Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs GeoPress Water Purifier: 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 regrowth / biofilm in housing, Resin media degradation and shedding, Carbon dust or fines in first-use water and Incomplete contaminant removal claims on the Grayl and not on the Aquamira.
• The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the Grayl is Polypropylene (PP) filter cartridge housing; activated coconut carbon/resin filter media, 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.
