XL 44-Cup Water Filter Dispenser with 2 Genuine PUR Filters vs 40-Cup Glass Water Filter Dispenser: which is safer?

Where these two actually differ

• We flag Plastic housing leachables (BPA, bisphenols), Bacterial growth in filter or housing, Activated carbon filter exhaustion and contaminant breakthrough and Housing degradation from chlorine or minerals on the PUR and not on the ZeroWater.
• We flag Ion-exchange resin cartridge composition opacity, Bacterial or mold growth in housing and spigot and Polypropylene plastic durability and UV exposure on the ZeroWater and not on the PUR.
• The PUR is Plastic dispenser housing, activated carbon filter media where the ZeroWater is borosilicate glass, plastic pitcher housing, ion-exchange resin cartridge, 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.
