Where these two actually differ
- We flag Silicone gasket degradation, Bacterial growth in vacuum seal and Surface corrosion under acidic conditions on the Klean Kanteen and not on the Smart Seal.
- We flag BPA/BPS in polycarbonate or copolyester body or lid, Phthalates in plasticizer or seal elastomer and Lid and seal material leaching on the Smart Seal and not on the Klean Kanteen.
- The Klean Kanteen is Stainless steel body, silicone gasket lid seal where the Smart Seal is Plastic container, lid material unspecified, which is most of the difference in these two grades.
- The gap is 30 points, wide enough that this is not a close call, and the Klean Kanteen is the one to buy.
- We are less certain about the Smart Seal grade, at 35% confidence against 82%, because it discloses less.
