Coway Airmega Prox User Manual

Coway Airmega Prox

Specification

The specification is subject to minor changes to improve the product performance.

The coverage area of the air purifier is based on an area where the air cleaner can make two air changes per hour (ACPH). An air change per hour translates to how many times an air purifier can clean an area, assuming the height of the ceiling is 8 ft, in one hour. Therefore, * means four air changes per hour, which means that the cleaner can clean the area once every 15 minutes. And ** means two air changes per hour, which means that the cleaner can clean the area once every 30 minutes. And *** means one air change per hour, which means that the air purifier can clean the area once every 60 minutes. The energy efficiency of this ENERGY STAR-certified model is measured based on a ratio between the model’s CADR for Smoke and the electrical energy it consumes, or CADR/Watt.

OPERATION

Auto mode

The product automatically adjusts the airflow speed (Levels 1, 2, and 3) for efficient operation depending on the indoor air quality detected by the sensor. The mode is intended for general users’ convenience.

[Sleep mode (Only available in auto mode)]
When the machine’s light sensor determines that the space is dark for more than 3 minutes when in auto mode, the device enters sleep mode automatically (operates the same as silent mode). All indicators except the silent mode indication are turned off when in sleep mode. If the area is bright for more than 5 minutes, the purifier will exit sleep mode and revert to auto mode.

Eco mode

Although it operates the same way as the auto mode, it pauses the purification process for 30 minutes if the PM2.5 concentration is maintained at 2㎍/m³ or less for 10 minutes. When the machine is in Eco Mode, all indicators except for the air quality and Eco Mode indicators are turned off. The purification is resumed when the PM2.5 concentration becomes 3㎍/m³ or higher or when there is a user input (pressing any button).

Silent mode

This setting reduces airflow speed during operation to create a quiet and comfortable environment. It consumes less power and produces minor noise during operations.

Turbo mode

Turbo mode accelerates the air purification process with a faster airflow speed equivalent to Level 3 in manual mode. At maximum airflow speed, it consumes more energy and may produce noise.
* Turbo mode lasts 10 minutes and reverts to auto mode.

Manual speed mode

The machine continuously operates with the airflow speed selected by the user. You can choose the airflow speed from Level 1, Level 2, and Level 3.

Setting function

[Light function]

You can change the control panel’s indication lights. Turn the product on, and press and hold the PM information button for more than 3 seconds to switch off the indicator lights. If you touch any button when the indicator lights are off, they will light up for 3 seconds. Press and hold the button for more than 3 seconds to restore the lights.

[Control Panel Lock function]

This function is useful for preventing unnecessary inputs. If you press and hold the Mode button for more than 3 seconds, it will disable all the buttons. To reactivate the controls, press and hold the Mode button for more than 3 seconds.

Cover open notification display

When opening the cover(s) while using the product. If either one or both covers are not detected as being properly installed, the product will cease, and the digital indicator will blink in “—”. Additionally, all other indicators will turn off. However, if both covers are properly installed, the product will return to its previous operation mode.

Air quality sensor sensitivity adjustment

Air quality indication guide

How to adjust the sensitivity of the air quality sensor

When you operate the product for the first time, the air quality sensor is set at the normal sensitivity. If the air quality indicator remains at “Very Unhealthy (Red)” or Good (Blue) for more than two hours, you can adjust the sensor’s sensitivity as follows.

1. While the product is operating, press the Airflow speed button and the PM information button simultaneously for more than 3 seconds.
2. Display the current air quality sensor sensitivity on the digital Indicator. To indicate that the air quality sensor sensitivity is being adjusted, the Level 1 Airflow Speed Indicator and PM1.0, PM2.5, and PM10 indicators are turned on.
3. Press the PM information button to change the air quality sensor sensitivity.
4. If the Airflow speed and PM information button are pressed and held simultaneously for more than 3 seconds, or if left alone for more than 7 seconds, then the selected air quality sensor sensitivity is applied.

MAINTENANCE

The Pre-filter maintenance indicator is turned on when the filter is used 100% and Max2 filter replacement indicator is turned on when the filter is used 95%. To deactivate the indicator and reset the filter usage, press and hold the airflow speed button for 3 seconds.

* If the Pre-filter maintenance notification indicator and Max2 filter replacement indicator are turned on at the same time, both are deactivated.

Forced filter usage reset mode

This function is to reset the filter usage if a user has cleaned or replaced the filter in advance before filter maintenance or replacement notification. Through this action, you can manage the usage of the Filter.

1. While the filter maintenance or filter replacement notification has yet to occur, press and hold the Airflow speed button for more than 3 seconds.
2. The filter maintenance indicator lights up and displays the current filter usage through the digital indicator. Press the Airflow speed button and select the filter to reset its usage. When choosing the filter, follow the following order.
   NOTE
   • Pre-filter (PRE) → Max2 filter (MAX2) → Pre-filter (PRE)
3. After selecting the filter, press and hold the Airflow speed button for more than 3 seconds to reset filter usage.
4. If the reset button is not pressed for more than 7 seconds, the Forced filter usage reset mode is canceled.

How to replace the filter

   CAUTION: If you use water to clean the Pre-filter, dry the Pre-filter in the shade before reinstalling it.
3. Dry off the pre-filter and mount it in the pre-filter frame. Then, combine the pre-filter frame with the cover, insert the cover into the lower hanger and upper hook precisely, then close the cover.
4. Press and hold the Airflow speed button on the control panel to reset the filter usage.
