Glacier Fresh Replacement for LT1000P, ADQ747935 Refrigerator Water Filter with Air Filter, 3-Pack

No, most refrigerator air filters—especially those containing activated carbon—cannot be washed or reused because water will impair their deodorizing ability.

The Glacierfresh LT1000P air filter is an activated carbon-based filter that can adsorb ethylene gas, seafood odors, food odors such as cheese, and musty odors, helping to preserve fruits and vegetables.

A sealed, unused refrigerator air filter has a long shelf life, typically 2 to 3 years if stored properly. While they don't "expire" like food, the activated carbon within them will gradually lose its effectiveness over time, especially after 3 to 5 years of use.

Yes, refrigerator air filters can remove musty odors and also absorb other common food odors. These filters use activated carbon to neutralize particles, bacteria, and mold spores that produce unpleasant odors during air circulation.

f your fridge uses the LT1000P water filter, it almost certainly uses the LT120F air filter as well — they're paired in the same generation of LG French door and side-by-side models. The GFA-002 air filter in this pack replaces LT120F, ADQ73214404, ADQ73334008, ADQ73214402, ADQ73214403, and Kenmore 469918 / 46-9918 / 9918. You can also check the label on your current installed air filter — it's typically located in a small compartment at the back of the fridge interior.

The air filter is located in a small housing at the back wall of the refrigerator compartment, usually near the top. To replace it: open the cover by pressing the tab or sliding it open, pull out the old filter cartridge, insert the new GFA-002 filter, and close the cover. No tools needed — it takes about 30 seconds. Unlike the water filter, there's no reset button for the air filter on most models; just track the date and replace every 3–6 months.

Almost always yes. Since both filters need replacing on roughly the same schedule (every 6 months), buying them together means one order, one delivery, and one reminder — instead of managing two separate purchases. The combo pack also saves money compared to buying each filter individually, and you'll always have both on hand when it's time to replace. It's the most convenient and cost-effective way to stay on top of both filters at once.

Yes, and it's one of the most overlooked fridge maintenance items. The LT120F air filter (included in this pack) works like a deodorizer inside your fridge — it uses activated carbon to absorb ethylene gas and odors produced by food, which helps keep food fresher longer and prevents cross-contamination of smells between foods. If your fridge smells like last night's leftovers or your produce is wilting faster than expected, a fresh air filter is often the fix. Replace it every 3–6 months alongside your water filter.
