Why classroom air quality is important for children？

50% of Schools report poor indoor air quality. Poor indoor air quality can affect child’s health and ability to learn, as well as increase sick leave for both students and teachers. Studies show that classroom CO2 levels of 2500 ppm had much worse test scores than at 1000 ppm.

Use the GZAIR air quality meter to monitor and enhance the classroom’s air quality.
Not only can clean air in a classroom enhance focus and performance, but it also helps to stave off allergies and other health issues. As a result, adequate classroom ventilation is crucial, particularly during influenza season. Underventilated classrooms run the risk of becoming breeding grounds for the virus. You can precisely determine when and how long to ventilate with the help of a CO2 monitor.

Why measure CO2 in a classroom?

Carbon dioxide concentration (CO2) is now thought to be one of the main factors influencing indoor air quality in recent years. When the CO2 level in the classroom is too high, the kids can’t focus as well, perform badly, and feel sleepy. The classroom’s ventilation is gauged by the CO2 level. Therefore, the more CO2 there is in the atmosphere, the more contaminated the air is, and the higher the likelihood that kids will spread viruses to one another. Because of this, it’s critical to monitor the CO2 level so that you can ventilate as soon as needed.
Ascertain the upper limit of individuals in each classroom. The C02 value rises in proportion to the number of persons in the room. The maximum number of persons in a room can be inferred if the C02 value cannot be raised to the proper level.

Air quality monitoring solutions for classroom

We have several air quality monitoring solutions. Select one that fits your need.


Students Need Healthy Air To Learn

The management of a school community with many locations can monitor the data in real-time for each school, per room, and take appropriate action.

Why use GZAIR CO2 monitor for classroom

The GZAIR indoor air quality monitoring CO2 sensor is a plug-and-play device that connects to the cloud and gives you real-time data on the indoor environment’s pollution level. The GZAIR CO2 sensors provide not only the concentration of CO2 value in the air but also other parameters such as humidity, and temperature that affect the ambient environment around us.
GZAIR’s air quality monitoring portal gives you access to real-time and historical data with various charts and graphs for analysis. With Real-Time Alerts for sensors, you can configure high and low values and get an alert when the sensor value falls outside threshold levels.
The values can be read on the large screen which provides information about how healthy the air is. With some extra ventilation, you will immediately see the values improve.
Real-time data viewing allows the instructor and/or school administration to make quick decisions about things like improving ventilation or limiting the number of kids who are permitted entry into the classroom. Through the mobile application, students can also use Bluetooth to view the data of neighboring devices.
Where to place a CO2 monitor?
Place the CO2 monitor at least 1.5 meters away from a window or door. You can also put the CO2 monitor on the wall. In any case, make sure that you do not breathe directly into the device, as this will give distorted values. 
How many CO2 monitors should I install?
The GZAIR, for example, is suitable for a room up to approximately 50-meter square. If the room is larger, you can place several CO2 monitors, or take measurements at different places in the room.
With GZAIR monitoring solution, you may quickly and simply add indoor air quality (IAQ) sensors to any environment, which will help you minimize health hazards, enhance occupant performance, and maximize occupant experience. Assess the quality of the air using a number of important indicators, such as temperature, humidity, PM2.5, PM1.0, PM2.5, CO2, and pollen. Gain an understanding of the indoor air quality of your building’s spaces, such as the dining rooms, kitchens, meeting rooms, and offices, in order to maximize the HVAC and ventilation systems in your building and pinpoint areas where occupant comfort can be enhanced.
