Where these two actually differ
- We flag Bacterial growth in filter housing and Filter bypass or incomplete sealing 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 filter media, plastic 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 →
