Home Studio Water Filter Dispenser vs Culligan 12-Cup Water Filter Pitcher with ZeroWater Technology: which is safer?

Where these two actually differ

• We flag Bacterial biofilm and microbial growth, Filter housing degradation and microplastic generation and Improper filter installation and bypass leakage on the LifeStraw and not on the ZeroWater.
• We flag Bacterial growth in reservoir if filter unmaintained or water stored too long, Filter cartridge degradation and particle escape if overfilled or misseated and Ion-exchange resin saturation without visible warning on the ZeroWater and not on the LifeStraw.
• The LifeStraw is activated coconut carbon + plastic housing where the ZeroWater is Activated carbon and ion-exchange resin filter media, 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.
