Bring your students back safely with air quality monitoring

Breathe easier with an air quality action plan

Schools are facing more days with unhealthy air quality than ever before, negatively impacting academic performance and increasing absences. Three in five US children are worried about the impact of air pollution on their health. Students and parents breathe easier knowing that your school has a plan for protecting student health.

Reduce absences and improve academic performance by managing air quality

Studies have found that a single day of unhealthy air quality can more than double absences. Absences come at a cost to both schools, and students' families. By monitoring air quality and minimizing student exposure to air pollution, schools can minimize air quality-related absences.
Exposure to outdoor air pollution can inhibit cognitive development and negatively impact academic achievement. Studies have found air pollution levels to be a statistically significant predictors of student performance. The higher the exposure to air pollution, the lower the test scores.
Air quality can change rapidly, making it important to have access to real-time air quality data when making operational decisions. Our air quality monitors can produce accurate air quality readings in as frequently as 5 minute intervals - ensuring you make the right decisions for student health.

Know Your Air Network

On Earth Day, LAUSD announced the Know Your Air Network in partnership with Clarity and the Coalition for Clean Air. This first-of-its-kind ambient air monitoring network provides real-time monitoring across more than 200 school campuses, yielding reliable, local air quality data for over 700,000 students.

“We chose Clarity because they provided up-to-date, local, scientifically-backed, and relevant data to make decisions about whether to keep students inside. Because of the geography and demographics in our county, the official air monitoring stations are about an hour away with hills in between, providing irrelevant data. We would have poor air quality and the official stations would be cleared; or the official stations would show heavy particulate levels and we would have clean air."

Know when to switch to indoor activities

On days when air quality is very poor, schools are recommended to enforce indoor activity schedules. Monitoring AQI levels at your school and following outdoor physical activity guidelines is one of the most effective ways to protect students.

"Having the sensor on site is great for our school and a nice service to offer our surrounding community. Our device went in about 3 years ago and is working great! It is so important for us to know our air quality. Whenever it hits unhealthy levels, we keep our students inside. The data is available right on my phone, so I can check it ahead of recess and make a real-time decision on whether to send students outside or keep them on an indoor activity schedule when air quality is over the threshold.
