Where these two actually differ
- We flag Activated carbon dust or particle shedding, Bacterial or biofilm growth in filter housing and PFAS removal performance (non-PFAS hazard context) on the Culligan 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 Culligan.
- The Culligan is Activated carbon filter with polypropylene 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 →
