HOW TO CLEAN AN AC FILTER

It may seem an obvious first step, but always ensure that your air-conditioning system is turned off. It is best to allow some time between turning it off and starting to clean, as it will let any polluted or dirty air out of the system.

STEP 1 - POWER OFF

Most modern air conditioning units will have a release handle, allowing quick and easy opening of the unit for closer inspection. However, some units may require some unscrewing, so ensure you have the correct type of screwdriver if this applies to you.

STEP 1 - POWER OFF

The easiest way to remove the built-up dirt and dust is with a vacuum cleaner, though for a deeper clean, water is required.

STEP 2 - CLEANING THE FILTER

It would be sensible to do this over a sink under the tap, in the bath using the tap or shower head, or outside in the yard with your garden hose. You can run the water through the filter to clear out blockages and remove any grime that has built up around the frame of the filter.

STEP 2 - CLEANING THE FILTER

It is imperative that you let any air filter dry fully before placing it back into the air-conditioning unit. A wet filter will clog easily and spray out tiny droplets of dirty water that could cause discomfort in the lungs of anyone who breathes them in

STEP 3 - DRYING THE FILTER

If time is of the essence or the air is too damp for easy drying, then it's ok to use a hairdryer as long as you use its cooler settings. Too much heat could damage the structural integrity of the filter and its frame, making it warp out of shape and no longer fit into the unit.

STEP 3 - DRYING THE FILTER

Now you have a clean filter, your air-conditioning unit should provide effective filtration and smooth, untroubled airflow.

STEP 4 - RE-INSTALL THE FILTER

Carefully install it back into the unit as you found it, ensuring that it sits firmly in place. Make certain that nothing is catching or sticking out, and then close the lid as required.

STEP 4 - RE-INSTALL THE FILTER

After re-installation, allow the air conditioner to run for a little while and quickly see the improvement in performance.
