How VOC scale in ppb defined in Dyson Purifier? | Dyson Community
Skip to main content

Hello, would you dyson have something like chart below to explain what range of ppb considered when scale the VOCs level from 1-10+ in Dyson purifier? More specifically, what range of ppb considered as Good in dyson, what range of ppl consider as Fair, what range of ppb considered as Poor?

It would be very helpful in comparing data and accuracy. thank you
 

I have the same question .. my guess (based on data) from trial and error (with an air-q standing next to the purifier) is that roughly ...

  • ~ 500 pbb → switch from 0 to 1
  • > 550 pbb → switch from 1 to 2
  • > 600 pbb → switch from 2 to 3 

likely > 650pbb will switch into yellow .. I will add more data as I get to it (given new flooring that is causing headache) and current weather
