Who should buy the Levoit Core 300?
The Levoit Core 300 is our recommendation for: Bedrooms and small living rooms. If your room is much larger than 219 sq ft you'll struggle to hit 4 air changes per hour - step up to the Core 400S or Core 600S. If you mainly care about smart features rather than coverage, the Core 300S is the cheapest Levoit with Alexa support.
