I have a new PurpleAir Flex Air Quality Monitor. It does not give readings for Ozone. See attached screenshot  
All other data types give readings.  
Is this a fault or a “feature”?  
Thanks  
Bill

Hi @Billylou, PurpleAir sensors do not currently measure ozone. More information on why this data layer appears on the PurpleAir map is available here: [The Ozone Data Layer on the PurpleAir Map](https://community.purpleair.com/t/the-ozone-data-layer-on-the-purpleair-map/973).
