Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs 5 Gallon Refill 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 Culligan.
• We flag BPA and BPA analogs in polycarbonate, Bacterial growth and biofilm in stored water, Filter resin leaching and exhaustion and Microplastics from bottle degradation on the Culligan and not on the Aquamira.
• The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the Culligan is polycarbonate or polyethylene plastic bottle; 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.
