How to clean an LG window air conditioner filter

To clean your LG window air conditioner filter, you need to remove, clean, and replace the filter without damaging it to ensure that your unit works properly.

Window air conditioners can cool down your space effectively, but they do need window access and require some maintenance, like cleaning the air filters regularly.

In order to clean your LG air conditioner filters, you need to prepare and remove, clean, dry and replace the filters.

Pros and cons of window air conditioning units

Window air conditioners were initially developed as a way for people to cool their homes without having to invest the vast amount of time and money needed for a central air system.

However, as time has gone by, technological advancements have made window air conditioners much more energy-efficient and aesthetically pleasing to look at.

The only real downside of these units is that you need a window to install this kind of air conditioner. Windows air conditioners do also require a bit of maintenance now and then, but not as frequently as portable air conditioners.

One of these regular maintenance activities includes cleaning the filters of your LG window air conditioner.

LG window air conditioners come in a variety of types and sizes, ranging from this 10000 BTU DUAL Inverter Smart Window Air Conditioner, which can cool rooms of up to 450 square feet, to this 22,000 BTU 230V Dual Inverter Window Air Conditioner with Wi-Fi Control, which can cool spaces of up to 1300 square feet.



However, regardless of the unit’s size, all window air conditioner filters need to be cleaned when the “clean filter” indicator light turns on.

To clean these filters properly, you need to complete three stages in the cleaning process. These stages are not complicated and should not take too long.

They are the preparation of the air conditioner and the removal of the air filter, the actual cleaning stage, and the drying and replacement stage.

Cleaning your filters is a necessary manual step to ensure that your LG window air conditioner continues to last and work effectively over the years.

Dirty air filters can block airflow to the rest of the unit, and this can cause many operational problems, which is why cleaning these filters should form part of your ongoing, regular maintenance routine.

Preparing and removing the air filters for your LG window air conditioner

Once you are ready to clean your air filters, you need to turn your LG window air conditioner off. To start with, remove the front panel of your LG window air conditioner.

This is true for units with grills, like this LW8016HR model and solid panel models as mentioned above.

For units that have a grey branded “LG” strip, like this LW1017ERSM, you only need to tug on this strip lightly to release the air filter.

While you are in this stage, you can also clean the outside of the unit using a sponge and some dishwashing liquid, and then rinse it off, being careful not to get the internal components of the unit wet. You can also straighten out the fins behind the filter, but these parts can be sharp, so it is important to be cautious.

Cleaning the air filters for your LG window air conditioner

Once you have removed the air filters from your LG window air conditioner unit, you actually start cleaning the filters. To do this, there are a few things you should keep in mind, such as:

  • Use lukewarm water, below 104 degrees Fahrenheit
  • Use a soft brush and gently scrub the filter under the running water to avoid damaging the air filter
  • You can use dishwashing liquid for stubborn dirt, but this could make your filters deteriorate quicker over time
  • If you notice any holes in or damage to your filters, you can purchase replacement filters, which will still prevent dirt and debris from entering your air conditioner

Drying and replacing the air filters for your LG window air conditioner

After the air filters of your window air conditioner have been sufficiently cleaned, you can remove any excess moisture by shaking the filter or drying it gently with a soft cloth, before letting it dry in an upright position, out of direct sunlight.

Once the air filter is completely dry, you can place it back inside the air conditioning unit and replace the front cover on the unit, if necessary.

You will then be able to switch your LG window air conditioner on again and press the decrease and increase temperature buttons simultaneously to remove the “clean filter” light from the display.
