Ben Vorlich Tartan Axminster Carpet | Wool Plaid vs Touchstone Le Jardin Area Rug: 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 Karastan.
• We flag Stain/water treatment composition (non-PFAS unknowns), Microplastic shedding from synthetic blend and Coating degradation and reactivation of treatment chemicals on the Karastan and not on the Axminster.
• The Axminster is wool plaid, Axminster weave where the Karastan is Wool blend with 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 Karastan grade, at 35% confidence against 72%, because it discloses less.
