School Air Quality Monitoring

Real-time air quality monitoring for classrooms, common spaces, and multi-building campuses across K-12 and higher education.

Aethair brings school air quality monitoring to K-12 districts and higher-education campuses, giving facilities and operations teams a continuous, real-time view of the conditions students and staff breathe every day. Aethair IAQ measures particulate matter, CO₂, VOCs, formaldehyde, temperature, humidity, and pressure in classrooms and shared spaces and reports into Environet, so one team can oversee a single building or an entire district from the same dashboard. For larger or outdoor areas, Aethair PRO adds indoor and outdoor monitoring and site-specific gas sensing. Set up alerts to be notified when a room moves outside its expected range, and use Aethair Reports to turn the readings into defensible documentation that school boards, administrators, staff, and regulators can use, which helps districts that must monitor and report on parameters like CO₂ meet those requirements. To learn the standards that apply and how monitoring pays for itself, read our article on indoor air quality in schools.

Why Monitoring Air Quality Matters in Schools and Universities

Classrooms are densely occupied, many buildings rely on HVAC that has aged well past its design life, and younger students are more sensitive to the conditions around them. Budgets are tight, so facilities teams need to know which rooms to prioritize rather than guess. Continuous monitoring answers that question with data.

Dense occupancy: Full classrooms raise CO₂ quickly, which can affect concentration.
Aging HVAC: Older ventilation drifts out of balance, and monitoring shows where.
Sensitive occupants: Children breathe more air relative to body weight than adults.
Where to start: See the standards and ROI case in our article on IAQ in schools .

What Aethair Monitors in Schools

Aethair IAQ measures nine parameters on one calibrated device, so a single monitor covers the pollutants and conditions that matter in occupied school spaces.

Particulate Matter

PM1, PM2.5, and PM10: the fine particles from outdoor smoke, traffic, and indoor activity that reach deep into the lungs.

Gases

CO₂ as a ventilation indicator, total VOCs (tVOC) from cleaning products and supplies, and formaldehyde from furnishings and building materials.

Environmental Conditions

Temperature, humidity, and barometric pressure, which affect comfort, focus, and how effectively a space ventilates.

Aethair IAQ covers occupied indoor rooms. For large open volumes like gymnasiums and auditoriums, spaces directly outside the building such as athletic fields and bus loops, or sites that need to track specific gases, Aethair PRO extends the same platform to indoor and outdoor monitoring and accepts hot-swappable gas sensor cartridges. And with Thiamis, you can integrate existing third-party sensors into the same platform, so you can monitor virtually any parameter your buildings already track.

How Aethair Works Across Your District

Install Aethair IAQ in classrooms, libraries, gyms, and cafeterias. Each device reports into Environet, where your team sees live air quality status and current conditions. View data history and trends for every room, and manage the whole deployment from one account, whether that is a single school or a multi-building district or campus. The platform extends beyond basic monitoring, with real-time text and email alerts, customizable air quality reports, and live public displays. Aethair is more than monitoring hardware. It is a full solution for understanding what is happening in your environment, reporting it to regulators, administrators, and staff, and helping teams act on defensible decisions backed by real data.

Monitoring by School Setting

A school is made up of very different spaces. Aethair covers all of them, so you can monitor everything from one easy-to-use platform.

Classrooms: The highest-occupancy rooms in any school, where CO₂ climbs through a lesson and temperature swings affect how well students focus. These are usually where districts start, with one Aethair IAQ per room.
Libraries, gyms, and cafeterias: Large shared spaces with occupancy that rises and falls through the day and ventilation needs of their own.
Large and outdoor spaces: Gymnasiums, auditoriums, athletic fields, and bus loops, where Aethair PRO adds indoor and outdoor coverage.
Higher-education campuses: Lecture halls, labs, and dorms across multiple buildings, monitored campus-wide from one account.

Why Monitoring Air Quality In Educational Spaces Pays Off

Healthy classrooms connect to outcomes school leaders already track. Monitoring gives facilities teams the data to act and the record to back it up. Read the full case, with sources, in our article's ROI section.

Attendance and funding

In many states, a share of school funding is tied to average daily attendance, so absences carry a direct budget cost. Monitoring helps you find the rooms that drive avoidable absences and address them before they add up.

Student and staff performance

Ventilation, CO₂, and temperature are linked to concentration, performance, and test results. Rooms that stay comfortable and well ventilated help students focus and teachers teach. Continuous data lets you hold conditions in that range, rather than finding out about a problem after a difficult day.

Energy and maintenance

Real data helps you right-size ventilation instead of running systems harder than needed, which can lower energy use. It also surfaces HVAC faults early, such as a unit that has drifted out of balance or a damper stuck closed, so maintenance can act before a small issue becomes a larger repair.

Air Quality Compliance and School Environmental Standards

Several frameworks shape how schools approach indoor air. The EPA's IAQ Tools for Schools program offers voluntary guidance, ASHRAE Standard 62.1 sets ventilation requirements for occupied buildings, and a growing number of states now require CO₂ monitoring in classrooms. Aethair gives you the continuous, time-stamped record to document where your spaces stand against these requirements and to support the reporting some of them call for. The platform also adapts to your needs, so you do not have to assemble a separate tool for every requirement. If your school or state has its own rules, custom alerts and reports can be set up to match them. For an explanation of each standard, see indoor air quality in schools.

Dashboards and Public Displays

Reports and alerts keep your facilities team informed. Aethair Dashboards do the same for everyone else. Drawing on live data from the Aethair Platform, a dashboard shows current air quality on a screen in a lobby, hallway, or classroom, or through a QR code that students, staff, and families can scan with their phones. For a school, that visibility is a practical way to show the community that conditions are being watched and to build confidence in the building.

School Air Quality Monitoring FAQ

How many air quality monitors does a school need?

It depends on building size and how granular you want the data. A common starting point is one Aethair IAQ per classroom or zone, plus shared spaces like the gym, library, and cafeteria, which may use an Aethair PRO. Some schools also use an Aethair PRO to monitor outdoor conditions, so they can improve HVAC performance while tracking the air directly outside their buildings on campus. Many districts begin with a pilot in a few buildings and expand once they see the data. We can help size a deployment during a demo.

Can we monitor a whole district from one dashboard?

Yes. Every Aethair device (Aethair IAQ, Aethair PRO, and Thiamis) reports into Environet , where facilities and leadership view every building and room from one account, with role-based access. The same setup works for a multi-building higher-education campus.

Does this support state CO₂ monitoring requirements?

Several states now require CO₂ monitoring in classrooms, and the specifics vary by state. Both Aethair IAQ and Aethair PRO measure CO₂ continuously and report it in Environet . That data can then be easily compiled in Aethair Reports , giving you a documented history to reference. For the standards that apply, see our article on indoor air quality in schools .

What does Aethair monitor in a classroom?

Depending on which device you place in the classroom, you can monitor different parameters. Aethair IAQ tracks Carbon Dioxide (CO₂), particulate matter (PM1, PM2.5, PM10), VOCs, formaldehyde, temperature, humidity, and pressure. Aethair PRO tracks particulate matter, temperature, pressure, humidity, sound, light, and up to 5 gases (depending on configuration) including CO₂, CO, VOCs, and more (download our full list of gas cartridges here ). CO₂ and PM2.5 are usually the most watched in schools, and one Aethair device can cover all of them, so you are not installing separate sensors to monitor one space.

How is this different from a consumer air quality monitor?

Consumer devices are not built for scale, and they introduce problems when used for facility-wide air quality management or documentation. Aethair devices are calibrated for accuracy and include a calibration certificate, their data feeds a central platform in Environet , and the platform includes tools to monitor live and historic data, produce real-time alerts, and generate audit-ready reports. For deployments beyond schools, see our commercial indoor air quality monitoring solution.

How quickly can a school get started?

Schools can easily start with a pilot program, installing devices in a few rooms and scaling when they decide to increase monitoring. After a demo, we help you choose where to place devices, ship calibrated Aethair IAQ and/or Aethair PRO units, and quickly have them reporting into Environet. You can expand to more rooms or buildings at any time; it’s as easy as turning on a new device that is associated with your account, truly a plug-and-play solution.
