Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs Wells 24 Oz. Plastic Filter Water Bottle with AUTOSPout Straw Lid and Replacement Filter: 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 cartridge and lid, Plastic body leaching at elevated temperature and Lid seal gasket material unknown on the Contigo and not on the Aquamira.
• The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the Contigo is BPA-free plastic body, activated carbon replacement 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.
