How to Clean Your Air Conditioner Filter: 6 Simple Steps

Learning how to clean your air conditioner filter properly is critical for keeping your unit running efficiently. A clean filter reduces your air conditioner’s energy consumption and maintains healthy indoor air quality.

But this important maintenance task often gets overlooked. Here’s an easy-to-follow guide to help you clean your air conditioner filter effectively and keep your system running smoothly.

Why cleaning your air conditioner filter matters

Your air conditioner filter can capture dust, allergens, pollen and other airborne particles, ensuring the air in your home stays clean and healthy. A clogged or dirty filter forces your air conditioner to work harder, consuming more energy and reducing its overall lifespan.

Regular cleaning prevents functional issues, significantly enhancing the performance, efficiency and longevity of your air conditioning unit.

How to clean your air conditioner filter: step-by-step guide

Step 1: Turn off the air conditioner

Before you start cleaning, ensure your air conditioner is completely switched off at the main power source. This crucial step prevents electrical hazards and ensures safety during the cleaning process.

Step 2: Locate and remove the filter

Depending on the type of air conditioning system, accessing your filter may differ slightly. Follow the manufacturer or installer’s instructions for accessing the filter. Generally:

• Wall-mounted or split-system air conditioners: Gently open the front panel of your unit to access the filter.
• Ducted air conditioning systems: Carefully remove the return air grille, typically found on your ceiling, to access the filter.

Once you’ve located the filter, carefully remove it by sliding or lifting it out of its slot.

Step 3: Vacuum the filter

Use a vacuum cleaner to gently remove any loose dust and dirt from the filter’s surface. This initial cleaning step helps prevent dust from spreading when you rinse the filter later.

Step 4: Wash the filter

Rinse your air conditioner filter gently under lukewarm water to remove remaining dirt and debris. For particularly dirty filters, a mild detergent can help, but avoid using harsh chemicals or scrubbing aggressively, as this can damage the filter material.

For ducted systems with filters too large for your sink, you can use a hose with a gentle spray at this stage.

Step 5: Dry the filter completely

Allow your filter to air-dry fully. This step may take several hours, so plan accordingly. Reinstalling a damp filter can lead to mould growth and damage to your air conditioner, so ensure the filter is entirely dry before proceeding.

Step 6: Reinstall the filter

Once your filter is clean and completely dry, carefully return it to its original position, ensuring it’s securely and correctly placed. For wall units, close the front panel gently. If you have a ducted system, replace the return air grille with care.
