LG air conditioners come with a built-in filter that helps keep your home cool and comfortable. However, over time, the filter may become dirty and need to be cleaned. Here are some tips on how to reset the air conditioner clean filter:

  1. Open the air conditioner’s main door and remove the filters from all of the units in the room.
  2. Disconnect all of the cords from each unit in the room.
  3. Pour a pot of water onto a cloth and place it over one of the filters on each unit in the room.
  4. Use a plunger to push down on one of the filters until it pops out from underneath (be sure not to damage or remove any parts of the filter).
  5. Place another cloth over top of both filters and replace them back into their places on each unit in the room.
  6. Close up all of the air conditioner’s doors and turn on your AC unit.
