Gozero Next-gen Instant Water Filter Pitcher, Rechargeable vs Culligan 12-Cup Water Filter Pitcher with ZeroWater Technology: which is safer?

Where these two actually differ

• We flag Bacterial colonization in filter media, Rechargeable indicator or electronic component degradation and Inadequate contaminant reduction if filter is not certified on the Philips 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 Philips.
• The Philips is Pitcher body (likely plastic/BPA-free polymer); filter media (activated carbon, ion-exchange resin) 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.
