Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs S well Traveler: 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 S'well.
• We flag Filter composition leachables (BPA, resins, adhesives), Bacterial/microorganism growth in filter media if unmaintained, Filter effectiveness for contaminant removal claims and Off-gassing or odor from new filter media on the S'well and not on the Aquamira.
• The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the S'well is Stainless steel exterior, internal water filter (carbon/ion-exchange), 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.
