Coway Airmega 200M Air Purifier: Key Features


If you are interested in knowing more about what the Coway Airmega 200M air purifier does besides filtering out the air in your home, you should read about its features and learn what it does, how to operate it, and most importantly, whether it is the air purifier you need.

Design and size

The Coway Airmega 200M is simple and compact in its design, size, and color. This air purifier is available in two versatile colors: black and white, making it an appliance that will complement any room design in your house. As per the dimensions, the Coway Airmega 200M air purifier is 18.5 inches in height (46.99 cm) and 16.8 inches in width (42.6 cm), making it a relatively small appliance. In addition, the Coway Airmega 200M air purifier is lightweight and portable because it only weighs 12.3 lbs (5.5 kg).

Air filters

One of the best features of the Coway Airmega 200M air purifier is, without a doubt, its highly rated, famous 4-stage air cleaning system. This air cleaning system consists of:

  • A pre-filter: As is the case with all pre-filters on air purifiers, the one in the Coway Airmega 200M catches the larger particles and allergens in the air, i.e., hair (pet and human), dust and dust mites, etc. What makes this pre-filter special is that it is washable, meaning you can use it permanently and won’t need to replace it.
  • An activated carbon filter: The activated carbon on this filter tackles the odors and odor-causing gasses in your home, i.e., cooking smells, cigarette odor, pet odor, etc.
  • A True HEPA filter: Perhaps the most integral part of the air cleaning system, the True HEPA filter catches 99.99% of extremely fine airborne pollutants, i.e., bacteria, mold, viruses, pollen, germs, etc. This filter has an antimicrobial treatment to prevent the spread of contaminants.
  • An ionizer: The last part of the air cleaning system includes generating an electrochemical reaction by the bipolar device. This is an extra step to combat airborne viruses and bacteria.

Room coverage

The Coway Airmega 200M air purifier is ideal for spaces up to 360 ft2. It delivers 4 ACH (Air Changes per Hour), meaning you can also use it to clean rooms larger than 360 ft2 but for fewer air changes per hour. The CADR (Clean Air Delivery Rate) for this air purifier is 246 cfm for dust, 233 cfm for smoke, and 240 cfm for pollen.

Smart features

The Coway Airmega 200M air purifier has several features that make it easy to use and, most importantly, efficient. These are the smart features you can find on the Coway Airmega 200M air purifier:

  • An Eco Mode: This is a perfect feature for those who want clean air but also save energy in the meantime. When this feature is activated and the appliance doesn’t detect air pollution for 30 minutes, the air purifier stops working to save energy and only starts again when pollution is detected.
  • An Auto Mode: When this feature is activated, the air purifier will work based on the air quality detected by the appliance, giving you clean air as needed throughout the day.
  • A timer: Say you want to use the air purifier for a certain amount of time but won’t be there to select a setting; what do you do? This is where the timer feature comes in handy. You can set a timer (1, 4, or 8 hours) for your air purifier to operate when you are not there.

Buttons and indicators

On the Coway Airmega 200M control panel, you will find several buttons and indicators for a specific setting and purpose of the air purifier. 

  • Air quality indicator: This indicator lights up when the sensor detects dust particles in the air and immediately activates the fan at a suitable speed to take care of it. 
  • An air filter indicator: This indicator lights up when your Coway Airmega 200M needs a filter replacement, and it’s pre-filter washed. This ensures maximum efficiency.
  • The on/off button
  • Timer button
  • Fan speed button
  • Ionizer button
