Waterdrop LT1000PC Refrigerator Water Filter ADQ747935
Lower concern for PFAS, but LG makes no public commitment; verify independently if precaution matters to you.
The LT1000PC uses standard activated carbon and ion-exchange resin filtration, materials not inherently associated with PFAS. LG makes no public claims about PFAS-free status or testing for this filter.

What Waterdrop LT1000PC Filter ADQ747935 is made of, ingredients and materials
The LT1000PC uses activated carbon and ion-exchange resin as its filtration media, both mature, non-toxic materials with long safety records in drinking water applications. Activated carbon adsorbs chlorine, taste, and odor compounds; ion-exchange resin removes hardness ions (calcium, magnesium). Neither material leaches significant chemicals into water under normal refrigerator conditions (low temperature, low pressure, short contact time). The filter housing is typically polypropylene, a durable plastic with minimal leaching risk when not heated.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Bacterial colonization if filter not replaced on schedule
Saturated carbon and resin media can support biofilm growth if water stagnates or filter contact time lengthens. Regular 6-month replacement and normal refrigerator flow rates minimize this; immobile filters or extended storage increase risk.
Incomplete contaminant removal if filter is counterfeit or damaged
Fake or defective filters may not contain true activated carbon or resin, reducing contaminant capture. Buy from reputable sources and verify packaging authenticity. This is a performance, not a direct toxicity, hazard.
Carbon dust ingestion if filter is not primed
First water from a new carbon filter may contain small amounts of loose carbon particles. Run water through the filter for 2-3 minutes before use to flush media; standard practice that eliminates this minor nuisance hazard.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Polypropylene housing leaching (low temperature, low risk)
The filter housing is food-grade polypropylene, which does not leach BPA or phthalates under refrigerator conditions. No recalls or field reports document leaching from LG or compatible filters of this type.
How is this PFAS grade calculated?
The brand's record and disclosure
LG does not publish detailed material safety data or third-party certifications specifically for this filter model. The company has no known history of recalls or contamination incidents tied to LG refrigerator filters. Like most appliance manufacturers, LG does not make public commitments on PFAS elimination in filter media, a common industry silence that reflects the absence of regulatory pressure on these components. NSF or WQA certification data for this specific model is not widely published; buyers should verify filter certification on the product documentation if independent standards are important.
How it compares in its category
Aftermarket refrigerator filters (like Waterdrop, EveryDrop, Whirlpool-branded alternatives) all use similar carbon and resin technology, so this filter sits squarely in the mainstream safety profile for the category. No replacement filter subtype has demonstrated superior or inferior safety in published comparisons. Genuine LG filters and compatible third-party models carry equivalent material risk profiles; the main difference is cost and availability, not chemistry.
If you buy it
Replace the filter every 6 months or per manufacturer guidance (typically 200-300 gallons); a clogged filter loses effectiveness and may harbor bacterial growth if water sits too long in the cartridge. Do not attempt to clean or reuse the filter; carbon saturation is irreversible. Store filters in a dry place before installation. If water odor or taste changes noticeably after replacement, verify the cartridge is seated correctly or check for a defective batch, though this is rare.
