How to clean air conditioner filters

It is normal for the unit to generate some noise while operating. A high level of dust in the filter may reduce the wind or cause abnormal noise.

Recommended filter cleaning cycle

• Cleaning the filter when the ‘CF’ code appears on the indoor unit display. After cleaning and reinstalling the filter, reset the filter cleaning reminder. 
• The time between cleanings may vary depending on the usage and environmental conditions. 
• If the use environment is subject to excessive dust exposure, filter dust blockage may occur before the 'CF' code appears on the indoor unit.

Detach the filter

• Turn off the air conditioner and disconnect the power supply before cleaning.
• Hold and pull both sides of the wind-free panel until it comes off of the air conditioner.
• [Filter removal for the model without an upper cover] Slide the filter off of the unit.
• [Filter removal for the model with an upper cover] If the product has an upper side cover, lift the upper cover up and then release the filter.
  

Cleaning the wind-free panel and filter

• Use a soft brush or lukewarm, damp cloth to clean the surface of the panel.

• [Cleaning the cover of wind-free panel] If the panel is covered with the excessive dust, rinse it under running water.
• Use a vacuum cleaner to remove any dust or debris on the filter.
• If the filter has excessive dust, rinse the filter under running water and scrub with a soft brush.
  

Drying the filter

• After rinsing the filter, let it air dry in a well-ventilated area that is out of direct sunlight.

Reassembling the wind-free panel and filter
