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.
