The Membrane Solutions MSA3 is a relatively new air purifier on the market, while the Winix 5500-2 is a well-known, top-notch air purifier. In this article, you will find out whether the Membrane Solutions beat the unbeaten Winix 5500-2 air purifier. But, before diving into the article more deeply, let’s compare their basic specifications.
Winix 5500-2 is a large air purifier that covers rooms up to 360 sq. ft., while the Membrane Solutions MSA3 covers rooms up to 210 sq. ft. The Winix uses a four-stage filtration technology, and it has an ionizer, which is the fourth stage. Luckily the Winix 5500-2 is CARB certified, which means it doesn’t produce an unallowed amount of ozone. The Membrane Solutions, on the other hand, uses a three-stage filtration technology. It doesn’t have an ionizer and is 100% safe to use.
When speaking of build quality, I must say that they both are of very good quality, and their construction is okay. The only complaint I have is the plastic on Membrane Solutions, which gets stains quickly.
What else I want to say is that Winix has much more advanced features, from which I like the air quality sensor and auto mode the most. Membrane Solutions doesn’t have that many features but has just enough for everyday usage.
Keep reading and find out which one performed better in performance tests, which use less power, which is quieter, and which is a better buying option.
