How to Clean Your Aircon Filter

Why Cleaning Your Aircon Filter Matters

Regular aircon cleaning, especially around the filter, offers several benefits to the system :

• Enhanced Indoor Air Quality: Clean filters trap dust and allergens, helping maintain a fresher and healthier environment.
• Lower Energy Costs: A clogged filter restricts airflow, increasing energy consumption as the unit works harder to cool your space.
• Extended System Longevity: By minimising strain on the system, a clean filter helps prevent wear and tear, reducing the likelihood of costly repairs or premature replacement.

Understanding how to clean your aircon filter and keeping it part of your maintenance routine will ensure your system performs optimally, all while saving you on energy and repair costs.

How Often Should You Clean Your Aircon Filter?

To get the most out of your system, it’s best to clean your air conditioning filter at least once every three months. However, during high-use periods, like summer, or if you have pets or live in a particularly dusty area, monthly cleaning may be more appropriate.

Additionally, if you notice signs like reduced airflow, slight odours, or a gradual increase in your energy bills, it’s a good time to check and clean the air filter outside of your regular schedule.

The Step-by-Step Guide

With a few simple steps, you can effectively clean your aircon filter, helping your unit run more efficiently and ensuring better indoor air quality.

1. Turn Off the Power

Begin by switching off the air conditioner and unplugging it if possible. This minimises the risk of electric shock and protects your system during cleaning.

2. Locate and Remove the Filter

The filter’s position will depend on the type of air conditioner, but here’s where it’s commonly found:

• Split-System Units: Open the front panel of the indoor unit, where you should see the filter near the top, which can be easily slid out.
• Window Units: Typically located behind the front grill; removal may require unscrewing the panel.
• Portable Units: Often accessible through a back panel.

If you’re uncertain, consult your unit’s manual to locate the filter and understand how to remove it safely.

3. Inspect the Filter for Dirt and Damage

After removal, inspect the filter for visible buildup and signs of wear. If it appears overly dirty or damaged, it may be more effective to replace the filter rather than clean it. Most air filters last around a year, though high-use environments may require replacement sooner.

4. Vacuum the Filter

For a quick clean, use a vacuum cleaner with a brush attachment to remove surface dust from both sides of the filter. This step is especially useful if you clean your filter frequently and provides a fast solution for regular maintenance.

5. Wash the Filter with Water and Mild Soap

For a more thorough clean, washing the filter is often recommended:

• Fill a basin or sink with lukewarm water and add a mild detergent.
• Gently submerge the filter and use a soft brush, such as an old toothbrush, to scrub away dirt and debris.
• Rinse with clean water to remove any remaining soap.

Avoid using hot water or harsh chemicals, as they can damage the filter material.

6. Allow the Filter to Dry Completely

Place the filter in a well-ventilated area to air dry. Make sure it dries completely before reinstalling it to prevent mould growth and damage. This can take several hours or overnight, depending on humidity and filter thickness.

7. Reinstall the Filter

Once dry, slide the filter back into its designated slot, ensuring it fits securely. Proper placement is crucial for the air conditioner’s performance and airflow.

8. Restore Power and Test the Unit

After reinstallation, plug the unit back in and turn on the power. Your air conditioner should now deliver improved airflow and operate more efficiently.

Additional Tips to Maintain Your Air Conditioner

While knowing how to clean your aircon filter is essential, there are additional practices that help ensure long-term efficiency:

• Clean the Vents: Dust accumulates on the vents, potentially obstructing airflow. Wipe them down regularly with a damp cloth.
• Check for Leaks: Inspect for any visible leaks or unusual sounds, which may indicate that professional maintenance is required.
• Use a Timer: Many air conditioners have timers that allow you to control usage, reducing strain on the system and lowering energy consumption.

When to Consider Professional Maintenance

While regular aircon cleaning is manageable for most of us, some issues require a professional touch. If you’re finding occuring performance issues, like a loss of cooling capacity or unusual noises, it may be time to call in a professional.

Routine air-con servicing helps diagnose and prevent potential problems, ultimately ensuring the best performance and longevity.
