200-Gallon Long-Life 10-Cup Large Water Filter 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 maintenance neglected, Off-gassing or odor from new filter cartridge, Deterioration of plastic housing gaskets and seals over time and Inadequate contaminant removal if filter is counterfeit or past expiry on the Waterdrop 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 Waterdrop.
• The Waterdrop is Activated carbon filter media, plastic pitcher body 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.
