Bring your students back to school safely

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. Students and parents breathe easier knowing that your school has a plan for protecting student health.

Superintendent/Principal, Pope Valley USD 
“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 from exposure to unhealthy levels of air pollution.

"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.
