Keeping your refrigerator’s water clean, fresh, and great-tasting is essential—and replacing your LG water filter shouldn’t be complicated. The LG ADQ73613409 Refrigerator Water Filter Assembly ensures your fridge continues to deliver high-quality, purified water by reducing impurities such as chlorine, sediment, and unwanted taste or odor.

This genuine OEM filter is engineered by LG to perform exactly like the original, maintaining proper water flow and filtration performance so your family always gets crisp, refreshing water straight from the fridge.

Whether your fridge is showing a “Replace Filter” alert, the water tastes off, or the dispenser flow has slowed, the ADQ73613409 is the correct replacement to restore clean water with optimal filtration.

How to Identify If the ADQ73613409 Filter Is Compatible with Your LG Refrigerator

Before purchasing a replacement filter, it’s important to verify compatibility with your specific refrigerator model. Many LG filters look similar, but each part number is designed for a particular series.

Here’s how to find your refrigerator’s model number:

1. Inside the Refrigerator Wall

Open the fresh-food compartment and look for a label on the side wall or behind the crisper drawer.

2. User Manual or Original Packaging

Your refrigerator’s instruction guide or box will list the full model number.

3. LG Settings Menu (for smart models)

If your fridge is Wi-Fi enabled, navigate to the settings screen to view your model information.

Once you’ve located your model number (e.g., LFXS30766S, LMXS28626D, LSXS26366S), use it to confirm that the ADQ73613409 is the correct replacement filter for your refrigerator.

How to Replace the ADQ73613409 Water Filter

Installing your new LG water filter only takes a minute—no tools required. For most compatible models, follow these quick steps:

1. Open the refrigerator door and locate the filter housing, usually positioned in the upper left corner.
2. Press the release button or pull the old filter downward/outward, depending on your model.
3. Align the new filter with the housing and insert it firmly until it clicks into place.
4. Run approximately 2–3 gallons of water through the dispenser to flush out any air or carbon residue.
5. Reset the “Replace Filter” indicator using your refrigerator’s control panel.

Once installed, your fridge will immediately return to delivering clean, great-tasting water and ice.
