The Levoit Core 300S and Core 400S started the evolution of the Levoit brand. Released in 2021, their improved controls, additional features, air quality sensors, and smart app control are what set them apart.
In this comparison, I will evaluate the performance, coverage, filtration technology, and additional features of these two air purifiers to determine which offers better value for money. But first, let’s compare their basic specifications!
The Levoit Core 300S is intended for small rooms of up to 219 sq. ft., while the Levoit Core 400S has a much more powerful motor that can effectively purify a room up to 403 sq. ft. Regarding filtration technology, both models use Levoit’s classic 3-in-1 filtration system, but the filter in the Core 400S is nearly double the size of the Core 300S filter.
When it comes to features, there isn’t much difference; both models contain the AirSight Plus air quality sensor and are compatible with the VeSync smart app. Overall, these air purifiers are innovative, high-quality ones and certainly worth considering.

Which One Does It Better?
To summarize, it’s challenging to single out one of these two air purifiers, especially because they are very similar, with the main differences lying in their size.
However, the Levoit Core 400S is somewhat more powerful. It offers a better power-to-cost ratio, uses a less expensive and long-lasting filter, and performed better in our tests. These factors are more than enough to declare the Levoit Core 400S the better buying option and my top recommendation.
Nevertheless, I wouldn’t overlook the Levoit Core 300S, particularly if you’re seeking an air purifier for smaller rooms under 219 sq. ft. in which this air purifier could be more cost-effective than the Core 400 if used correctly.
