Overview

The LEVOIT Core 400S-P is a powerful air purifier designed for large rooms up to 1,733 square feet. Its layered filtration targets ultra-fine particles as small as 0.3 microns, while activated carbon helps reduce odors from everyday living. Real-time PM2.5 readings appear on the LCD screen and in the VeSync app, giving you a clear sense of your indoor air quality at a glance.

Smart sensing and quiet operation

AirSight Plus uses a laser-based sensor to monitor surrounding air and automatically adjust performance. In Sleep Mode, the unit dims the display and runs at a whisper-quiet 24 dB, ideal for bedrooms and night-time use. Auto Mode modulates fan speed to balance purification with comfort as air quality changes.
