Ben Vorlich Tartan Axminster Carpet | Wool Plaid vs Shaw Patcraft Streamline Carpet Tile Strie Green 18" x 36" Premium (63 sq ft/ctn): 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 Patcraft.
• We flag Fluorinated stain/water treatment (PFAS class), Flame retardant additives, Volatile organic compound (VOC) off-gassing and Microplastic shedding from pile wear on the Patcraft and not on the Axminster.
• The Axminster is wool plaid, Axminster weave where the Patcraft is Polypropylene carpet tile with unknown stain/water 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 Patcraft grade, at 35% confidence against 72%, because it discloses less.
