Today’s comparison is between two totally different air purifiers, the Blueair 411 and the Coway AP-1512HH. The biggest difference between these two is their room coverage and advanced features. Even though this battle may be unfair, I decided to write this article due to many inquiries about comparing the Blueair and Coway.
Coway AP-1512HH covers rooms up to 361 sq. ft., while the Blueair 411 covers rooms up to 161 sq. ft. The most significant difference between these two devices, in addition to room coverage, is in their features. The Coway is equipped with a host of advanced options, of which I especially like the air quality sensor, ECO mode, and auto mode. On the other hand, the Blueair 411 is a minimalist air purifier, which doesn’t have any advanced feature.
Blueair stands out for its washable pre-filter, minimalism, and ease of use, while extremely high-quality filters and high reliability characterize the Coway.
In the following, I will compare these two devices in detail, show the results with all the tests done, and compare their specifications. Based on all mentioned, I will determine the winner and a better choice for buying.

Which One Does It Better?
After in-depth analysis, I chose the Coway AP-1512HH as a better choice to buy and a far better option than the Blueair 411.
There are many reasons, and I would single out the True HEPA filter, reliable air quality sensor, ECO mode, ionizer, as well as long-lasting filters. In addition, Coway covers much larger rooms than Blueair.
The Blueair 411 is also an excellent air purifier, and I would recommend it if you need a device for a smaller room where Coway would be too strong.
