Cleaning Your Split System Aircon Filter

The whirring of your split system air conditioner brings a wave of cool relief on a hot summer day. But behind the scenes, a hardworking filter traps dust, pollen, and other airborne nasties, ensuring you breathe clean air. 

A filter that isn’t cleaned regularly can become clogged. This hinders airflow and can cause other problems. In this guide, you will learn how to clean your split system aircon filter and find out when you need the help of a professional to ensure optimal performance.

The Power of a Clean Filter

More than just comfort, a clean filter offers significant benefits:

  • Improved Air Quality: A clogged filter becomes a breeding ground for allergens and dust mites, triggering allergies and respiratory issues. Keeping it clean helps remove these contaminants, allowing your air conditioning to circulate cleaner, healthier air throughout your home.
  • Enhanced Efficiency: A clogged filter restricts airflow, forcing your unit to work harder to maintain the desired temperature. This means you’re consuming energy at a higher rate, which can lead to increased electricity bills. Keeping your air conditioner clear of dust and debris will run more efficiently.
  • Extended Aircon Unit Lifespan: A strained air conditioning unit working overtime due to a clogged filter experiences greater wear and tear. Regular cleaning minimises stress on the system, promoting a longer lifespan of the unit.
  • Reduced Risk of Mould Growth: A moist and dusty environment within a clogged filter can be a breeding ground for mould. Regular cleaning helps prevent mould growth.

Signs Your Filter Needs Attention

Beyond routine cleaning, some telltale signs will indicate your filter’s need for immediate attention:

  • Excess Dust: Check your vents and the filter itself for dust accumulation. Excess dust is a sure sign that your filter needs thoroughly cleaning.
  • Reduced Airflow: No longer feeling the refreshing blast from your vents? A simple filter cleaning might be all it takes to get the cool air flowing freely again.
  • Uneven Temperature:  Is your thermostat set perfectly, yet some rooms feel like an ice cave while others resemble a sauna? Blocked ducts or a clogged filter in specific areas might be the reason for this frosty mystery.
  • Allergies: Is your family battling a surge in allergies during AC use? A dirty filter might be to blame.

The Art of Cleaning Your Split System Filter

Ready to tackle the cleaning yourself? Here’s a step-by-step guide to ensure a successful and safe process:

Preparation:

  1. Turn your AC unit off: Always ensure the system is turned off before starting any cleaning.
  2. Gather your cleaning supplies: 
    • Vacuum cleaner with a brush attachment
    • A flathead screwdriver  
    • A damp cloth for wiping.
    • Drop cloth to safeguard your floors from any dust fallout
  3. Protect yourself: A dust mask and gloves can minimise your exposure to dirt and dust inhalation.

Cleaning the Filter:

  1. Locate the filter: Your split system filter is usually a rectangular panel on the indoor unit. If you are unsure, consult your manual.
  2. Remove the filter: Gently remove the filter by following the instructions in your manual. It typically involves releasing tabs or clips holding it in place. 
  3. Vacuum the filter: Use the brush attachment on your vacuum cleaner to clean both sides of the filter.
  4. Wash the filter (optional): Rinse the filter with lukewarm water for a deeper clean. If needed, add a mild detergent solution, but avoid harsh chemicals. Rinse the filter thoroughly with clean water to remove any soap residue.
  5. Drying the filter: Never reinstall a damp filter. Air dry it in a shaded area or use a fan to speed up the process. A damp filter can encourage mould to grow.
  6. Replace the filter: Once the filter is clean and dry, carefully reinstall it back into the unit, following the instructions in your manual.
