The health-first way to run your schools.
Citadel puts world-class sensors in every classroom and turns the data into clear priorities, accountable vendors, smarter spending, and a story your community can trust.
Research Led, Data Driven, People Focused
Citadel was founded by leaders who protected the health of people in the nation’s most critical environments, including the White House. We bring that same standard of care to every classroom.

See every room
Kaiterra Sensedge Go monitors install in under a minute each, with no wiring, and can run entirely off your district network. Every classroom reports up to 17 environmental measurements around the clock, from CO2, particulates, VOCs, temperature, and humidity to occupancy and lighting.

Act with confidence
Citadel’s reports and expert guidance turn every reading into ranked, plain-language priorities: what to fix first, where to spend, and which vendors to hold accountable. Your district stays in control, and nothing gets bought on a guess.

Prove it and lead the story
Verify every improvement and vendor promise, track progress against your goals, and give your board and families a clear, calm record of results, with strategic communications support built in.
The four pillars of a healthy classroom
Every classroom monitor measures up to 17 conditions across air, thermal comfort, sound and light, tracks when each room is in use, and watches for mold risk and virus risk around the clock.

One investment. Returns across your district.
Healthy air is a science challenge. Earning trust for the work is a communications challenge. Citadel was built to do both, so every finding becomes a decision you can defend and a result your community can see.
