I am a huge fan of Blueair air purifiers, especially their Blue series. At the same time, I like how Xiaomi innovates in its air purifiers, and I appreciate the features they are constantly improving.
In this article, I will compare the Blueair 411 Auto and the Xiaomi 4 Compact, two small air purifiers that have similar coverage but different features. The Xiaomi can cover rooms up to 206 sq. ft., while the Blueair can cover rooms up to 190 sq. ft. These air purifiers can clean the air 4.8 times in one hour in suggested room sizes.
The Xiaomi 4 Compact uses a three-stage filtration technology consisting of a pre-filter, a Xiaomi’s High Efficiency-Filter, and an activated carbon filter. The Blueair 411 Auto, on the other hand, doesn’t have a True HEPA filter; it has a lower grade filter named Particle Filter. However, it has a washable pre-filter and HEPASilent technology.
Regarding the features, the Xiaomi 4 Compact is a clear winner here. It has many innovative options, can be connected to a smart app, and much more. The Blueair 411 Auto is somewhat minimalistic, but it has its trump cards as well. They both have an air quality sensor, air quality indicator, and auto mode features. These are some of my favorite features an air purifier could have.

Which One Does It Better?
Due to its better-optimized motor of just 10W, the Blueair 411 Auto won the power usage test. But it also won in the performance test, even though it doesn’t use a True HEPA filter. As for the noise tests, they produced similar results, but the Blueair produces some strange sounds at the highest speed, so I rated it lower in this test.
In my opinion, the Blueair 411 Auto would be a better buying option. It has great filtration technology, looks modern, has some advanced features, and doesn’t use too much power. However, if you are looking for an air purifier almost as good as the Blueair 411 but with some smart features and innovations, then the Xiaomi 4 Compact would be a fantastic option as well.
