3M Aqua-Pure AP802B Whole House Filter Housing vs Everpure FXI-22 FX Water Filtration System: which is safer?

Where these two actually differ

• We flag Bacterial growth in spent cartridges, Polypropylene stress fractures under thermal or pressure stress and Cartridge bypass or seal degradation on the Aqua Pure and not on the Pentair.
• We flag Bacterial growth in filter cartridge (maintenance-dependent), Resin bed breakthrough (ion breakthrough) and Carbon dust or fines in water (post-installation) on the Pentair and not on the Aqua Pure.
• The Aqua Pure is polypropylene filter housing, carbon/sediment cartridge where the Pentair is activated carbon, ion-exchange resin cartridge, 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.
