What if my air conditioner temperature is not cool enough?

Step 1. Slide the filter off of the unit.

Step 2. Use a soft brush or vacuum cleaner to remove any dust or debris on the filter. 

Step 3. If the filter has a lot of dust, soak the filter for about 30 minutes in soapy water and then rinse it. 

Step 4. After rinsing the filter, dry it in a well-ventilated area. 

Step 5. Reinstall the filter.

Note: 

• Do not scrub the air filter with a hard-bristled brush or other rough cleaning tool.
• If the air filter is not dried completely or is dried in a confined (or humid) area, a bad odor can occur.
• Do not expose the air filter to direct sunlight when drying it.

If your air conditioner is a floor standing type with an inverter, check the following steps outlined below. The inverter floor standing model has two types of filters.

• Full HD filter: It filters out the large particle dust of the incoming air. 
• Zero filter: It traps small dust particles within the air. It is washable and can be used semi-permanently.
  

Cleaning the Full HD filter

Step 1. Pull out the Full HD filter according to the direction of the arrows shown in the image below.

Step 2. Remove dust with a vacuum cleaner or running water. 

Step 3. Dry the filter completely in a shaded area.

Step 4. Push the Full HD filter to the end in the arrow direction so that it can be completely fixed.

Note: 

• Clean the Full HD filter every 2 weeks.
• Cleaning time frame may differ depending on the usage and environmental conditions. 
  

Cleaning the Zero filter

Be careful with the sharp rear surface of the Zero filter. You may injure your hands. 

Step 1. Remove the lower Full HD filter. Grab the handle on the Zero filter and remove it by pulling it in the direction of the arrow shown in the figure.

Step 2. Soak the filter in the water and shake it up and down a few times. 

Step 3. Dry the filter in a ventilated area.

Step 4. Push the Zero filter in the direction of the arrow and make sure it is fixed in the correct position. Put the lower Full HD filter back.

Note: 

• Clean the Zero filter every 3 months. (Based on 8 hours of use per day.)
• Cleaning time frames may differ depending on the usage and environmental conditions.
