Lg Appliances Adq74813401 Water Filter - Filters Screens & Driers
Lower concern water filter, but LG provides no PFAS transparency.
LG refrigerator replacement filters typically use activated carbon and polypropylene, materials with lower inherent PFAS risk. LG does not publicly disclose PFAS status or hold relevant certifications.

No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
This filter uses activated carbon as the primary media, supported by polypropylene (PP) housing and filter substrate. Activated carbon is inert and does not leach into water under normal use conditions. Polypropylene is a food-contact safe plastic at room temperature and does not release BPA or phthalates in cold-water filtration.
The brand's record and disclosure
LG does not publicly disclose PFAS removal claims or third-party testing certifications for this specific model. The company maintains no visible transparency page for water filter safety specifications. No recalls or contamination incidents have been publicly documented for this filter line.
How it compares in its category
Activated carbon filters are a mainstream, low-risk category standard. This LG model lacks NSF certification or independent verification, which is common for OEM replacement filters but places it behind certified aftermarket alternatives like Aqua-Pure or EveryDrop. The absence of transparency is a relative weakness, not a safety failure.
If you buy it
Replace cartridges every 6 months or per manufacturer guidance to prevent bacterial biofilm growth inside the housing. Do not expose the filter housing to heat or direct sunlight. Allow cold water only to pass through (no hot-water bypass). Clean the housing threads and seals quarterly to avoid mold at connection points.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Bacterial growth if unmaintained
Activated carbon filters can harbor bacterial biofilm if cartridges are not replaced on schedule or housing is left stagnant. Regular replacement (every 6 months) and flushing mitigate this risk substantially.
Polypropylene housing leachables
Polypropylene is chemically inert in cold water and poses no documented leaching risk at room temperature. No BPA, phthalates, or other endocrine disruptors are released under normal filtration conditions.
Activated carbon dust or particles
New carbon filters may release fine carbon particles in the first flush cycle. Running water through the filter for 2-3 minutes before use eliminates this; a single-use flushing is standard practice.
Seal degradation over time
Rubber or silicone gaskets in the cartridge connection can degrade after 12-18 months or repeated thermal cycles if the filter is left in warm environments. Inspect seals before installation and replace cartridges on schedule.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
