Corsi-Rosenthal Construction Central

As positive COVID case numbers continued to rise in New York City and beyond, an idea to improve air quality in our classrooms was brought to the PTA and SLT by teachers and parents. We have since built inexpensive, effective air filters called Corsi-Rosenthal (CR) boxes for each classroom at both school sites as well as shared rooms and the cafeteria.

If you are interested in finding out more about these DIY air filters, here are some references to check out:

Tests have shown that the clean air provided by the Corsi-Rosenthal boxes is high volume and effective at eliminating the tiny aerosol particles that carry the virus. While each CR box is individually not very expensive, we built almost 50 CR boxes to cover classrooms at both sites, the cafeteria, and other spaces occupied by many people throughout the day.
