Self-Purifying Water Bottle vs 27oz Wide Water Bottle with Loop Cap: which is safer?

Where these two actually differ

• We flag Plastic bottle leachables (BPA/BPS and phenolic resins), Bacterial growth in filter and bottle interior, Activated carbon shedding and particulates and Unverified contaminant reduction claims on the Uvio and not on the Klean Kanteen.
• We flag Cap or closure contamination and Bacterial or mold growth from moisture retention on the Klean Kanteen and not on the Uvio.
• The Uvio is plastic bottle with carbon/activated carbon filter cartridge where the Klean Kanteen is 18/8 stainless steel, no interior coating, 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 Uvio grade, at 45% confidence against 92%, because it discloses less.
