27oz Wide Water Bottle with Loop Cap vs Epic Water Filters Nalgene OG Water Bottle with Filter: which is safer?

Where these two actually differ

• We flag Cap or closure contamination and Bacterial or mold growth from moisture retention on the Klean Kanteen and not on the Nalgene.
• We flag Bacterial growth in filter (maintenance-dependent), Filter housing seal degradation and Activated carbon saturation without visual warning on the Nalgene and not on the Klean Kanteen.
• The Klean Kanteen is 18/8 stainless steel, no interior coating where the Nalgene is Tritan copolyester bottle, activated carbon filter, 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.
