3M Aqua-Pure AP802B Whole House Filter Housing vs Aqua-Pure Whole House Sanitary Quick-Change Water Filter System AP904: 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 3M.
• We flag Bacterial growth in filter media if maintenance is neglected, Carbon dust inhalation during cartridge replacement, Cross-contamination from contaminated incoming water if housing seals fail and Incomplete documentation of cartridge material composition on the 3M and not on the Aqua Pure.
• The Aqua Pure is polypropylene filter housing, carbon/sediment cartridge where the 3M is activated carbon 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.
