Where these two actually differ
- We flag Undisclosed filter media composition, Bacterial growth if maintenance neglected, Cartridge/filter media shedding into water and PFAS in filter media or housing adhesives on the Sigma and not on the B+W.
- The B+W is Optical glass lens with multi-coated optical surfaces where the Sigma is Unspecified filter media, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
- We are less certain about the Sigma grade, at 25% confidence against 82%, because it discloses less.
Both products run through the same public rubric, which covers 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 →
