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 unmaintained, Filter performance claims vs. actual contaminant removal and Degradation of plastic seals and lid components over time on the Contigo and not on the Aquamira.
- The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the Contigo is BPA-free plastic bottle, replaceable 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.
