Below mentioned are most used calculators in ambient or indoor air quality monitoring procedure.

Lets First see how to calculate mass concentration of the suspended Particulate..

 

Also we can calculate Total Volume of air sample in m3

 

 

Now we need to make correction for Volume of air sampled for STP by using below calculator

 

 

To measure Particulate matter we can use calculator shown below:

 

Air Quality Index (AQI) Categories

Here’s a simple classification based on AQI values:

• A: 0 – 50 (Good)
• B: 51 – 100 (Moderate)
• C: 101 – 150 (Unhealthy for Sensitive Groups)
• D: 151 – 200 (Unhealthy)
• E: 201 – 300 (Very Unhealthy)
• Above 300: Hazardous
