Hub Compact Countertop Water Filtration Device vs 40-Cup Glass Water Filter Dispenser: which is safer?

Where these two actually differ

• We flag Bacterial growth in filter cartridge and housing, Ion-exchange resin shedding or degradation, Activated carbon dust or fines entering water and Improper filter replacement and contamination on the Brita and not on the ZeroWater.
• We flag Ion-exchange resin cartridge composition opacity, Bacterial or mold growth in housing and spigot and Polypropylene plastic durability and UV exposure on the ZeroWater and not on the Brita.
• The Brita is Activated carbon & ion-exchange resin filters; plastic housing where the ZeroWater is borosilicate glass, plastic pitcher housing, ion-exchange resin cartridge, 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.
