Air Quality Monitoring Calculators: Essential Tools for Environmental Analysis

Accurate air quality monitoring is critical for assessing the health of our environment and ensuring compliance with regulatory standards. Our air quality monitoring calculators provide reliable, quick, and actionable insights for professionals, industries, and researchers. On this page, we offer calculators tailored to specific air quality metrics, including Suspended Particulate Matter Concentration, Total Volume of Air Sample, Volume of Air Sampled for STP, Air Quality Index (AQI), and Gas Concentration.

Air Quality Calculator India

India’s air quality is measured using PM2.5, PM10, NO₂, SO₂, CO, and Ozone levels. Use our AQI Calculator India to estimate the air quality index for different pollutants based on Indian standards.

National Air Quality Index (NAQI)

India’s National Air Quality Index (NAQI) is based on real-time pollution levels. It categorizes air quality into Good, Satisfactory, Moderate, Poor, Very Poor, and Severe. Our calculators help you determine your area’s AQI and understand the health impacts.

Available Calculators

1. Suspended Particulate Matter (SPM) Concentration Calculator

This calculator measures the concentration of suspended particulate matter (SPM) in the air, helping to assess air pollution levels. It uses input data such as the weight of particulate matter collected on a filter and the volume of air sampled.

2. Total Volume of Air Sample Calculator

This tool calculates the total volume of air sampled over a given period. It uses parameters such as the sampling time and flow rate, ensuring accuracy in air quality measurements.

3. Volume of Air Sampled for STP Calculator

This calculator adjusts the volume of air sampled to Standard Temperature and Pressure (STP) conditions. It accounts for temperature and pressure variations, ensuring consistency in air quality monitoring data.

4. Air Quality Index (AQI) Calculator

The AQI calculator converts pollutant concentrations into an easy-to-understand index, categorizing air quality levels from good to hazardous. It provides valuable insights for public awareness and regulatory compliance.

5. Gas Concentration Calculator

This tool calculates the concentration of gases like CO, SO₂, and NOx in the air, helping industries monitor emissions and address potential health risks.

6. Ventilation Rate Calculator

One important aspect of air quality monitoring, particularly for indoor environments, is ensuring proper ventilation. A Ventilation Rate Calculator can be a valuable addition to your toolkit.

• Purpose: Calculate the air exchange rate in a room or facility to maintain indoor air quality standards.
• Inputs Needed:
  • Room volume (m³)
  • Airflow rate (m³/hr)
• Formula:
  Ventilation Rate (Air Changes Per Hour, ACH) = Airflow Rate (m³/hr) / Room Volume (m³)​

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

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

AQI to Cigarette Equivalent Calculator – Know Your Air Pollution Exposure

Did you know that breathing polluted air can be as harmful as smoking cigarettes? Air Quality Index (AQI) is a measure of how clean or polluted the air is, but it’s often hard to relate AQI numbers to real-life health impacts.

This AQI to Cigarette Equivalent Calculator helps you understand how much air pollution you’re exposed to in terms of cigarettes smoked per day. Research suggests that an AQI of 150 is roughly equivalent to smoking 7 cigarettes per day, while higher AQI levels can be even more dangerous.

💨 Simply enter the AQI value for your city, and the calculator will estimate the number of cigarettes that breathing that air is equivalent to. This will help you take the right steps to protect yourself, such as using air purifiers, wearing masks, or staying indoors on high pollution days.

Try the calculator below to see how your city’s air compares! 🚭🌍
