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

Where these two actually differ

• We flag Microbial growth (bacteria, mold) in pitcher housing, Activated carbon filter degradation and bypass, Bacterial regrowth if water stored too long and Inadequate contaminant removal claims without verification 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 activated carbon filter cartridge, BPA-free 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 level, close enough that price and fit should decide it rather than our grade.
