Why is My Coway Air Purifier Odor Light Orange?

Whenever your Coway air purifier has glowing or blinking warning lights, they indicate a specific issue based on their pattern and color.

Red or orange lights, depending on your exact Coway model, typically mean high air pollution or an issue with air passing through your device.

Here is a list of the most frequent causes of Coway air purifier odor light orange or red:

Now that you know why the issue of a blinking orange or amber light commonly presents itself, let’s try out some troubleshooting steps.

How to Fix Coway Air Purifier Odor Light Orange

Tip: Ensure your Coway purifier is in the right room size; an undersized purifier won't clean effectively.

Step #1: Reset Your Coway Air Purifier Filter Light

A very common cause of the Coway air purifier light glowing red or orange is a software malfunction.

If this is the case and your filters don’t actually need servicing, the warning light can typically be reset.

The red or orange light is typically linked to a filter replacement reminder.

Here are the steps to reset your Coway air purifier filter replacement timer:

1. Power off your Coway air purifying system.
2. Hold the filter reset button for a few seconds.
3. Wait for the indicator light to blink or beep.
4. Release the button and then turn the unit back on.
5. Allow the system to complete a full air quality check.
6. Check if the orange or amber Coway odor light turns off or changes color.
7. If not, repeat the process one or two more times by resetting the filter light.

If the light still glows even after resetting the timer, perhaps the underlying issue is related to the air quality or the filter itself. 

Note: You can use the Auto mode for your Coway air purifier to configure itself based on the environment's air quality.

Step #2: Reposition Your Coway Device 

Sometimes, your Coway air purifier will glow in amber or orange, indicating that the air quality has diminished.

A clever workaround for this scenario is to physically relocate the air purifier temporarily and see if the orange light disappears.

Here are the proper steps to reposition your Coway air purifier to ensure optimal conditions:

1. Move your Coway air filtration system to a different area in the room.
2. Ensure it’s at least 15 inches away from walls for proper airflow.
3. Avoid placing the unit near strong odor sources.
4. Check if the odor sensor is working correctly in the new location.
5. Run your Coway purifier continuously for a while.
6. If the Coway air purifier is still blinking orange, you can attempt to change the room where it’s placed again. 
7. If the issue still persists, move on with the next steps.

Note: Check the air sensors of your Coway air purifier for obstructions and clean them if needed.

Step #3: Clean the Pre-Filter 

If you have repositioned the Coway air purifier and tried resetting the filter warning lights, but the issue persists, it’s likely your device is struggling to take in air.

To fix this issue, you need to clean and check the pre-filter for any issues.

1. Turn off and unplug your Coway air filtering unit.
2. Open the device side or top panels (depending on your exact Coway model) to access the pre-filters.
3. Gently remove the pre-filter by ensuring you don’t damage or bend the plastic latches.
4. Use a vacuum to remove dust from the pre-filter and then rinse it with warm water to get rid of the more persistent dust particles. 
5. Let the pre-filter dry completely after being washed; don’t reinsert it otherwise. 
6. Reinsert the pre-filters and close the unit panels you removed earlier.
7. Restart the Coway air purifier to see if the odor light resets.

Note: True HEPA and Odor filters inside your Coway purifier should never be cleaned or washed.

Step #4: Check Your Room Ventilation

An issue commonly causing an amber warning light is when your Coway struggles to get sufficient airflow.

This can also happen if the room in which you are placing the purifier is too humid or too small.

Here are the correct steps to ensure your Coway air purifier has sufficient airflow:

1. Open windows to increase airflow in the room with the Coway purifier.
2. If possible, turn on a fan to help circulate fresh air, but never place your Coway air purifier directly underneath an AC unit.
3. Close the windows fully if outdoor air quality is poor.
4. Run the air purifier on its highest setting for at least half an hour.
5. Allow the purifier to cycle the air several times – this is to ensure that the air quality sensor gets a better reading. 
6. Monitor the Coway odor light to see if it changes back to normal.

Note: Never place your Coway air cleaner in a palace with open windows, as this can strain the device.

Step #5: Adjusting the Air Purifier Settings

Having incorrectly dialed-in settings for your Coway device can cause it to not cycle through the air properly, resulting in an orange alert.

To prevent this from happening, you have to examine your Coway device settings and optimize them.

Here is how to adjust your Coway air purifier settings to better filter air:

1. Plug it in, power it on, and then set the Coway air purifier to run in auto mode.
2. Use Coway’s built-in timers to run the purifier for extended periods of time, such as at least one to two hours.
3. If your air purifier gradually reduces its fan speed, it means it’s filtering air efficiently.
4. If your model has an air particle ionizer, check and adjust the ionizer settings if your model includes this feature.
5. Ensure the air quality sensor is unobstructed when you are placing your Coway device; there should be no objects covering it, as this can cause a false air quality reading.
6. Reevaluate the odor light status after your Coway has been running for a while.

Note: Your Coway device might have a sleep mode that lowers the fan and air filtration speed.

Step #6: Replace The Coway Air Purifier Filter

If you have changed your air purifier settings, yet there is still an odor of orange light glowing, you should replace the primary filter.

Most Coway models use a HEPA filter that sadly can’t get cleaned and has to be replaced as its filter captures particles deep within that can’t be reached.

Here are the general outlines on changing your Coway air purifier HEPA filter:

1. Turn off and unplug your Coway air cleaner.
2. Remove the front panel to access the filters.
3. Take out the old odor filter and remove any pre-filters that precede the main filter.
4. Vacuum around the filter area to remove dust to ensure the new filter has a clean environment.
5. Insert the new HEPA or odor filter compatible with your purifier model.
6. Put back the front and side panels on your Coway device.
7. Plug in and power on the device to reset the odor light.

Note: Check that you order the proper HEPA filter, as not all Coway filters are compatible with your device.

Step #7: Ensure the Environment is Properly Cleaned

Coway air purifier orange light blinking can be due to an insufficiently clean environment.

Even if your HEPA filter and pre-filters are clean and the device uses the proper settings, nothing can substitute proper room dust removal.

Here is how to ensure your Coway air purifier can manage the air quality without overloading:

1. Thoroughly clean the room where your Coway air purifier operates.
2. Remove garbage or any items that could cause strong odors.
3. Clean carpets, fabrics, and furniture to reduce accumulated dust.
4. After cleaning, run your air purifier on a high setting.
5. Allow the purifier to operate for several hours.
6. Observe if the odor light indicator improves after the room is cleaned.

Note: Never put any covers or fabrics to dry on top of the air purifier exhaust vents.

Quick Recap

To fix the Coway air purifier odor light orange, start by checking its operating environment, resetting the filter replacement button, and cleaning the pre-filter.

Install a new filter if needed.
