Where these two actually differ
- We flag Bacterial growth in filter housing, Carbon fine particles in water and Cartridge bypass due to improper installation 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 and/or ion-exchange resin filter media 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 →
