Levoit Core 300 vs Core 300S

On paper, the Levoit Core 300S should be a straightforward upgrade of the standard Levoit Core 300, delivering the same performance with the addition of a particle sensor and Wi-Fi connectivity, allowing for automatic fan speed adjustment and full remote operation through its VeSync companion app. In reality however, things are a little more complicated; the 300S features a power-optimized motor that draws less power than the one in the older 300. While this would seem to be a net benefit, this actually results in a vastly lower clean air delivery rate.
