Ben Vorlich Tartan Axminster Carpet | Wool Plaid vs Compelling Choice II Textured Indoor Carpet Polyester SS020-12-L: which is safer?

Where these two actually differ

• We flag Formaldehyde and VOC off-gassing, Azo dyes and heavy metals in colorants, Dust and dust mite allergens and Moth and insect infestation risk on the Axminster and not on the Stainmaster.
• We flag Volatile organic compounds (VOCs) from stain-treatment finish and off-gassing, PFAS in stain-resistant treatment (covered separately by PFAS grade, but noted here for co, Formaldehyde resins in polyester backing and adhesives and Antimony in polyester fiber as flame retardant catalyst on the Stainmaster and not on the Axminster.
• The Axminster is wool plaid, Axminster weave where the Stainmaster is Polyester with unspecified stain-resistant 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 Axminster is the one to buy.
• We are less certain about the Stainmaster grade, at 35% confidence against 72%, because it discloses less.
