Where these two actually differ
- We flag Phthalates or plasticizers in BPA-free plastic, Microplastics from polymer degradation, Dye stability and leaching from daisy print and PFAS in plastic additives or manufacturing on the Ello and not on the Klean Kanteen.
- We flag Powder-coat cap degradation over time, Bacterial biofilm in cap threads and seals and Thermal stress on seals at extreme temperatures on the Klean Kanteen and not on the Ello.
- The Ello is BPA-free plastic, stainless steel lid where the Klean Kanteen is Stainless steel bottle, stainless steel cap, which is most of the difference in these two grades.
- The gap is 25 points, wide enough that this is not a close call, and the Klean Kanteen is the one to buy.
