Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs bottle 17 oz White - Unique Design - 1 bottle You Choose: 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 Plastic lid material unspecified, Lid gasket degradation and Bacterial growth in vacuum chamber or lid crevices 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 vacuum-insulated walls; BPA-free plastic lid, 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.
