How to Monitor Your Indoor and Outdoor Air Quality

Understanding both your indoor and outdoor air quality is key to protecting your health. Outdoor pollutants from sources like traffic and industry can infiltrate your home, mixing with indoor contaminants from cooking, cleaning, pets and more. Monitoring air quality in and outside your home with advanced sensors and apps lets you see these threats in real time and can provide crucial insight into your environment for better health and wellbeing.

Not only is it important to have clean, breathable air for yourself and your loved ones, it’s equally vital to know what’s in the air you breathe. With a Coway Airmega, you can do just that.

Knowing is half the battle

With every model of the Airmega, you can know in real time what the condition of the air is in your home. Even better, it’s as simple as looking at the brightly colored LED indicator ring located on the front or top of the purifier, depending on the model.

For Wi-Fi-enabled devices, Coway’s IoCare app helps you monitor indoor air quality and filter status from your phone. You can set the unit timer, receive real-time outdoor air quality updates and even activate the air purifier remotely.

Monitor in real time…

Airmega's Smart Mode adapts to its environment, using only the power necessary to clean your air's current quality. When paired with the scheduling function in the app, you get more flexibility and control, and can be sure that the air quality is always great in your home.

 We all know that outdoor air pollution can affect indoor air. With the IoCare app, you can monitor outdoor air-pollution levels for cities in your area to know when it’s safest to go outside. Meanwhile, Coway Airmega helps you track a room’s air quality over time, so you can find out when air quality is at its best and worst.

…and from anywhere

One of the most useful operations that the app helps you perform is speed control and smart mode. If you want to save energy when you’re not at home, all you need to do is set fan speed and access smart mode controls remotely when you’re connected to Wi-Fi. With smart mode, your Airmega will adjust power based on the air quality, time and lighting in the room. 

With Airmega and it’s innovative real-time air quality monitoring features, you can rest assured that your home’s air will be breathable and safe, taking care of you while you take care of life’s other pressing matters. And when working in concert with the IoCare app, you have the ultimate control of the air in your home, whenever and wherever you need it.

For instructions on how to pair your Airmega with your smartphone, here’s a video.


1Coway air purifiers have been proven to trap dust, pollen, dander, viruses and bacteria in the air based on KCL (Korea Conformity Laboratories) testing.They have been tested in a 30㎥ size chamber according to the Korea Air Cleaning Association standard (SPS-KACA 002-132:2022 Modified) to measure the 0.01㎛ size of particle removal rate. It was tested on maximum airflow speed in normal room temperature and humidity conditions. The performance may vary in the actual living environment of customers.

3Aerosol test conducted in a Biosafety level 3 laboratory with two Coway air purifier models, Coway Airmega 250 and 400 for removal of SARS-CoV-2 Aerosol by US based MRI Global, a not-for-profit laboratory and partner of US Department of Defense. The test was conducted in a 13.1ft3 chamber. Virus was aerosolized for 15 minutes and the product was turned on high for 2 minutes. Result showed each product effectively removed over 99.98% of the SARS-CoV-2 in 2 minutes. This is a result from a laboratory experiment condition and result may vary in different conditions. This result does not imply it kills SARS-CoV-2 or prevents the transmission of Covid-19. Coway Airmega 250S and 400S are identical to the tested models and has equal performance with an additional mobile connectivity function.

4The concentration of ammonia, acetaldehyde and acetic acid were proven to be removed within 30 minutes by FCG Research Institute, Inc. Human Life Science Lab. It is not a demonstration result in the actual use space. Not all odors and gases may be supported. → Tested with Coway Airmega 150, 160, AP-1512HH, AP-1512HHS, 400, 400S

5The 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 a ceiling to be 8 ft, in one hour. Therefore ** means two air changes per hour means that the cleaner can clean the area once every 30 minutes and * means air changes per hour means that the air purifier can clean the area once every 60 minutes.
