Levoit Vital 100S-P

Levoit publishes 222 ft² at 4.8 air changes per hour and 1066 ft² at a single air change per hour.

The official specification gives a 23 to 52 dB range across the four fan speeds.

Auto Mode sets fan speed from the AirSight dust sensor, and the VeSync app adds Quiet Auto Mode and Efficient Auto Mode.

Sleep Mode runs below the low fan speed and turns the display off after 6 seconds.

2, 4 and 8 hour timers on the panel, and 1 to 24 hour timers in the VeSync app.

Display Lock button, held for 3 seconds, blocks the panel and can also be applied from the app while the unit is in standby.

Schedules with start and end times, fan speed or mode, created in the VeSync app.

The VeSync app shows real-time air quality plus the previous 4 weeks of history, and the remaining filter life percentage.

Levoit publishes the AHAM VERIFIDE seal for this model on its Amazon listings, alongside the verified 222 ft² at 4.8 air changes per hour figure.
