Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs 24oz Wide Mouth Flex Straw Cap: 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 Polymer cap/straw composition opacity, Bacterial growth in cap seals, Rubber gasket degradation over time and Thermal stress on polymers from temperature shock 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 bottle; polymer cap and straw, 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.
