Top 5 Questions I Get About BreezoMeter

BreezoMeter’s mission is to improve the health of billions of people across the world through real-time, actionable air quality data. We collect a huge amount of information about pollution, and develop advanced technologies to turn it into useful information.


But how do we actually do that?


If you’re reading this, you’re probably wondering that as well. So, without further ado, here are the 5 most common questions about BreezoMeter:


  • Question #1: How do you collect and calculate air quality data? Are you using sensors?


We don’t have any sensors of our own. Instead, to calculate our air quality data, we collect numerous layers of information from a variety of sources, like government monitoring stations, satellites, weather, and traffic. While there are millions of data points relating to the air we breathe, very few actually are willing and able to analyze it. We’ve built the right software to do this, using big data analytics, machine learning, dispersion modeling, and more.

The result? A single number between 0 and 100, which is a grade for how clean the air you’re breathing really is.

In another blog post, we’ve explained in detail why we don’t use low-cost sensors in our air quality analytics. If you’re interested, you can read it here. Or, quickly get up to speed on our technology in our brand new technology video: 



  • Question #2: Why is BreezoMeter sometimes very different from government data? Which should I trust?


Governments have been doing an amazing job monitoring our air. However, in a business context, government data can fall short in a few important ways.


First, it’s not completely real-time, as readings can sometimes be a few hours of delay. Second, government data isn’t hyperlocal: monitoring stations can get an accurate reading at their exact location, but air quality can be significantly different even just a few blocks away, so pulling out data from the nearest sensor is just wrong. Also, since countries measure air quality differently, global brands can’t rely on government data when launching products in multiple countries.

As mentioned, BreezoMeter gathers information from multiple sources, then analyzes pollution dispersion – so, the data you see is at your location, not where the sensor is. We also use our own proprietary pollution index – it’s 100% health oriented and standardized across the world.

  • Question #3: How do you ensure BreezoMeter is accurate?


We take a lot of pride in having the most accurate air quality information in the world. We have developed our own proprietary air quality dispersion models, and we’ve implemented a number of strict standards to ensure that we are trustworthy and reliable. As mentioned above, one of the most important factors is that we collect data from key sources: satellite, weather, traffic, and official monitoring stations.


Then, we use big data analytics – processing more than 680 gigabytes of information every hour – along with a dispersion model powered by machine learning techniques to get clean, reliable information. We also take important tests into account when crafting our algorithm. Here’s an example: we use the “leave-one-out” cross-validation method, which compares the measurements taken by one of our sources with our algorithm calculations for the same exact location, leaving the “real” source out. We then validate our accuracy through statistical analysis tests, which helps us refine our algorithm to the point where it’s just as reliable as the actual source. 


Accuracy is our number one priority, and we back this up with every enterprise client by committing to a strict service-level agreement and providing accuracy reports.

  • Question #4: How can businesses use air quality data?


By integrating with our API, businesses across the world are able to easily access our data and use it in interesting ways. Six main industries are getting a lot of value out of real-time air quality data: mobile & wearables, smart home, health & fitness, weather, automotive, and cosmetics & beauty.


For example, Dermalogica, the global skincare brand, uses BreezoMeter data to educate people on the effects that pollution has on our skin. Dyson uses it to monitor outdoor air quality for their line of air purifiers so people could know when to turn the purifier on or off. Cisco uses it to monitor air pollution across Paris. Ultimately, though, by making our data available in a simple, plug-and-play API, businesses across a wide range of industries have endless integration opportunities.

  • Question #5: How can individuals use air quality data?


Wherever you are, take a look around you: do you have any idea how polluted the air you’re breathing is? Do you know what’s in the air on your street, and how it changes over time? Air pollution is incredibly bad for our health, and the right data helps us avoid it and reduce its effects.


Our goal, from the start, has been to make air quality visible for everyone. Every day, over 50 million people across the world rely on BreezoMeter data to make simple decisions: should I go for a run? Should I take my kids to the park? Should I bike my normal route to work, or should I find a less polluted street? Should I buy a house here or there? A recent study found that BreezoMeter’s data actually changes our behaviour, proving that the right data, at the right time, can have significant effects on our health. That’s why leading brands like Dyson, Dermalogica, Motorola, Cisco, and many others have partnered with BreezoMeter, to engage their users and help them lead healthier lives.
