Do OXO lunch boxes have PFAS?
OXO lunch boxes average 65 out of 100 on PFAS Authority's PFAS and toxin screen across the 7 OXO lunch boxes graded as of October 2026, below the 70 out of 100 median for the 43 other lunch boxes brands graded alongside it.
OXO lunch boxes average Good on our four-band scale. 6 of the 7 we graded are worth buying. That is above 14% of the lunch boxes brands we grade.
PFAS Authority is a scoring system, not a laboratory. We do not test products ourselves. Grades are model-based, built from published ingredients, materials, certifications, brand disclosures and third-party lab results where they exist. See the rubric.
What OXO says and does about PFAS
OXO’s required material disclosures are specific. Its Good Grips Non-Stick Pro bakeware, such as the half sheet pan and jelly roll pan, is listed as containing PTFE, and its Good Grips Nonstick, Good Grips Pro Nonstick and SoftWorks cookware may contain PTFE and PFAS. Its Non-Stick Pro Ceramic Coated bakeware lists only aluminum. OXO also lists PFAS in its Good Grips and SoftWorks nylon utensils, so check which line and material you are buying.
