Clean Air, Better Schools

Board-ready baseline in days. Rapid, wireless sensors map every room—beyond CO₂ to PM2.5, VOCs, and Virus Risk—delivering a clear, disruption-free risk profile so you can rank fixes and control spend.

• Stronger funding posture. Defensible evidence to justify every dollar and unlock grants/blocked funds—turning air quality from an unfunded problem into a financed improvement.

• Phased execution—off your plate. Citadel acts as the owner’s advocate, translating data into a sequenced plan and coordinating all vendors from diagnosis to resolution for verified results without adding to workload.

• Compliance without surprises. We track emerging standards (e.g., ASHRAE 241/44) and local codes, turning mandate risk into a strategic advantage with simple, ongoing proof of performance.

• Returns you can amplify. Higher attendance (ADA) via reduced chronic absenteeism, lower staff turnover through healthier workplaces, and community trust that supports enrollment.

Step 1: Gain Control

We’ve partnered with Airthings because their enterprise-grade, wireless sensors deploy in days and stream trustworthy, room-by-room air data into an intuitive dashboard.

Using Airthings sensors, Citadel delivers an objective baseline that surfaces hotspots, ranks priorities, and arms you with defensible evidence for grants, budgets, and board approvals.

Within weeks you receive a board-ready baseline report, live alerts, and a prioritized game plan—so every next move is fact-based, sequenced for ROI, and tailored to your schools.

The EPA Recommendation for Schools:
Clean Air & Clear Communication

Citadel supports your communications team in an awareness campaign focused on building and strengthening trust within the community.

We do this by helping you inform teachers, parents, and students about your efforts to ensure the air in your school is healthy, clean, and consistently monitored.
