sensor discrepancy? | Dyson Community
Skip to main content

Do they have different sensors esp VOC? Or it’s something wrong with my unit ? In the same room the little guy is always 0 and the bigger one is always 1-4 . 
 

I know the little guy react to VOC but it’s not so sensitive . Thought ? 
do they use different sensors ? 
 

 

@catcheun Thanks for your post, the first thing I would do is clean out the sensor slots on your purifier  - this article has a visual guide on how to do that:

Hope this helps.
