The Science of Air

Outdoors, naturally occurring ions are everywhere, and they continuously work to help clean the air. The concentration of these powerful ions, however, is much lower indoors.

Citadel Sciences delivers these air-purifying ions to the classroom. We use patented NPBI™ technology to reduce harmful airborne particles like viruses and bacteria by introducing ions into the air through your ventilation system — and we do this without introducing harmful ozone.

It's time to start going inside for some fresh air!

Clean Air, Clear Messaging

Air quality so clean you can see it thanks to Citadel’s IAQ sensors. The EPA recommends schools act to deliver clean air in the classrooms and communicate to let stakeholders understand and appreciate the actions taken.

Citadel Sciences delivers clean air and clear communications with every installation. Talking points for educational leaders and even media engagement all comes with a Citadel Sciences project. Communicating for impact — both internally and externally — is a key recommendation on the U.S. Environmental Protection Agency’s official Reference Guide for School Indoor Air Quality.

Citadel communications help leaders strengthen trust with the community and local media. We equip you to deliver clean air and inform teachers, parents and students on your efforts to ensure the air in your school is healthy, clean and consistently monitored.
