Culligan ZeroWater Technology 22-Cup Ready Water Filtration Dispenser vs 40-Cup Glass Water Filter Dispenser: which is safer?

Where these two actually differ

• We flag Activated carbon dust or resin particle shedding, Bacterial growth in stagnant water or unmaintained filter, Ion-exchange resin leaching or breakdown products and PFAS in filter cartridge materials on the ZeroWater 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 ZeroWater.
• The ZeroWater is Plastic housing, activated carbon + ion-exchange resin filter media 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 level, close enough that price and fit should decide it rather than our grade.
