The LG refrigerator air filter can be changed by finding its location in the fridge, removing the old filter from the filter cover, and placing the new air filter in its place. It is essential to change your air filter when the LED control panel gives a ‘Replace Filter’ signal, or it has been 6 months since you last changed it. 

We promise that following this article will make changing your LG refrigerator air filter much easier. So, keep scrolling to read detailed instructions.  


Purpose Of An Air Filter In A Refrigerator

A refrigerator is where you preserve all your processed and unprocessed food. The LG refrigerator air filter inside your fridge compartment is meant to soak in all the foul odors and circulate clean air. As a result, it keeps your refrigerator’s internal environment fresh and healthy. 




The carbon-based mesh-like air filter absorbs in-borne circulating particles, moisture, and volatile molecules. Thus, the food remains healthy, the compartment remains fresh, and the environment becomes unsuitable for the growth of microorganisms. 


There are two settings for the air filter in your LG refrigerator, which can be activated in the control panel as and when needed:


  • Auto-mode: The filter will cycle on and off as needed. (10 mins. On and 110 mins. Off). 
  • Power-mode: The filter will cycle on and off for 4 hours continuously (10 min. on and 5 mins off) and then automatically switch back to auto mode. 


Note that the power mode is more electricity-consuming than the auto mode. Press the ‘Air Filter Button’ once for auto mode and twice for power mode

Importance of Regular Replacement of Air Filters

You must keep your air filter life in mind after purchasing a refrigerator. Timely replacement of the air filters helps you maintain optimal performance and air quality inside your fridge. To understand its importance, look at the following downsides of not replacing your air filter: 


  • The clogged air filter will become a perfect breeding place for microorganisms leading to bacterial contamination. 
  • The refrigerator machinery would have to work harder to pull and circulate air, leading to higher energy consumption. Thus, you can expect higher electricity bills. 
  • The refrigerator will be filled with unpleasant smells every time you open it due to poor circulating air quality. 
  • The food kept inside may also start smelling bad and rot quickly. 


Remember, it is recommended to replace your LG refrigerator fresh air filter every 6 months (twice a year) or when the LED control panel lights up the ‘Replace Filter Alert Icon,’ whichever is earlier. So, mark your calendars or set reminders for six months. 




The refrigerator compartment smell and increased power bills will also give you a hint. Pay attention to the signs, and you will know when it's time to purchase a new compatible air filter for replacement.


Common Air Filter Locations

Different refrigerator manufacturing engineers design fridge models in different ways. The most suitable location for an air filter is the fridge compartment where the food is kept. It is placed where it can give the maximum benefit and work most efficiently, as air circulation should not be hindered. 


The most common air filter locations are in the grille at the bottom of the refrigerator, on the rear wall of the refrigerator, or at the inner ceiling of the fridge compartment. You must check your refrigerator model number and user manual to know exactly where to find the air filter.
