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

Where these two actually differ

• We flag Bacterial growth and microbial contamination, Activated carbon filter exhaustion and ineffective filtration, Plastic degradation and leaching from physical damage and Water quality claims accuracy and testing on the Soma 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 Soma.
• The Soma is BPA-free plastic pitcher with activated carbon 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 level, close enough that price and fit should decide it rather than our grade.
