Prestige Water Filter Pitcher - Spacious and Efficient Dark Blue vs Sustainable Pitcher: which is safer?

Where these two actually differ

• We flag Bacterial growth in filter housing if filter cartridge not replaced on schedule and Degradation of housing clarity and seal integrity over years of use on the Aquaphor and not on the Soma.
• We flag Bacterial growth in filter housing, Activated carbon dust in water and Rubber seal degradation on the Soma and not on the Aquaphor.
• The Aquaphor is Plastic pitcher housing, activated carbon and ion-exchange resin filter media where the Soma is borosilicate glass pitcher, activated carbon filter 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.
