How To Clean Your Aircon Filter
A dirty air filter can easily result in error codes that disrupt the normal day-to-day operation of your air conditioning unit. It can also lead to strange noise issues coming out of your unit or even to bigger maintenance issues as well as impact the lifespan of your air conditioner. Cleaning your aircon filters regularly might sound daunting and laborious, but there’s nothing like the cool, fresh-smelling breeze coming out of a newly cleaned air conditioner to lighten up your mood and instantly enliven any drab, stuffy area in your HDB flat.
Cleaning the Filter of an Window-Type Air Conditioning Unit
A twice-monthly cleaning of the air filter in your window-type AC is enough to ensure your air conditioner is in optimal condition to keep your living spaces comfortably cool during the hottest hours of the day. Before proceeding with the clean up, turn off and unplug the aircon from the power socket first.
Gently remove the front panel and unclip the air filter underneath it. If there are hair strands or debris stuck on the air filter, use a vacuum cleaner or a brush to whisk them away. Scrub the filter under soapy water and drain it thoroughly of any soap residue. Leave it out in the open to air-dry completely but not under direct sunlight because the material used in the aircon filter is not designed for sun exposure.
While you wait for the filter to dry, wipe the aircon grill, sides, and front panel with a cloth that has been soaked in water with mild detergent. Dust the fan coil and aluminum fins with a soft-bristled brush. Remove the drain tray, empty it of condensation droplets, and clean the moldy water stains on its surface. Don’t forget the drain pipe. You can use a pressurized nozzle to unclog the drain pipe.
You might also want to disinfect the air conditioner, too. Spray the grill and the front panel with hydrogen peroxide. And make sure everything is dry before you put the aircon parts back in.
