Features
Read full description

The PlasmaGuard app works with the PlasmaGuard whole-building air and surface purification system providing instant indoor air quality monitoring while proving the results. Use the app to track your office or home’s indoor air quality data in real-time and manage the air that you breathe. Quickly access the PlasmaGuard Sensors or easily control the PlasmaGuard Generator. The app allows you to view each Sensor installed, its particulate count, and the corresponding color. PlasmaGuard uses a color-coded scale to help you understand your air quality at a glance. Green indicates particle counts are below your target level, yellow suggests particles are moderately above target, and red signals PlasmaGuard to take action on your behalf to reduce airborne contaminants.
