Filtered Water Bottle with Nanofiber Fast Flow Filter Media vs Sustainable Pitcher: which is safer?

Where these two actually differ

• We flag Microplastics from filter media degradation, Bacterial growth in filter housing if unmaintained, Housing material leachables (bottle body) and Filter media composition and toxicity (undisclosed) on the and not on the Soma.
• We flag Bacterial growth in filter housing, Activated carbon dust in water and Rubber seal degradation on the Soma and not on the .
• The is Nanofiber filter media (composition unspecified) where the Soma is borosilicate glass pitcher, activated carbon filter cartridge, which is most of the difference in these two grades.
• The gap is 40 points, wide enough that this is not a close call, and the Soma is the one to buy.
• We are less certain about the grade, at 45% confidence against 72%, because it discloses less.
