Many air purifier brands have been born on the market in recent years. One such brand is Membrane Solutions, and I had the opportunity to test one of their models, the MSA3 air purifier.
In this article, I will compare Membrane Solutions MSA3 and GermGuardian AC4825 air purifiers. These two air purifiers cover almost identical room sizes. They have made approximately identical results on all tests and are also extremely competitive.
Membrane Solutions MSA3 covers rooms up to 210 sq. ft., while Germguardian AC4825 covers rooms up to 167 sq. ft. Neither of these air purifiers has advanced features to highlight so that we can classify them as minimalistic air purifiers. I want to mention that the sleep and turbo modes on the Membrane Solutions MSA3 are just an easier way of switching to the lowest or highest speed.
The GermGuardian AC4825 uses a 3-stage filtration technology. I like that it has a UV-C light as one of the filtration stages. The Membrane Solutions MSA3 also uses 3-stage filtration technology but without UV-C light. What I like is that both devices use a True HEPA filter.
Below you will find the specification table where I compared their performance, noise levels, operating costs, and specifications.

Which One Does It Better?
After a detailed comparison of their specifications, the results on all tests, and other characteristics, I concluded that the GermGuardian AC4825 is a slightly better buying option.
The reasons are many, but I would single out a slightly better performance, a more reliable brand, and a better build quality as the most important things. However, the Membrane Solutions MSA3 is also a very good air purifier, and not a much worse option than the GermGuardian, so if you decide on this model, you won’t go wrong at all.
