The Final Verdict
The most important thing is that both of these Coway air purifiers do an amazing job at cleaning the air in large rooms. We liked how you could hear the fan increase when the air was not as pure, and the LED lights were quite accurate too. The size and design really were identical, so this didn’t factor into the decision. We felt that the Coway Airmega 400S was the winner today. Essentially, they are the same air purifiers but now that the app is better and it works with Alexa, the ease of use is better and for a couple of dollars more, well worth it.
