Where these two actually differ
- We flag Bacterial biofilm growth in filter media and Filter media degradation or contaminant breakthrough on the Kohler and not on the Showerhead Filter.
- We flag ABS plastic thermal degradation, Bacterial/fungal growth in filter media, Brass/copper leaching (if brass internals used) and Filter media particulate shedding on the Showerhead Filter and not on the Kohler.
- The Kohler is Activated carbon filter media, plastic housing where the Showerhead Filter is ABS plastic head, stainless steel or brass internals, activated carbon 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.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
