Clean air is a right, not a privilege. For children whose lungs are still growing, every breath of polluted air can leave lasting harm. I spoke with Professor Juliana Jalaludin, Head of the Research Project on Air Quality and Health Impact at Universiti Putra Malaysia, about why preschools have become the focus of her work. An AirGradient ONE monitor is installed in a preschool classroom to track the air children breathe every day.| AirGradient Air Quality Monitors on AirGradient
A common misconception about plants is that they clean or purify the air around us. The reason for this are several studies like the NASA Clean Air Study which tested various plants to find possible ways of cleaning the air in sealed environments like space stations. Even though plants can improve indoor air quality their effect is relatively small compared to other methods like air purifiers and filters. In this context, plants or potted plants simply means any indoor plants that are grown i...| AirGradient Air Quality Monitors on AirGradient
When we first set out to create a low-cost air quality monitoring solution as part of the United Nations Development Programme (UNDP) Open Innovation Challenge, the initial problem statement was clear: design a toolkit that resource-limited communities could afford. However, it quickly became evident that cost wasn’t the only barrier, and affordable hardware alone wouldn’t be enough to ensure the project’s success. Providing sensors, no matter how affordable or accurate, is of limited u...| AirGradient Air Quality Monitors on AirGradient
When the United Nations Development Programme (UNDP) launched an Open Innovation Challenge to design a low-cost hyperlocal air quality monitoring toolkit, we at AirGradient knew it was a mission we wanted to be part of. Addressing global challenges like air pollution requires solutions to be scalable, accessible, and grounded in practical application. That’s why, together with the UNDP Global Centre for Technology, Innovation and Sustainable Development, we developed a toolkit with one clea...| AirGradient Air Quality Monitors on AirGradient
Growing up mixed race, there was always a noticeable difference between the two countries I’m from. In the Netherlands, public spaces felt more orderly. There are bike paths, benches, and parks in almost every corner. In the Philippines, the streets are livelier with noise and movement. You’ll usually see children playing basketball, street food vendors, and tricycles passing by from time to time. At first, those were the differences that stood out to me: the everyday scenes that made bot...| AirGradient Air Quality Monitors on AirGradient
How do we know that something isn’t right with the air we breathe? Perhaps by the sound of coughing, the sight of a hazy skyline, or the smell of smoke lingering in the air. Although air pollution remains mostly invisible, modern technology can remedy this by turning what is an intangible threat into concrete data. However, collecting data is only half the battle. What truly matters is how that data is used, and that depends on the people on the ground.| AirGradient Air Quality Monitors on AirGradient
If you’ve ever looked at purchasing an air quality monitor, you might have noticed something odd: while air quality monitors with PM2.5 sensors are everywhere and relatively affordable (starting at under $50), monitors that measure nitrogen dioxide (NO₂) are surprisingly rare and expensive, often costing over $1,000. Well, there’s an interesting technical story behind this price gap that reveals just how challenging it is to accurately measure certain air pollutants.| AirGradient Air Quality Monitors on AirGradient
Every month, a group of dedicated runners from Lagos, Nigeria, lace up their shoes and run the same city marathon route they always have. At first glance, it may look like they’re chasing personal records, but there’s a bigger motivation driving their stride.

Not all particulate matter is created equal. Two environments can show the same PM2.5 value on a monitor, yet be composed of completely different types of particles. One might be mostly fine soot, the other made up of coarse dust. To a typical user, these differences are invisible, but to the sensor inside your monitor, they matter a great deal. At AirGradient, we believe understanding these nuances is essential, especially when it comes to evaluating how accurate or meaningful an air quality...| Articles on AirGradient

Below article was written by Kazbek Tursun during his internship in our science team. He digged deep into our massive co-location data and saw some significant deviations just based on the type of reference stations used. What he uncovers raises some profound questions on how we evaluate data from reference stations. The results from reference instruments using the BAM method are actually quite shocking. These expensive “gold standard” instruments show such poor hourly correlation with lo...| Articles on AirGradient

When we talk about air pollution, we often focus on the present. What’s the air like today? Are PM2.5 levels high? Is it safe to go for a walk, or should we stay indoors? During a recent conversation with Beatriz and Danny from the World Resources Institute (WRI), I was reminded that the real opportunity lies in looking ahead. What if we could see pollution coming before it hits? That’s where air quality forecasting comes in. And for many cities in the Global South, it’s not just helpfu...| Articles on AirGradient

This is the driving force behind the development of the AirGradient-UNDP Air Quality Toolkit: to provide communit...| Articles on AirGradient
Introduction In September 2024, we published an article about PM2.5 and how the EPA correction algorithm improves the accuracy of AirGradient’s monitors. We observed that our sensors, the PMS5003 from Plantower, systematically overestimate PM2.5 when concentrations are above 10 to 20 µg/m3. The algorithm from the EPA ( equation 4) does a great job of bringing down the high readings. Meanwhile, we have implemented the algorithm for our outdoor and indoor monitors, as explained here. Today...| Articles on AirGradient

Can you really trust the air quality data you rely on? Prompted by a lack of transparency within the field of air quality monitoring, that’s a question we set out to learn more about a couple of months ago. In a field in which public health and environmental research and policies are directly based on data from air quality monitors, how much of an impact do ‘black box’ monitors and sensors have on muddying our results?| Articles on AirGradient
