How to Clean an Aircon Filter: A Guide

It can be frustrating to notice that your aircon isn't cooling effectively, especially when living in Singapore’s heat.

Often, a dirty air conditioner filter is the culprit behind such poor performance, as the component directly affects your unit's airflow and overall efficiency.

Fortunately, maintaining it can be simple. This blog will guide you on how to clean an aircon filter, helping you restore a refreshing breeze to your home quickly and easily.

Why Aircon Filter Cleaning is Crucial

Regular aircon filter cleaning is essential for maintaining your unit’s efficiency and ensuring a healthy living environment for your family.

• Electricity bills: A clogged aircon air filter restricts airflow, forcing your unit to work harder. As such, regular cleaning helps save energy and reduce costs.
• Health: Dirty filters trap harmful dust, mould, and allergens. Keeping them clean prevents these particles from circulating and degrading your indoor air quality.
• Function: Consistent filter maintenance protects internal components like cooling coils, extending the lifespan and reliability of your entire air conditioning system.

How Often Should an Aircon Filter Be Cleaned?

In Singapore's humid climate, you should generally clean your aircon filters every two to four weeks.

However, certain factors may necessitate a more frequent schedule:

• Owning pets: Fur and dander accumulate quickly, blocking the mesh and reducing the efficiency of your cooling system.
• Smoking indoors: Smoke particles and residue clog filters rapidly, requiring constant attention to maintain clean indoor air.
• Living near dusty roads: High outdoor particle levels enter your home, settling on the filter and restricting airflow.
• Heavy usage: Running your unit nightly places constant strain on the filter, causing dust to build up much faster.

What You Need for the Job

Before you begin cleaning your aircon air filter, ensure you have the following essential tools and materials ready to make the task as efficient as possible.

• Soft brush (such as a toothbrush or paintbrush)
• Mild liquid soap or detergent
• Clean water source (sink or shower)
• Microfiber cloth or an old towel
• Vacuum cleaner with a brush attachment
• Step ladder (if the unit is mounted high)

A Step-by-Step Guide on How to Wash an Aircon Filter

1. Turn Off the Power

Always prioritise your safety by switching off the unit and unplugging it from the power socket before you start working. This essential step protects you from electrical hazards.

2. Open the Front Panel

Gently unclip or lift the front cover of your indoor unit to access the interior. If you are unsure of the mechanism for your model, consult your manufacturer’s manual to avoid accidental damage.

3. Remove the Air Filter

Locate the mesh filters positioned directly behind the panel and gently slide them out of their designated slots. Handle these components with care, as the frames can be delicate.

4. Vacuum Loose Dust

Before applying water, use a brush attachment to vacuum the aircon air filter surfaces and remove dust. This prevents debris from turning into a messy sludge that is difficult to rinse away.

5. Wash with Mild Soap

Mix mild soap with lukewarm water and gently scrub the mesh with a soft brush to remove stubborn grime. Be careful not to tear the delicate material.

6. Rinse Thoroughly

Thoroughly rinse the filter under running water to remove all soap suds and lingering dirt. Ensure you run the water through the back of the mesh to push trapped particles out rather than forcing them deeper into the mesh.

7. Dry Completely

Shake off excess water and leave the filter to air-dry in a shady, well-ventilated area. Avoid placing it in direct sunlight as excessive heat can warp the filter’s plastic frame.

8. Reinstall and Close

Once the aircon air filter is completely dry, slide it back into the unit until it clicks firmly into place. Finally, securely close the front panel to complete the maintenance process.

Mistakes to Avoid

Keep these common mistakes in mind to avoid damaging your aircon air filter during cleaning:

• Using bleach or abrasive cleaners: As these substances can damage the filter’s protective coating, opt for mild detergents and soaps instead.
• Reinstalling a damp filter: Moisture encourages mould growth inside your unit, negatively affecting your air quality. As such, wait for the filter to dry completely before installing it.
• Using stiff brushes: Avoid tearing the fine mesh on your filter by using soft bristles only.
