How Bad is The Air You’re Breathing?

We all want to breathe clean (hehe), fresh air. But how can we determine the quality of the air around us? That’s where the Air Quality Index (AQI) comes into play. It’s a valuable tool that helps us understand the level of air pollution in our surroundings. Today, we’ll take a closer look at the AQI featured on and explore a fascinating site that allows us to translate the AQI into an easily relatable concept—the number of cigarettes it simulates!

The Air Quality Index, commonly referred to as AQI, is a measurement that indicates how polluted the air is in a particular area. Developed by the Environmental Protection Agency (EPA), the AQI assigns a numerical value to air quality levels, ranging from 0 to 500. The higher the AQI value, the more polluted the air.

The AQI takes into account five major air pollutants regulated by the Clean Air Act: ground-level ozone, particulate matter (PM2.5 and PM10), carbon monoxide (CO), sulfur dioxide (SO2), and nitrogen dioxide (NO2). By monitoring these pollutants, the AQI provides a standardized method for assessing air quality and its potential health impacts.

When it comes to accessing real-time and reliable AQI data, is a go-to resource. I especially check it when I’m comparing inside air quality to outdoor air quality – if it’s the same or similar, we’re dealing with a house that will change with the weather (this is usually bad). The website is super simple (user-friendly for all ages) and allows a person to check the air quality in their area by simply entering a ZIP code or browsing through an interactive map. provides an accurate assessment of air pollution levels, helping you make informed decisions to protect your health and well-being.

While the AQI itself is a great indicator, it can sometimes be challenging to grasp the immediate impact of air pollution on our health. That’s where the intriguing concept of the cigarette equivalent comes in. There’s a GitHub website that takes the AQI value and calculates the number of cigarettes that would cause the same damage to our health.

This conversion helps put the potential risks of air pollution into perspective. For example, an AQI of 150 for a 24-hour period equates to smoking about 3 cigarettes a day. By comparing the AQI to cigarettes, we can better comprehend the short-term effects of air pollution on our bodies, making the connection between the quality of the air we breathe and our overall well-being.

Understanding the Air Quality Index can be an essential tool for safeguarding our health and the health of our planet. By relying on the information provided by, we can make informed decisions about outdoor activities, adjust our exercise routines, or take necessary precautions to protect ourselves from harmful pollutants.

The cigarette equivalent feature offered by the conversion website provides an innovative way to grasp the potential health risks associated with air pollution. By visualizing the impact of air quality in terms of cigarettes, we can better appreciate the importance of clean air and the urgent need for environmental stewardship.

So, the next time you check the AQI on, take a moment to reflect on the cigarette equivalent and what it means for your health. Let’s strive for cleaner air, not only for ourselves but also for guest in our homes and in our cities. And remember: if it’s bad outside and ALSO bad inside, you’ve got osme work to do.
