Proven success with air quality monitoring

Eddie Ahn

Executive Director, Brightline Defense

"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."

Tomislav Andreev

Head of Environmental sector for the city of Strumica, North Macedonia

“With Clarity's hyperlocal network, we can begin to provide a more complete picture of how air pollution is occurring in a given micro region, and what preventive actions we need to take to minimize exposure. We can also measure the effectiveness of each activity taken by measuring concentrations BEFORE and AFTER that activity. This encourages us to think about policies that we want to change. It raises citizen awareness and creates a narrative that influences positive change. We need to know what the air is like NOW AND IMMEDIATELY, at each MICRO location, to react IMMEDIATELY, and to sanction those who are disrupting our health, the future of our youngest, and the future of our country. Every citizen of the municipality of Strumica has a strong ally in such innovative technology."

Lecturer in Physical Chemistry, University College Cork

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.

Representative, Sac Metro Air District

"A program is only half the program when you have the data, and the other half is what information the community will have so that they know what actions to take to protect themselves, to protect their family, their employees, and just their community members in general."
