PurpleAir Flex - Air Quality Monitor

Excellent device

Easy to setup, and accurate. Really helpful for judging when to go for outdoors cardio. The double sensor provides internal validity. Interesting to realize the patterns of air pollution around my neighbourhood.

Needs its own app otherwise very awkward to see your data

The PurpleAir map doesn't load where I last searched so I have to swipe and enlarge the map to click on my dot. If I want temperature or humidity data, there are several more clicks needed. I had to purchase an app to get push notifications for hazardous conditions, which is another feature I thought the PA app would have. But there's no PA app. Very disappointing that something sold as providing this data is so incredibly awkward to use. Seems inappropriate for domestic users.

Easy to install and works well

The sensor is easy to install and connected to the network w/o any issues.
