Air quality is divided into two main areas- Indoor and Outdoor

Indoor Air Quality (IAQ) - Wikipedia Article

Relative Humidity (RH %) - Wikipedia Article

Volatile Organic Compounds (VOC ppb) - Wikipedia Article

Carbon Dioxide (CO2 ppm) - Wikipedia Article

For humans indoor RH below 35% feels uncomfortably dry; above 65% feels uncomfortably humid

For ease of understanding the iZone summarise the overall IAQ from the worst reading of the VOC and CO2 sensors. The categories and levels are as follows:

Each of the states and territories of Australia is responsible for monitoring air quality and publishing data in accordance with the national NEPM standards

Each state and territory publishes air quality data for individual monitoring locations, and most states and territories publish air quality indexes for each monitoring location

Across Australia, a consistent approach is taken with air quality indexes, using a simple linear scale where 100 represents the maximum concentration standard for each pollutant, as set by the NEPM

These maximum concentration standards are:

The air quality index (AQI) for an individual location is simply the highest of the air quality index values for each pollutant being monitored at that location

 AQI bands, with health advice for each:

Monitoring Tab: Scroll down to the monitoring tab on the home screen
