Ben Vorlich Tartan Axminster Carpet | Wool Plaid vs Floor Ever Pet Plus 12' Verona Carpet Tile Courtyard / 12': 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 Phenix.
• We flag Stain-treatment chemistry (undisclosed, likely fluorochemical), Volatile organic compound (VOC) off-gassing from adhesive and backing, Formaldehyde in backing or latex adhesive and Microplastic shedding from wear and vacuuming on the Phenix and not on the Axminster.
• The Axminster is wool plaid, Axminster weave where the Phenix is Nylon carpet tile with stain/soil resistance 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 Phenix grade, at 45% confidence against 72%, because it discloses less.
