In today’s article, I will compare two totally contrasting air purifiers. I will compare the Blueair 411 and the Membrane Solutions MSA3 air purifiers.
The Blueair is a minimalistic air purifier with no features but with a washable pre-filter and very low energy consumption. It is intended for rooms of up to 161 sq. ft., uses a three-stage filtration technology, uses a motor of just 10W, and made extraordinary results in performance tests.
On the other hand, the Membrane Solutions MSA3 has some basic features such as a timer, display off, display lock, and similar. It is suitable for rooms of up to 210 sq. ft., uses a three-stage filtration technology, and has a True HEPA filter, which is not the case with the Blueair 411.
I like the Blueair’s simplicity, build quality and design principles, and it is, in my opinion, much more modern than the MSA3. Also, its build quality is way better.
Both air purifiers come with a 2-year warranty. But, which one is an overall better option, which did better in tests, and which is my absolute buying recommendation you will find out in the continuation of the article.

Which One Does It Better?
I must say that these are exceptionally air purifiers performance-wise, and even though the Blueair made better results in the tests, I have to praise the MSA3’s performance as well.
After analyzing all the specifications, characteristics, and test results, I declare the Blueair 411 as the winner and the better buying option than the Membrane Solutions MSA3.
It has provided better results in performance tests, is much cheaper to maintain, has a better build quality, and is much easier to use.
