The PurpleAir Flex is based on the popular PurpleAir Classic, with the circuit board of the Zen.

The PurpleAir Flex is perfect for residential, commercial, or industrial users looking to collect real-time PM2.5 data from a tough, inconspicuous sensor. Connect it to WiFi to view that data on the PurpleAir Real-Time Map. An LED light displays AQI information at a glance, and a modular design provides easy access to internals.

This sensor contains an SD logger for offline data collection but does not come with a microSD card. You can get one here!

• North American and EU (Type A and Type C) you will order the USB-C + Micro Adaptor
• International plug type British and Australasian (Type G and Type I) you will order the Micro USB option
