Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs UltraPress Water Filters: 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 Grayl.
• We flag Bacterial growth in filter media and Activated carbon filter degradation and replacement compliance on the Grayl and not on the Aquamira.
• The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the Grayl is Stainless steel, plastic housing, activated carbon/coconut shell filters, 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.
