Oil Less Fryer Air Fryer 16 Quart Replacement Clear Glass vs Dual Easy Fry Air Fryer 8.3 L: which is safer?
Big Boss Oil Less Fryer Air Fryer 16 Quart Replacement Clear Glass is the clear pick. Tefal Dual Easy Fry Air Fryer 8.3 L carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ
- We flag Thermal shock and fracture and Edge chipping and glass fragments on the Big Boss and not on the Tefal.
- We flag PTFE thermal decomposition / fume risk, Coating degradation and microparticle release, Aluminum substrate leaching (if present) and PFAS in manufacturing or coat precursors on the Tefal and not on the Big Boss.
- The Big Boss is borosilicate glass, bare uncoated where the Tefal is PTFE nonstick coating (Teflon-type) on air fryer cooking surfaces, which is most of the difference in these two grades.
- The gap is 70 points, wide enough that this is not a close call, and the Big Boss is the one to buy.
Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
