MaxClear Technology Gravity Countertop Water Filter System vs 40-Cup Glass Water Filter Dispenser: which is safer?

Where these two actually differ

• We flag Bacterial growth in filter media and housing, Activated carbon dust or fines in filtered water and Chlorine or chloramine taste/odor breakthrough on the Culligan 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 Culligan.
• The Culligan is Activated carbon, ion exchange resin, polypropylene 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.
