Ben Vorlich Tartan Axminster Carpet | Wool Plaid vs Microban Solstice 12' Polyester Carpet Tile Light Quartz / 12': 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 Phenix.
• We flag Formaldehyde or volatile organic compounds (VOCs) from backing and adhesives, Microban antimicrobial treatment composition unknown, Flame retardants in backing or yarn and Backing degradation and moisture retention on the Phenix and not on the Axminster.
• The Axminster is wool plaid, Axminster weave where the Phenix is polyester carpet tile with Microban antimicrobial 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 Phenix grade, at 35% confidence against 72%, because it discloses less.
