Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs R5 Replacement Filter 2-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 filter media if not replaced on schedule, Loose carbon particles (fines) shed during initial use, Reduced contaminant removal efficacy over time and Lack of removal certification for specific contaminants (e.g., lead, fluoride, nitrates) 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, 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.
