3M Aqua-Pure Whole House Water Filtration System AP11T vs Whole House Water Filter System: which is safer?

Where these two actually differ

• We flag Bacterial growth and biofilm in filter cartridge, Carbon dust ingestion (loose media post-installation), Ineffective contaminant reduction if cartridge oversaturated and Uncertainty regarding PFAS removal capability on the Aqua Pure and not on the Culligan.
• We flag Plastic housing leachables, Ion-exchange resin shedding, Bacterial regrowth in filter media and Contaminant breakthrough if filter is undersized or clogged on the Culligan and not on the Aqua Pure.
• The Aqua Pure is Activated carbon filter media; plastic housing and cartridge frame where the Culligan is Activated carbon and ion-exchange resin filter media; plastic/polymer housing, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
