Ben Vorlich Tartan Axminster Carpet | Wool Plaid vs Advance 24" x 24" Carpet Tile with Colorstrand Nylon Fiber: 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 Mohawk.
• We flag Flame retardants or antimicrobial finishes, Volatile organic compound (VOC) off-gassing from backing or adhesives and Stain-treatment chemical identity and leaching on the Mohawk and not on the Axminster.
• The Axminster is wool plaid, Axminster weave where the Mohawk is Nylon fiber with stain-resistant treatment, which is most of the difference in these two grades.
• The gap is 30 points, wide enough that this is not a close call, and the Axminster is the one to buy.
• We are less certain about the Mohawk grade, at 35% confidence against 72%, because it discloses less.
