Air quality is measured by the below metrics
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 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:
RATING / PPB
VOC
Great
0-60 ppb
VOC levels are normal
Good
61-200 ppb
VOC levels are moderate. Opening windows, doors or turn on ventilation fans to increase the outdoor air exchange will help to reduce the VOC levels
Fair
201-2030 ppb
VOC levels are elevated. Opening windows, doors or turn on ventilation fans to increase the outdoor air exchange will help to reduce the VOC levels
Poor
above 2030 ppb
VOC levels are high. The most important sources of VOCs include cigarette smoke, vehicle related emissions, building renovations, solvents, house hold cleaning products and pesticides. It is strongly recommended that windows, doors are opened or ventilation fans are started to increase the outdoor air exchange to reduce the VOC levels
RATING / PPM
CO2
Great
200-600 ppm
Co2 levels are low and healthy
Good
601-900 ppm
Co2 levels are acceptable
Fair
901-1400 ppm
Co2 levels are high and may cause drowsiness acceptable. Opening windows, doors or turn on ventilation fans to increase the outdoor air exchange will help to reduce the Co2 levels
Poor
above 1400 ppm
Co2 levels are excessive and extended exposure to these levels may cause health issues. Opening windows, doors or turn on ventilation fans to increase the outdoor air exchange will help to reduce the Co2 levels
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:
Pollutant | Averaging period | Maximum concentration standard |
Carbon monoxide | 8 hours | 9ppm |
Nitrogen dioxide | 1 hour | 0.12ppm |
Ozone
| 1 hour | 0.10ppm |
4 hours | 0.08ppm | |
Sulphur dioxide
| 1 hour | 0.20ppm |
1 day | 0.08ppm | |
1 year | 0.02ppm | |
Lead | 1 year | 0.50 μg/m3 |
PM 10
| 1 day | 50 μg/m3 |
1 year | 25 μg/m3 | |
PM 2.5
| 1 day | 25 μg/m3 |
1 year | 8 μg/m3 |
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:
AQI | Description | Health advice |
0–33 | Very Good | Enjoy activities |
34–66 | Good | Enjoy activities |
67–99 | Fair | People unusually sensitive to air pollution: Plan strenuous outdoor activities when air quality is better |
100–149 | Poor | Sensitive Groups: Cut back or reschedule strenuous outdoor activities |
150–200 | Very Poor | Sensitive groups: Avoid strenuous outdoor activities. Everyone: Cut back or reschedule strenuous outdoor activities |
200+ | Hazardous | Sensitive groups: Avoid all outdoor physical activities. Everyone: Significantly cut back on outdoor physical activities |
