Levoit Core® 400S Smart Air Purifier

A larger smart purifier for living rooms and open areas, with a laser sensor that shows live PM2.5 and adjusts the fan automatically. Manage it on the unit or from the VeSync app.

• AirSight Plus laser sensor with a live PM2.5 reading and colour air-quality rings
• Auto Mode adjusts fan speed to air quality; the app adds Quiet and Efficient auto settings
• Three-stage filter with an ARC-formula carbon layer aimed at cooking and pet odours
• Main filter rated to capture 99.97% of airborne particles 0.1–0.3 µm, per Levoit
• Four fan speeds including Turbo, plus Sleep Mode
• VeSync app control, schedules and filter-life tracking; works with Alexa and Google Assistant

In dusty or smoky conditions, expect to replace the filter toward the shorter end of the recommended interval.
