Frequently Asked Questions

What LG refrigerator models is the Tier1 LT120F replacement air filter compatible with?

The Tier1 LT120F comparable replacement is designed to fit LG and Kenmore French door refrigerators that use the original LG LT120F air filter, including Kenmore Elite models 795 series. It is a direct drop-in replacement for the OEM LG LT120F (also known as ADQ73214402, ADQ73214404, and ADQ73334008). Always verify your refrigerator's model number before ordering to ensure proper fitment inside the designated air filter compartment.

How often should I replace the Tier1 LT120F refrigerator air filter?

The Tier1 LT120F replacement air filter should be changed every 6 months for optimal odor and air quality performance inside your LG or Kenmore refrigerator. Unlike water filters measured in gallons, air filter life is based strictly on time because it continuously works to neutralize airborne odors from food. Many LG refrigerators include a built-in air filter indicator light that will signal when the 6-month cycle is complete.

What does the Tier1 LT120F air filter actually remove from my refrigerator?

The Tier1 LT120F uses an activated carbon media specifically formulated to absorb and neutralize strong food odors, ethylene gas, and airborne contaminants circulating inside the fresh food compartment. By reducing ethylene gas, it helps slow the ripening process of fruits and vegetables, keeping produce fresher longer. It does not filter water — it is a dedicated air-purifying cartridge for the refrigerator interior only.

How do I install and reset the air filter indicator after replacing the LT120F?

Installation is tool-free: open the air filter cover located on the rear interior wall of your LG refrigerator, remove the old cartridge, and snap the new Tier1 LT120F into place. After installation, press and hold the "Air Filter" reset button on your refrigerator's control panel for 3–5 seconds until the indicator light turns off. This ensures your fridge accurately tracks the next 6-month replacement cycle.

Is the Tier1 LT120F replacement as effective as the genuine LG OEM air filter?

Yes, the Tier1 LT120F comparable replacement is engineered to meet or exceed the performance specifications of the original LG LT120F air filter at a significantly lower cost. It uses premium activated carbon to deliver the same odor-reduction and freshness benefits, and fits seamlessly into the OEM housing without modification. Tier1 manufactures its filters to strict quality standards, offering a reliable, budget-friendly alternative to the branded LG cartridge.
