How often should I replace my LG refrigerator air filter?

LG recommends every 6 months. Some newer models have a filter status indicator that turns red when it's time. If you cook with strong-smelling ingredients often, you might want to swap it closer to every 4 months.

Will this fit my specific LG or Kenmore refrigerator?

It's designed to replace the LG LT120F and fits Kenmore Elite models using part numbers 469918, 9918, ADQ73214402, ADQ73214404, and ADQ73334008. Check your current filter's part number to confirm compatibility.

Is there a noticeable difference between this and the original LG filter?

Both use activated carbon to absorb odors, and most users report identical performance. The main difference is price. You'll typically save 30-50% compared to the OEM version, especially when buying the 3-pack. --- *As an Amazon Associate, PeekBuys earns from qualifying purchases.

Nobody wants to open their fridge and get hit with a wave of stale odors. LG refrigerators use an internal air filter to neutralize smells, but most people forget to replace it every 6 months like the manual recommends. A compatible replacement filter lets you swap it out on schedule without paying premium OEM prices, and buying a 3-pack means you're covered for 18 months.

Who Should Buy This?

This is for anyone with an LG or Kenmore Elite refrigerator who wants to keep their fridge smelling clean without overpaying for name-brand filters. If you've noticed lingering food odors even after cleaning, a worn-out air filter is almost always the culprit. It's also a solid pick for people who like to buy in bulk so they don't have to remember to reorder every few months.

Buying Tip

Before ordering, pull out your current air filter and check the part number printed on it. The most common LG number is LT120F, but confirming the exact model (ADQ73214402, ADQ73214404, or ADQ73334008) ensures you get a perfect fit with no surprises.
