Join the movement to get clean air in schools!

90% of schools are under-ventilated. Poor indoor air quality in schools impacts student attendance, learning, and health. Teachers are also impacted, with sick days affecting their ability to work and teach, and making them more susceptible to long term illness.

We can fix this with Corsi-Rosenthal (CR) Boxes - highly efficient air cleaning devices that deliver clean air at a cost of just $4 per student.

A donation of $100 will provide clean air for an entire classroom for a whole a year!
A donation of $5,000 will provide clean air for an entire school for a whole year!

CR Boxes are:

highly effective
affordable
simple to build in less than 30 minutes
a great STEM project for students (can be turned into a science lesson)
efficient at removing other respiratory irritants from the air, such as smoke particles

We have already provided equipment to build thousands of CR boxes in schools and community centers. We need your help to continue in the fight for clean air for all and make clean air even more accessible in our communities.

Our goal of $25,000 will provide clean indoor air to over 250 classrooms, bringing cleaner air to thousands of students and teachers.

Your donation gets us closer to our goal of ensuring that all students and staff have access to the clean air they need to thrive. Any amount gets us closer to our goal. Donate today and share with your friends, family and colleagues!
