Proven success with air quality monitoring

Sasho Manasov, PhD

Project Team Leader & Professor at International Slavic University

“Putting the power of air quality monitoring from institutions into the hands of communities is a game changer – every citizen, at any moment, can monitor air quality at any location in the city. Every politician must know that making decisions that improve air quality are standards that will protect us ourselves. Cooperation between local and central government is needed to determine an Action Plan for improving air quality. By implementing such a project in the municipality of Strumica, we have taken the first step (and the most important) towards such cooperation."

We work mainly with the local authorities for deploying the Node-S devices — with the local council. The community has been really helpful and has made a big difference. The majority of the Nodes are up on street lamps around the town.

"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."

"Air quality is a hidden issue in the sense that it's become so embedded in aspects of urban life in San Francisco. It can be a challenge for residents who have been living in the neighborhood for a long time to articulate what their air quality issues are. Some have just accepted it as a way of life.”
