Levoit Core 300S vs Eleva 300X

The Levoit Eleva 300X is a slight improvement over the Levoit Core 300S. The Eleva 300X features a display that shows real-time particle levels, providing a more detailed assessment of air quality at a glance. It uses a different filter design with separate primary and activated carbon layers, so you don't need to replace both stages if only one is worn down. In terms of performance, however, the Eleva 300X provides only a marginal bump, with a slightly higher max particle filtration rate, superior performance at lower fan speeds, and a small reduction in operating noise.
