Host a PurpleAir sensor

You can sign up to host an air sensor.

What to know

Anyone can sign up to host an air sensor. 

No guarantees

Signing up does not guarantee that you'll receive an air sensor.

How it works

We'll let you know in about a week where you are on the list.

We give priority to people who live in:

  • Environmental justice areas
  • Areas where there is not another air sensor nearby

We distribute air sensors until we run out. More air sensors become available if:

  • A host leaves the program
  • We get funding to buy more 

You will remain on the list until you:

  • Receive an air sensor, or
  • Request to be removed from the list
