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

Where these two actually differ

• We flag Bacterial growth in filter cartridge if maintenance is neglected, Mold and microbial growth in pitcher housing and lid seals, Degradation of activated carbon performance over time and Cartridge compatibility and counterfeit filters 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 Activated carbon and ion-exchange resin 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.
