Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs GeoPress Water Purifier Bottle: 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 exhausted filter cartridge and Activated carbon dust or fines in water on the Grayl and not on the Aquamira.
• The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the Grayl is Silicone, stainless steel, and activated coconut carbon filtration cartridge, 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.
