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

Where these two actually differ

• We flag Bacterial growth and biofilm in stagnant filter media, Activated carbon dust or fines in initial filtered water and Filter cartridge housing failure or seal degradation 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 Plastic pitcher body; replaceable activated carbon/ion-exchange filter cartridge 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.
