Levoit Vital 100S
The Core 300's smarter sibling. For roughly $15 more, the Vital 100S adds a real-time PM2.5 readout on the display, VeSync app scheduling, and a washable pre-filter that cuts down on replacement-filter waste — while keeping the same 25 dB sleep-mode noise floor.

Our Verdict
For about $15 more than the plain Core 300, it adds a real-time air quality readout and a washable pre-filter that lowers long-term running cost — more capability per dollar than the model above it.

Alternatives to Consider
Levoit Core 300
Levoit
The default recommendation for a nightstand-sized bedroom purifier. The Core 300 pairs a genuine H13 HEPA filter with a dedicated Sleep Mode that drops fan noise to 24 dB and dims the display — quiet enough to run all night next to the bed without being a distraction.
Levoit Core 300S
Levoit
The same quiet Core 300 hardware wrapped in full smart-home control. The 300S adds WiFi, Alexa and Google Assistant voice commands, and app-based scheduling, so the purifier can ramp down automatically at bedtime and back up in the morning without touching a button.
Winix A230
Winix
A true HEPA alternative to the Levoit lineup with a built-in air quality sensor and Auto Mode that reacts to what it detects overnight. Its PlasmaWave odor feature can be switched off entirely, which matters for anyone sensitive to ionizer-style purifiers in a closed bedroom.
GermGuardian AC4825E
GermGuardian
The lowest entry price in this lineup, and the pick for buyers who mainly want a HEPA filter running quietly on low overnight. Its 22-inch tower adds an optional UV-C sanitizer stage that the other purifiers here don't offer, though it lacks a dedicated ultra-quiet sleep setting.
