LG ADQ73693903 Original Dual Fridge Filter Upgrade Kit (With 5 Micron Sediment)

Upgrade your refrigerator’s water and ice system with the Dual Fridge Filter—designed for households that value both water quality and appliance protection. This two-stage filtration setup is engineered to fit into your fridge’s water feed line and includes:

Stage 1: Inline Sediment Pre-Filter
Installed first in the water supply line, this filter captures visible particles such as rust, sand, dirt, and large debris. Removing these coarse contaminants first helps protect your second-stage cartridge and prolongs the life of your fridge's internal water/ice path.

Stage 2: External LG Fridge Water/Ice Cartridge (ADQ73693903)
The second stage replaces the existing inline fridge cartridge and is dedicated to improving taste and odour while reducing fine sediments and chlorine. Installed externally in the fridge water line, it ensures the water and ice dispensed are of higher clarity and flavour.

Together, the two filters form a robust chain: first removing coarse solids, then polishing the water for taste and protection. Installation is straightforward with push-fit or quick-connect fittings, and cartridge replacement is simplified.

Note: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
