Culligan 12-Cup Water Filter Pitcher with ZeroWater Technology vs 22 Cup Ready Read Water Filtration Dispenser: which is safer?

Where these two actually differ

• We flag Bacterial growth in reservoir if filter unmaintained or water stored too long, Filter cartridge degradation and particle escape if overfilled or misseated and Ion-exchange resin saturation without visible warning on the ZeroWater and not on the ZeroWater.
• We flag Bacterial growth in filter housing, Ion-exchange resin particle shedding into water, Mineral scale buildup and mold on external surfaces and Cartridge disposal and resin environmental burden on the ZeroWater and not on the ZeroWater.
• The ZeroWater is Activated carbon and ion-exchange resin filter media where the ZeroWater is Ion-exchange resin cartridge, plastic dispenser housing, 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.
