What tools are used to measure air quality?
The Short Answer: Air quality is measured with the Air Quality Index, or AQI. The AQI works like a thermometer that runs from 0 to 500 degrees. However, instead of showing changes in the temperature, the AQI is a way of showing changes in the amount of pollution in the air.
How can I test the air quality of myself?
Here are three simple tests you can run to check the air quality in your home:
- Dampen a sterile sponge with a rinse solution and wipe a section of the air filter or supply duct vent.
- Place the sponge in a rinse container and pour more solution over it.
- Shake the rinse container and pour the contents into a sample cup.
What are 3 sources where you can track air quality?
Emissions Data – EPA keeps track of the amount of pollution that comes from a variety of sources such as vehicles, power plants, and industries. The emissions data reported to EPA by state environmental agencies can be an actual reading taken at a source or an estimate made using a mathematical calculation.
How do you measure air quality particulates?
How Does the Particulate Matter Sensor Work?
- A laser diode shines a light beam through a cavity.
- A fan draws air into the cavity with fine dust particles suspended in the air.
- As the laser beam shines through the air, the dust particles deflect or scatter some of the laser light.
How does air quality monitoring work?
How Does an Air Quality Monitor Work? Air quality monitors are fitted with multiple sensors made to detect different types of pollutants. An electrochemical sensor detects oxygen levels and the presence of toxic gas by reducing it through an electrode and measuring its concentration.
How do you measure air particles?
The simplest way to measure the mass concentration of particles in the air is to pull ambient air through a filter using a pump. The measured pump flow multiplied with the total sampling time provides the sampled volume of air.
How do you measure particulate matter in air at home?
The PM sensor operates through the following method:
- A laser diode shines a light beam through a cavity.
- A fan draws air into the cavity with fine dust particles suspended in the air.
- As the laser beam shines through the air, the dust particles deflect or scatter some of the laser light.
How can I find out what the air quality is like?
Each day, you can find out what the air quality is like by checking the Air Quality Index (AQI) for where you live. The AQI tells you when high levels of air pollution are predicted for the day. You can use that information to plan for safe and healthy physical activity. * Sensitive groups include people who have asthma, heart disease, or COPD.

Do I need an air quality monitor for my home?
If you’re experiencing symptoms you suspect are related to indoor air quality, getting an air quality monitor is an inexpensive way to pinpoint the problem. By monitoring levels of indoor air pollution, you can take steps to get fresh air back into your home, and hopefully, a little peace of mind with it.
How can I check the air quality index without an app?
If you would prefer not to download an app just to check the air quality index, then there are several different websites that you can check. On these sites, you’ll need to give the website permission to use your location, or just input information like your zip code, city, or state for a general scope.
