Water Filter Pitcher with 1 Filter vs Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification: which is safer?

Where these two actually differ

• We flag Bacterial growth and biofilm in filter cartridge, Housing material brittleness or cracking and Activated carbon dust or particles in first use on the Waterdrop and not on the Aquamira.
• 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 Waterdrop.
• The Waterdrop is Plastic pitcher (likely polypropylene or BPA-free plastic); activated carbon filter where the Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical, 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.
