Cleaning your Filters, the Number One Priority in Preparing for Summer

Summer is approaching and many of us are in the process of spring cleaning and preparing our homes and offices for the warm months ahead. While preparing the spaces we occupy everyday for the warm summer season, it is also necessary to properly prepare one of the most important items we use throughout the summer: the air conditioner!


There are a few simple, yet invaluable steps to ensuring that your air conditioner keeps the air cool and clean all summer long. Let’s discuss one of the most important and often overlooked steps in preparing your air conditioner for summer, which is cleaning the filters. Lucky for us, the LG 1 Way Cassette and Moving Panel (Window) type air conditioner unit filters are so easy to clean, anyone can do it!

What’s in a Filter?

Air conditioners play an important role in keeping us comfortable and keeping the air in our homes and offices clean during the summer. When we look to turn on our air conditioners at the beginning of summer, cleaning the filters should be one of the first things that come to mind. Clogged or broken filters block airflow and cause added strain on your air conditioner that negatively impacts the unit’s performance and efficiency. Blocked airflow will not only hinder efficiency but also prevent the air conditioner from properly dispersing cool air throughout your home or office. Dust or dirt in the filter will also cause bacteria and allergens to be distributed into the air, which can be harmful to your health. To keep your air conditioner running strong all summer long, we recommend that you clean the filters once a month during the peak summer months.

Cleaning your Filters the Easy Way

We have prepared a short list of pointers to show you how it’s done

1. First, turn off the mains supply to the air conditioner for safety
2. Remove the outer casing from the air conditioner and remove the filters
3. Use a soft brush to carefully brush dust and grime from the filters
4. Fill a basin or tub with a solution of water and a neutral detergent and wash the filters in the solution to disinfect from bacteria and allergens (don’t use water over 40°C)
5. Rinse the filters thoroughly with water to remove all dirt and detergent
6. Set the filters out to dry completely, preferably outside just out of direct sunlight. Water remaining on the filters can cause damage to the air conditioner.
7. Return the filters to their original location being sure to fasten the cover securely


Cleaning air conditioner filters is a simple yet necessary step to keep your air conditioner running efficiently and ensure that the air in your home or office is cool and clean. We recommend performing this simple task regularly to maintain top performance in your air conditioner and to maintain your health.
