Gravity Water Filter System 42&372 vs Culligan 12-Cup Water Filter Pitcher with ZeroWater Technology: which is safer?

Where these two actually differ

• We flag Bacterial and microbial growth in filter media and housing, Filter media degradation and particulate shedding, Incomplete contaminant removal and false assurance and Housing seals and gasket degradation on the Aqua Crest 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 Aqua Crest.
• The Aqua Crest is Activated carbon and/or sediment filter media; gravity-fed plastic housing 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.
