Area Rug vs Rib Wool 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 and not on the Parachute.
• We flag Heavy metals in wool dyes, Pesticide residues in raw wool fiber and Dust and fiber inhalation from shedding on the Parachute and not on the Mohawk.
• The Mohawk is Polypropylene with unspecified stain/water-resistant treatment where the Parachute is wool fiber, no reported topical treatment, 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 Parachute is the one to buy.
• We are less certain about the Mohawk grade, at 45% confidence against 78%, because it discloses less.
