To clean your Fujitsu air conditioner filter, start by turning the unit off and isolating the power. Open the front panel of the indoor unit, slide the filters out, and clean them using a vacuum or warm, soapy water. Make sure the filters are completely dry before reinstalling them to help prevent mould and keep the system running efficiently. For specialised filters, such as ion deodorising or dust-collecting types, follow the manufacturer’s specific instructions, but the general process of gentle cleaning and thorough drying applies to most filters.
Fujitsu remains one of the top energy-efficient and reliable air conditioner brands that many Australian consumers trust. However, your system won’t be working at its best if it’s clogged. To keep it efficient enough to maintain good air quality and save on energy bills, you’ll have to keep it clean.
How to Clean Fujitsu Air Conditioner
So, how do you clean your Fujitsu air conditioner? The first step is to check your owner’s manual; not only will it detail how to clean and maintain your system, but it will also show how to access and remove the filters and other removable components from your indoor unit.

General Cleaning
Depending on the type of AC, there are various ways to clean it. In general, you should clean the intake grille, air filter, dust collection unit and other user-maintainable parts of any dirt or debris. As to how frequent, the rule is: the more you use it, the more often you should clean them. Once a month is a good standard for those who use their air conditioner daily.
For Fujitsu Wall-Mounted Split Systems
Basic cleaning for your wall-mounted split system only takes a few minutes, and is straightforward.
- Carefully remove the intake grille and use a damp cloth to wipe it. You can also gently vacuum along the grooves.
- Remove the air filters and wash them with mild detergent and warm water or use a vacuum cleaner.
- Remove the dust collection unit and soak for a few minutes in a bucket of warm water mixed with a teaspoon of mild detergent. Rinse with warm water.
- Vacuum the AC system’s interior and wipe it down using a damp cloth.
- Reinsert the dust collection unit, filters and grille. Make sure all components are thoroughly dry, and give the exterior a final wipe.
Note that this brief guide only covers what to do for routine cleaning. If you haven’t cleaned your system in a while and are seeing defects or hearing odd noises, it may be best to have a professional AC technician inspect your unit.
When to Call Professionals
While routine cleaning can be doable, dust, mould, and other pollutants can accumulate inside the air conditioner faster than usual if you use your air conditioner frequently and live in a dusty or humid environment. Water leakage may also be possible if the drainage pipe gets blocked by dirt and gunk. In such instances, regular professional electrician service and cleaning would be a better option.
