Air purifiers play a vital role in maintaining the quality of air in the indoor environment. A key component of an air purifier is the filter, which helps to capture and remove particles and pollutants from the air. So, do you know how to clean the filter of the LG air purifier? Follow us for a step-by-step guide on how to clean it.


Understanding LG air purifier filters

LG offers a range of air purifiers that use different types of filters, including pre-filters, HEPA filters and activated carbon filters. Pre-filters act as a first line of defence, capturing larger particles such as dust and pet hair, while HEPA filters are designed to remove smaller particles such as pollen, mould spores and bacteria. Activated carbon filters help neutralise odours and capture volatile organic compounds (VOCs).


Regular Maintenance of LG Air Purifier Filters

Proper maintenance of the filter is essential to ensure that the air purifier operates effectively. Below are the steps for cleaning the LG Air Purifier filter:


1. Preparing the Filter for Cleaning Before you start cleaning, switch off the air purifier and unplug it for safety reasons. Then, remove the filter cover to gain access to the filter. 2. Cleaning the pre-filter The pre-filter can be cleaned by gently sucking up dust and larger particles with a vacuum cleaner or soft brush. Make sure to remove all visible debris from the pre-filter. 3. Cleaning the HEPA and activated carbon filters Always refer to the specific instructions provided by LG when cleaning the HEPA and activated carbon filters. Different models may have different cleaning methods. Some filters can be cleaned, others need to be replaced. For detailed cleaning instructions, please refer to the user manual or visit the official LG website.


Drying the Filter

After cleaning the filter, it must be allowed to dry completely before reinstallation. Filters can be air-dried in a cool, ventilated area. Avoid exposing the filter to direct sunlight or using a heat source to speed up the drying process.


Replacing the Filter

Monitor the filter's condition periodically to determine if it needs to be replaced. Follow the manufacturer's recommendations for filter life and replacement intervals. If the filter is damaged, heavily soiled, or no longer effective after cleaning, replace it with a new filter.


Tips for Extending the Life of Your LG Air Purifier Filter

To extend the life of your LG Air Purifier filter and ensure optimal performance, consider the following tips:

1. Clean the pre-filter regularly to prevent larger particles from clogging the HEPA and activated carbon filters. 2. Place the air purifier in a well-ventilated area to ensure proper airflow and filtration. 3. 3. Avoid exposing the filter to humid environments as this can lead to mould or bacteria growth. 4. Monitor the air quality of your surroundings and adjust the air cleaner settings accordingly. This will reduce the workload on the filter. 5. Perform regular cleaning according to the manufacturer's recommendations to prevent excessive build-up of contaminants and maintain efficient filtration.



Proper LG Air Purifier filter maintenance is essential to ensure clean and healthy indoor air. Regularly cleaning and replacing the filter when necessary will help maintain the optimal performance and longevity of your air purifier. By following the cleaning guidelines provided by LG and mentioned by us, you can enjoy cleaner air in your living space.
