Why Klean Kanteen Double Wall Vacuum Insulated wins, and what it beats

Every grade on this page is one sum. A category starts from a baseline, each disclosed material or coating adds risk points, and each thing the brand or a third party has published takes them away. Below is that sum for the winner, then for 3 products it beats, so you can see exactly where the 75 points between the top and the bottom of this lunch boxes ranking come from.

Common questions about PFAS in lunch boxes

Are lunch boxes PFAS free?

162 of the 174 lunch boxes PFAS Authority has graded reach its 70 point pass mark for PFAS and other toxins, 93.1% of the category, as of October 2026, and 12 score below it. The highest graded is Klean Kanteen Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid at 100 out of 100. The lowest graded is Oggi Bentgo Kids Stainless Steel Leak Resistant Lunch Box at 25 out of 100.

Are lunch boxes non-toxic?

162 of the 174 lunch boxes we graded clear our screen and 12 do not. Non-toxic is not a defined or regulated term, so what we can tell you is what our graders recorded. Beyond PFAS, the hazards found or left unruled-out on lunch boxes in this category are microplastics, vocs and off-gassing, heavy metals, bpa and bisphenols, phthalates. The highest graded here is Klean Kanteen Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid at 100 out of 100.

Which are the safest lunch boxes to buy?

On our grades, Klean Kanteen Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid at 100 out of 100, which we band as Excellent. Then Snapware Meal Box Glass at 80. These are model-based assessments from published materials, ingredient lists, certifications and disclosures, not laboratory tests, so treat them as the lowest risk we can evidence rather than a safety guarantee.

Which lunch boxes grade best for PFAS?

Klean Kanteen Double Wall Vacuum Insulated Stainless Steel Food Canister Container with Leak Proof Lid, at 100 out of 100, which we band as Excellent. It is stainless steel body, silicone gasket lid seal. The runner up is Snapware Meal Box Glass at 80.

Which lunch boxes should I avoid?

The three lowest scoring we hold are Oggi Bentgo Kids Stainless Steel Leak Resistant Lunch Box at 25, Hydro Flask Carryout Lunch Tote at 25, Built NY - Puffer Lunch Box - Abstract Mulberry at 25. The problem with the first is that stainless steel core is lower concern; seal composition unclear.

How can you tell if lunch boxes contain PFAS?

In this category we check for bpa & bisphenols, phthalates, microplastics. Plastic-hardening chemicals linked to hormone disruption. Language like stain resistant, water repellent or easy release usually means fluorinated chemistry even when PFAS is never printed on the box.

Which lunch boxes brands have not published a PFAS statement?

We found no PFAS statement from 35 of the brands we scored in this category, including Aladdin, Bentgo, Bento Tek, Built NY, Decathlon, EasyLunchboxes. That is what our research turned up, not proof a brand has never said anything, and a missing statement is not evidence of harm. It is the reason those brands cannot score well on disclosure.

Do you lab test lunch boxes?

No. We score from published ingredient lists, materials, certifications, disclosures and third party lab results where they exist. Where a product has been independently tested we use that result and say so.
