Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs Portable Antimicrobial Water Purifier, Travelling, Hiking: 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 PUR.
• We flag Bacterial or mold growth in filter media if not maintained, Ineffective pathogen removal if filter is damaged or misused and Unsubstantiated 'antimicrobial' claims on the PUR and not on the Aquamira.
• The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the PUR is Carbon/ceramic filtration media, plastic housing, 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.
