Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs 32 oz Wide Mouth Travel Bottle with Flex Straw Cap in Harbor Blue: which is safer?

Where these two actually differ

• We flag Chemical overdose or misuse, Degradation and loss of efficacy over time, Glass bottle breakage and spillage and Chlorine residue and taste/odor on the Aquamira and not on the Hydro Flask.
• We flag Flex straw material leaching (composition unconfirmed), Bacterial growth in straw and cap crevices and Interior coating degradation and microparticle release on the Hydro Flask and not on the Aquamira.
• The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the Hydro Flask is Stainless steel body and cap; flex straw likely polypropylene or silicone, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
