Where these two actually differ

  • We flag Bacterial growth in unmaintained filter housing and Activated carbon dust or fines ingestion on the LG and not on the Whirlpool.
  • We flag Bacterial growth in filter media (biofilm accumulation), Carbon dust or particle release into water and Filter housing seal or valve failure on the Whirlpool and not on the LG.
  • The LG is activated carbon, polypropylene housing where the Whirlpool is Activated carbon and polypropylene (typical refrigerator 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.

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 →
