Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs Wells Plastic Filter Water Bottle with Autospout Straw Lid: 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 Contigo.
• We flag Bacterial growth in filter if not replaced, Plastic degradation with heat and Seal and lid degradation on the Contigo and not on the Aquamira.
• The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the Contigo is Plastic bottle body, activated carbon filter, 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.
