Levoit 400S Smart True HEPA Air Purifier
Description Designed as the bigger sister to the Levoit Core 300S, the Core 400S Smart True HEPA Air Purifier powerfully purifies the air with enough coverage for the entire home. Even though the Core 400s is larger and more effective, built-in QuietKEAP technology maintains noise levels as quiet as 24dB while also extending the life of the motor. Improved 360° Vortex Air technology speeds up circulation to filter out more pollutants, and a Laser Particle Sensor continually detects current air quality so that the air purifier can automatically adjust its settings to match. Users can control their air purifier remotely by connecting it to the VeSync app on their smartphone, where they can also set schedules and timers, monitor air quality and view remaining filter life.
