You can now borrow a CO2 Monitor from the library!
Ventilation and carbon dioxide (CO2) measurements are two of many precautions that can be taken to protect yourself and your community from airborne infections. Comparing indoor CO2 readings to the baseline outdoors can give us an idea of how well a space is ventilated with fresh air from outdoors.
Please note: These devices are not carbon monoxide detectors and are not life safety devices. For more information on carbon monoxide alarms, please see the Fire Safety Education page.

| Tips for using the CO2 Monitors |
- Take the device outdoors in an open area away from crowds. After a few minutes, the reading should be between 400 to 450 ppm. This means it is properly calibrated. If it is not properly calibrated, follow the instructions in the user manual.
- Always take readings at least two metres away from people's faces or your readings may be artificially high.
- Readings should be performed when the space is occupied. If you expect 30 people in the room, you'll want to take a reading with 30 people present.
- You may notice the readings stay steady, rise continuously or cycle from higher to lower values. These patterns provide hints to how the space is ventilated and may guide your troubleshooting to improve ventilation in the space.
