What many people don’t realise is that air conditioner need regular cleaning. (And no, that doesn’t just mean giving the outside a once-over!)

To keep your air conditioner clean and working optimally, you need to open it up and clean your air conditioner’s filter on the inside.

Cleaning your air con filters regularly will go a long way to maximise your AC’s lifespan. With these easy tips, you can keep your air conditioner clean and working efficiently for the long haul.

For a ducted air conditioning system, the air conditioning filter is usually located at the Return Air Grill installed in your home. For a split system air conditioning system, the air conditioning filter is usually located at the front of the indoor air conditioning unit.

Step-by-Step Guide to Cleaning Your AC Filter

Step 1: Turn your air conditioning off

Before you get started, make sure your air conditioning unit is turned off.

For a split system air conditioner, this means ensuring the air conditioning unit is turned off at wall. You don’t want to be taking apart an appliance while the power is on.

Step 2: Read your instruction manual

Your air conditioner’s operation manual should always be your first point of reference. If you can’t find yours, you may be able to download a copy from the manufacturer’s website. If you have a Dakin air conditioner, you can find an online copy of your instruction manual at the Daikin Australia website.

For a split system air conditioner, open the unit’s front panel to remove the filter.

Opening your air conditioner’s front panel will give you access to the air filters. You may be able to spot clean a few surfaces or nooks that you can clean while it’s open.

Instructions on how to clean you Daikin split system air conditioner can be found at Daikin Australia’s YouTube Channel.

For a ducted air conditioning system, open the Return Air Grill to remove the filter.

Step 3: Remove air filters from the air conditioning unit

Air filters should lift and remove easily from the air conditioning unit. Be careful not to be too forceful. Also, take note of how they look in place. This will come in handy when you’re ready to put the clean air filters in later.

Use a brush or vacuum to remove excess dust from the filter

Take the air filters outside for a good shake or brush down. Vacuum with a dusting brush head, if you’ve got one. This should remove all the dry dust and particles.


Step 4: Wash the filters thoroughly in water

If your air filters are grimy, you can handwash them with some warm water and mild detergent. Rinse them clean so there’s no residue left on the filters.

Step 5: Allow the filters to dry completely

The last thing you want is damp air filters. Make sure they’re totally dry, perhaps by leaving them to dry in outside in the sun, before you pop them back into the air conditioning unit.

How to Clean AC Filter

Cleaning your AC filter is a simple task that can be done with basic household supplies. Here’s a step-by-step guide:
Turn Off the Power: Before starting, ensure that the power to your HVAC system is turned off to avoid any accidents.
Locate the Filter: Find the location of your AC filter, which is typically behind the return air grille or within the air handler unit.
Remove the Filter: Carefully remove the filter from its housing, noting its size and orientation for reinstallation.
Inspect the Filter: Check the filter for dirt, dust, and debris. If it’s visibly dirty, it needs cleaning or replacement.
Clean or Replace the Filter:
Washable Filters: If your filter is washable, rinse it under running water and use a mild detergent if necessary. Allow it to air dry completely before reinstalling.
Disposable Filters: Replace disposable filters with new ones. They are designed for one-time use and should not be cleaned.
Reinstall the Filter: Once cleaned or replaced, carefully slide the filter back into its housing, ensuring it’s securely in place.
Turn On the Power: Finally, restore power to your HVAC system and monitor its performance to ensure everything is running smoothly.

Can I Clean My AC Filter Myself?

Yes, you can definitely clean your AC filter yourself. It’s a simple task that requires minimal effort and can be done as part of your regular home maintenance routine.

What Is the Best Way to Clean Air Conditioning Filters?

The best way to clean air conditioning filters depends on their type:
Washable Filters: Rinse under running water and use mild detergent if needed.
Disposable Filters: Replace with new ones. Avoid cleaning disposable filters as they are designed for one-time use.

Can You Clean AC Filter and Reuse It?

Yes, certain types of AC filters, such as washable ones, can be cleaned and reused multiple times. However, disposable filters should not be cleaned and reused as they are intended for single-use only.

How Often Should AC Filters Be Cleaned?

AC filters should ideally be cleaned or replaced every 1 to 3 months. However, frequency may vary based on factors like filter type, indoor air quality, and usage patterns.

Is It OK to Run AC Without Filter?

No, it’s not recommended to run your AC without a filter. A filter traps dust, pollen, and other particles, preventing them from circulating in your indoor air and potentially causing respiratory issues or damaging the HVAC system.

How Do I Know If My AC Filter Is Dirty?

Signs of a dirty AC filter include visible dirt buildup, reduced airflow from vents, increased energy bills, and visible damage to the HVAC system components. Regular inspection and maintenance can help ensure optimal system performance and indoor air quality.
