    What does the PM2.5 indicator in my Philips Air Purifier mean?

    Published on 28 June 2023
    PM2.5 is a scale for measuring real time air quality. Its values vary from 0 to 500. 

    The PM2.5 indication is connected to your Philips Air Purifier’s air quality light ring/bar to inform you in real time about the quality of the ambient air.

    The different colors indicate the following: 

    * Blue: good 

    * Blue-Violet: fair 

    * Red-Purple: unhealthy 

    * Red: very unhealthy
