Our Verdict
Levoit Core 400S
Levoit Eleva 300X
The Levoit Core 400S is better than the Levoit Eleva 300X. The Core 400S has a significantly higher clean air delivery rate, making it a more effective option for larger spaces. The Core 400S also maintains its performance advantage at lower, quieter fan speeds, so it'll do a better job when running overnight in larger bedrooms. That said, it's worth noting that the Eleva 300X is considerably quieter across its fan speed range, and is smaller too.
