Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs Culligan ZeroWater Official Replacement Filter 4-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 ZeroWater.
• We flag Microbial growth in exhausted or improperly maintained cartridge, Ion-exchange resin particle shedding, Incomplete removal of volatile organic compounds and chlorine byproducts and Lack of third-party certification and transparency 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 (primary filtration 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.
