Our detachable Air Quality Sensor connects to our free iOS and Android app to measure your air quality in 3 different ways.

1. Particulate Matter 2.5 (PM2.5)

Measures the concentration of particles 2.5 microns in diameter or smaller, in the air you breathe.

2. Air Quality Index (AQI)

A number between 0 (good) to 500 (bad) that shows how polluted the air around you is.

3. Wynd Air Score

We combine multiple data points from PM2.5 & AQI to create our own proprietary Wynd Score from 0-100.
