Ben Vorlich Tartan Axminster Carpet | Wool Plaid vs 8-in x 8-in Impassioned II 68.3-oz sq yard Polyester Textured Indoor Carpet: 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 Stainmaster.
• We flag Flame retardants (brominated or phosphate-based), VOC and aldehyde off-gassing from adhesives and finishing treatments, Dust and particulate trapping from dense pile and Degradation of stain coating and recontamination under heat or aggressive cleaning on the Stainmaster and not on the Axminster.
• The Axminster is wool plaid, Axminster weave where the Stainmaster is polyester carpet with stain-resist 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 Stainmaster grade, at 35% confidence against 72%, because it discloses less.
