Thrive throughout the changing seasons with the Levoit OasisMist 450S Smart Humidifier. Choose between warm and cool mist settings, and enjoy continuous mist for up to 45 hours in a 215–430 sq ft room before refilling the top-fill tank. Equipped with humidity sensors, Auto Mode can sense changes in your room’s humidity and automatically adjust the mist level to maintain your target humidity percentage. Control settings remotely with the free VeSync app, as well as create schedules, connect to third-party voice assistants, and receive real-time notifications. You can even add your favorite essential oils to the built-in aroma box for a touch of light fragrance. Finally, cycle between optional light colors to create a custom glow.
