LG 200 Gallon Refrigerator Water Filter
Lower PFAS concern; activated-carbon filters aren't a typical PFAS source, but LG doesn't publicly disclose PFAS testing.
This filter cartridge relies on activated carbon media to remove contaminants, a material class not inherently associated with PFAS contamination. LG doesn't publicly make PFAS-free claims or provide verification.

Lab data
No public lab test
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Bacterial growth in filter media
Activated-carbon filters can support microbial biofilm if not replaced on schedule or if the refrigerator is not maintained cold enough. This is a usage issue, not a material defect, but remains the primary contamination risk for this product class.
Loose carbon particulate in water
New or poorly installed filters may shed fines of activated carbon into water during initial use; this is harmless but undesirable. Rinsing before use and proper seating minimize this.
Taste or odor rebound
Beyond 200 gallons or 6 months, carbon saturation can allow chlorine and taste compounds to break through; this signals replacement need but is not a safety hazard per se.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Plastic housing leachables
LG filter housings are food-grade and designed for cold-water contact. No reports of BPA, phthalates, or other plastic leachates from this product line at normal refrigerator temperatures.
Heavy metals
Coconut-shell activated carbon does not leach metals into water. The filter may trap trace metals from source water, but this is the intended function and poses no risk to users.

What it's made of and why it matters
LG 200 Gallon filters use activated coconut-shell carbon as the primary filtration media, a well-established material for chlorine, taste, and odor removal in potable water. Coconut-shell carbon does not leach heavy metals or synthetic compounds into water under normal refrigerator use conditions (cold water, low pressure). The filter housing is typically food-grade plastic designed to withstand cold temperatures and brief contact with treated water.
The brand's record and disclosure
LG does not publicly disclose third-party testing data or PFAS screening results for this filter line, which is consistent with most refrigerator-filter manufacturers. The product carries NSF certification (where applicable models are listed), indicating basic microbial and chemical contaminant reduction standards, though NSF does not independently test PFAS removal. No recalls or safety controversies specific to LG refrigerator filters are on record.
How it compares in its category
LG filters are mid-range in the refrigerator-filter market and perform comparably to Whirlpool, Samsung, and generic carbon filters in chlorine/taste reduction. Unlike pitcher filters or under-sink cartridges, refrigerator filters see minimal user contact and lower flow rates, reducing leaching risk. The 200-gallon capacity is standard and reflects typical household use before bacterial biofilm risk rises.
If you buy it
Replace every 6 months or at 200 gallons, whichever comes first; stagnant filters can harbor bacteria if left in place longer. Do not expose the filter to heat or direct sunlight before installation. Flush the first few pitchers of water after installation to clear loose carbon dust. Ensure the filter is fully seated in the refrigerator housing to prevent bypass.
