Refrigerator Water Filter 744000200
Lower concern. Carbon/media filters rarely contain PFAS.
Liebherr water filters use activated carbon and filter media, materials with lower inherent PFAS risk. No brand disclosure on PFAS, but filter category suggests lower concern than coated cookware or treated textiles.

The full breakdown
What it's made of and why it matters
The Liebherr 744000200 uses activated carbon as its primary filtration medium, a porous material that adsorbs dissolved chemicals, chlorine, and some organic compounds through surface attraction rather than mechanical blocking. Activated carbon does not leach harmful substances into water under normal refrigerator conditions (cold, low pressure) because it operates passively and is inert when wet. The filter housing is typically plastic (polypropylene or similar food-grade polymer), which remains stable at refrigerator temperatures and does not shed particles into drinking water under standard use.
The brand's record and disclosure
Liebherr, a German appliance manufacturer, does not publish detailed safety disclosures or third-party certifications specific to this filter model in publicly available sources. The company has no documented recalls or safety controversies linked to this filter cartridge. Liebherr does not explicitly market PFAS-free claims, but activated carbon filters of this type are not known to contain PFAS as an ingredient or byproduct.
How it compares in its category
Refrigerator filters are among the lowest-risk filtration products because they operate at cold temperatures and low flow rates, eliminating thermal leaching risks that affect pitcher or faucet filters. The Liebherr 744000200 is a standard OEM replacement; it performs similarly to other carbon cartridges from major brands (LG, Samsung, Electrolux) with no documented performance or safety advantage. Aftermarket generics may pose slightly higher bacterial contamination risk if manufacturing quality control is inconsistent, though Liebherr OEM filters benefit from the brand's supply chain oversight.
If you buy it
Replace this filter every 6 months or according to your refrigerator's indicator light; exhausted carbon loses adsorption capacity and does not prevent bacterial biofilm growth inside the cartridge. Flush the filter housing briefly when installing a new cartridge to remove any loose carbon particles. Store unopened filters in a cool, dry place; once installed, the filter should be exposed to water continuously (do not leave the refrigerator unused for extended periods without replacing the filter). If water tastes musty or chlorine smell returns before 6 months, replace the filter early.
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 contamination in exhausted or stagnant filters
Activated carbon can support biofilm growth if not replaced regularly or if refrigerator use is interrupted; risk is low with proper 6-month replacement but increases significantly if filters are left in place beyond recommended lifespan.
Loose activated carbon particles in water
New filters may shed fine carbon dust during initial use; flushing the system when installing reduces this risk. No health hazard from ingested carbon particles, but reduces water clarity and taste acceptance.
Housing material leachates (polypropylene)
Food-grade polypropylene used in filter housings is stable at refrigerator temperatures and is not documented to leach BPA, phthalates, or other endocrine disruptors under cold, low-pressure conditions. No recalls or contamination incidents reported for this product.
Incomplete contaminant removal due to filter exhaustion
This is a functional safety issue, not a toxic hazard: expired filters do not actively harm water but fail to remove chlorine taste, some pesticide residues, or volatile organic compounds, leaving users exposed to contaminants the filter was intended to block.
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.
