Overview
The Pureline PL-1100 is a replacement refrigerator water filter built to fit the LG LFX25974ST, WQA certified and sold as a single cartridge. It uses an advanced active coconut carbon block filtration media.
Coconut-shell carbon block media is a denser format than granular carbon, generally associated with more contact time between water and filter as it passes through. The stated compatibility narrows this to the LG LFX25974ST specifically rather than a universal fit across LG's lineup.

Performance notes
Coconut carbon block filtration compresses the carbon into a solid block rather than loose granules, generally slowing flow slightly in exchange for more thorough contact between water and media.
