Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs R2 Replacement Filter Cartridges Single Pack: 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 Instapure.
• We flag Bacterial growth in saturated cartridge, Activated carbon dust or fines and Certification verification gaps on the Instapure and not on the Aquamira.
• The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the Instapure is Activated carbon 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.
