Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs 5 Gallon Water Cooler Filtration System: 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 ZeroWater.
• We flag Bacterial growth if unmaintained, Resin cartridge degradation and particle release and Mold or algae in reservoir (light exposure) on the ZeroWater and not on the Aquamira.
• The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the ZeroWater is ion-exchange resin cartridge; 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.
