My flex II, only one month old, is down to one sensor:

> **[Real-Time Air Quality Map | PurpleAir](https://map.purpleair.com/1/i/mAQI/a10/p604800/cC0#13.04/38.94261/-77.38393/-7.2)**

> Real time measurement of air quality on a public map. Useful to community scientists or air quality professionals alike, PurpleAir sensors are easy to install, requiring only a power outlet and WiFi.

I sent an email on monday the 17th to support but haven’t received a reply - trying here to figure how out to get in contact with support.

I get the particle counter is a consumable, but I think dead in a month is more likely a manufacturing defect than wear and tear.

No hitchhikers in mine, but PurpleAir did take care of me and made things right!

Likewise here - but I expect future inhabitation may be likely. I think people are wondering if some sort of screening could be used that would not affect the readings (or not much anyway).
