Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs 24 oz 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 Silicone/rubber degradation and leaching and Bacterial or mold growth in cap/straw 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, silicone/rubber straw cap, which is most of the difference in these two grades.
• These two are 5 points apart, close enough that price and fit should decide it rather than our grade.
