Ben Vorlich Tartan Axminster Carpet | Wool Plaid vs Impress TH904 Residential Carpet: 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 Tarkett.
• We flag Fluorinated stain treatment (PFAS family), Volatile organic compound (VOC) off-gassing from backing and adhesives, Microplastic and fiber shedding and Backing material degradation and mold risk on the Tarkett and not on the Axminster.
• The Axminster is wool plaid, Axminster weave where the Tarkett is Polypropylene pile with stain/water 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 Tarkett grade, at 45% confidence against 72%, because it discloses less.
