Ben Vorlich Tartan Axminster Carpet | Wool Plaid vs Shaw Sample Dynamo 24x24 Carpet Tile 54857: 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 Shaw Industries.
• We flag Volatile organic compounds (VOCs) and off-gassing, Microfiber shedding and chemical transport, Formaldehyde in binders or sizing and Skin and respiratory irritation from undisclosed treatment chemicals on the Shaw Industries and not on the Axminster.
• The Axminster is wool plaid, Axminster weave where the Shaw Industries 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 Shaw Industries grade, at 35% confidence against 72%, because it discloses less.
