How to clean aircon filter from a centralized aircon unit?


Step 1) Determine the air filter location


With central aircon units, the filter typically resides near the cold air return. However, you may also have filters behind your return vents, which will be scattered throughout the house.


Step 2) Turn off your aircon unit

Whenever you perform any type of servicing on your aircon unit, it’s a good idea to turn the unit off. This will protect it and you.


Step 3) Remove the air filter and vacuum it


Typically, there will be a good amount of dust build-up onto the filter. You can remove most of it using a vacuum with a bristled attachment. Do this for all of your central aircon filters, including those hiding behind the returns. And make sure you vacuum either side of your filter as well.


Step 4) Soak the filter in a 50/50 mixture of water and vinegar

If your filter is water-friendly, soak it in a mixture of equal parts water and vinegar for about an hour. Before reinstalling the filter, let it dry completely.

If you don’t have a basin large enough to hold your aircon unit filter, use a hose instead. Make sure you set the pressure very low as anything too intense will easily rip through the filter.

This panel will be held in place by screws, pressure, or some simple plastic clips. Once you remove the panel, it’ll be impossible to miss the filter.


Step 3) Vacuum and thoroughly wash your window aircon unit filter


As always, read your aircon unit’s instruction manual to make sure water won’t harm the filter. If the filter smells a little musty, that may be an indication of moisture problems inside that would require a more thorough cleaning of the entire aircon unit.
