Where these two actually differ

  • We flag Bacterial growth in filter media on the Kirkland 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 Kirkland.
  • The Kirkland is BPA-free plastic pitcher with activated carbon filter 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.
