3M Aqua-Pure AP802B Whole House Filter Housing vs 3WH-HD-S01 Whole House System Large Capacity: 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 Filtrete.
• We flag Plastic housing leachables, Bacterial and biofilm growth in filter media, Activated carbon dust release and Filter media saturation and contaminant breakthrough on the Filtrete and not on the Aqua Pure.
• The Aqua Pure is polypropylene filter housing, carbon/sediment cartridge where the Filtrete is Activated carbon and sediment filter media, plastic 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.
