Where these two actually differ
- We flag Bacterial growth in filter housing, Activated carbon dust in water and Rubber seal degradation on the Soma and not on the TAPP Water.
- We flag Bacterial colonization on filter media, Metal component corrosion or oxidation and Inadequate contaminant reduction claims on the TAPP Water and not on the Soma.
- The Soma is borosilicate glass pitcher, activated carbon filter cartridge where the TAPP Water is Activated carbon filter media with metal/plastic housing, 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.
