Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs Joypur Portable Electric Water Filter Bottle, 22oz Purifier for Camping, Travel & Daily Use: 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 PUR.
• We flag Bacterial growth in stagnant electrolysis chamber, Plastic housing leaching (unspecified polymer), Electrolysis byproducts (unspecified) and Filter cartridge compatibility and counterfeit risk on the PUR and not on the Aquamira.
• The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the PUR is Activated carbon filter cartridge (standard type); plastic housing, 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.
