10-Cup Ready Pour Pitcher vs Culligan 12-Cup Water Filter Pitcher with ZeroWater Technology: which is safer?

Where these two actually differ

• We flag Bacterial growth in filter media if neglected, Ion-exchange resin exhaustion and mineral release, Inadequate contaminant removal (performance misalignment) and Plastic pitcher degradation from sunlight or heat on the Culligan and not on the ZeroWater.
• 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 Culligan.
• The Culligan is BPA-free plastic pitcher with carbon/ion-exchange filter where the ZeroWater is Activated carbon and ion-exchange resin filter media, 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.
