Don’t just take our word for it – leading organizations across North America are already using our air quality monitoring equipment to guard against wildfire smoke. Here are a few examples of how our customers have deployed Clarity for wildfire monitoring:
"We wanted a network that would get real-time data out to the public immediately and show air quality changes in real-time — which we had been unable to do with our network of reference-grade equipment alone."
"Clarity’s innovative technology has significantly improved our understanding of urban air pollution and its impact on public health and the environment. The system’s accuracy, reliability, and user-friendly interface have proven to be extremely effective tools for both decision-makers and the public. It provides real‑time, accessible data that enables informed policy development and empowers citizens with the knowledge to take action. This initiative has been highly appreciated by local authorities, environmental specialists, and the general public.”
"Clarity was our first-choice air quality monitoring provider for several reasons. We enjoyed working with the Clarity team - they are highly knowledgeable and always responsive. The Node-S devices themselves are also incredibly resilient, which was especially important for us when deploying the monitors in emergency conditions during the wildfire events this past year."
"We couldn’t have done it with any other air quality monitoring solution. With their unique ability to operate off-grid, Clarity’s Node-S provided the ability to site our air quality monitors in the locations that mattered most to community members in Richmond. The data are reliable, real-time, and hyperlocal, and our network is now being used as a blueprint for AB 617, a landmark regulation that empowers communities to take control of air pollution."
"In 2020, we installed 50 sensors in the city of Bishkek. Since the Clarity Node-S sensors installed in Bishkek are small, we installed them all over the city. We placed some of them near roads, some in residential areas, and some in social facilities. Thanks to the Global SIM Card which is incorporated in the sensors, we get the data directly to our system which allows us to visualize the data. The data is ready for analysis.”
Having a larger network of sensors where we have a better resolution of where air pollution is worse or better will be beneficial in allowing us to change behaviors, educate people more, or do all sorts of things to improve the health of those people

Environmental leaders don’t just need air monitoring equipment; they need a reliable air quality measurement system that delivers actionable insights, supports public transparency, and scales across entire cities. When it comes to monitoring air pollution and ensuring environmental safety, cities don’t just buy sensors—they invest in quality assurance for trustworthy data.
Here are a few reasons why Clarity air pollution measurement equipment is chosen for urban air quality monitoring by cities worldwide.
Our outdoor air quality sensors are built to withstand heat, cold, humidity, storms, and long-term field exposure. With robust QA/QC and automated calibration workflows, agencies receive trustworthy data for PM₂.₅, PM₁₀, NO₂, NOx, ozone, CO, meteorological parameters, and other air pollutants.
Clarity’s Sensing-as-a-Service approach combines the Clarity Node-S, flexible Add-On Modules, cloud analytics, and expert support, creating a seamless environmental monitoring system for agencies that need both accuracy and ease of deployment.
Cities such as Chicago, London, Los Angeles, Manila, Philadelphia, Perth, Washington D.C. and Yerevan rely on Clarity’s air quality monitoring instrumentation to measure air quality at the city scale and engage communities in reducing air pollution exposure.
Clarity provides more than just air quality measurement: we provide a full-stack air quality monitoring system designed for both community engagement and regulatory support. Our Add-on Services turn raw air pollution data into recommended actions to drive action across local authorities, schools, communities, and industry alike.
Clarity dramatically reduces the total cost of ownership for citywide air quality measurement, unlocking higher-resolution air quality data that delivers better insights for a fraction of the cost of traditional reference monitors.
Our OpenMap platform enables agencies to share ambient monitoring data directly with residents, schools, and decision-makers, building trust and supporting environmental justice initiatives.
Clarity’s outdoor air quality measurement system complements reference-grade air quality monitoring stations; it does not replace them. Clarity enhances spatial resolution, fills coverage gaps, and supports hyperlocal ambient monitoring at scale. Reference monitors are still needed for regulatory reporting and compliance.
A few of the things that set Clarity apart are our global scale, solar-friendly hardware, low maintenance, accuracy validated across hundreds of collocations, fast deployment, strong customer service, and a complete air quality monitoring system that includes much more than just sensors.
Unlike consumer-grade air quality monitors, our platform is built for large-scale deployments in tough environmental conditions and supports integration into enterprise systems. It’s tailored for air pollution measurement projects at a large scale, such as municipal ambient air quality monitoring networks.
We calibrate, validate, and quality-assure all data, ensuring you get reliable air quality measurements for your city. We partner with high-quality instrument makers for Add-On Modules, deploy remote calibration, use quality-control protocols, and provide analytics to flag drift or failure. This ensures trustworthy air quality data.
Local authorities, environmental agencies, school districts, tribal air quality departments, AQMDs, industrial sites, community groups, and research institutions across 85+ countries use Clarity air quality monitoring. If your priority is accurate ambient air quality measurement or actionable air quality monitoring for decision-making, we’re the partner of choice.
We’ve deployed networks as small as a few air quality sensors up to hundreds of air quality monitoring devices in urban, rural, and industrial environments across 250 + cities and 85 + countries. For example, for Breathe London, we deployed 400+ devices across 63 km², and Chicago has deployed more than 200 Clarity Node-S air quality sensors across the city.
