You can now borrow a free CO2 Monitor, opens a new window from Halifax Public Libraries, just like you would borrow a book. This new addition to our Beyond Books, opens a new window collection helps users measure indoor air quality.
CO2 Monitors are simple, handheld tools that read carbon dioxide (CO2) levels in your spaces. High CO2 levels can mean that ventilation is insufficient for the number of people present. A reading can indicate if action is required to ensure a room is adequately ventilated and has access to clean, fresh air.
Battery-powered and portable, CO2 monitors are a great way to proactively keep an eye on air quality. Knowing the levels of CO2 present in your home or workspace can help lower your risk of airborne infection, and alert you to symptoms caused by poor ventilation—such as tiredness and headaches.
This collection has been made possible by funding and resource support from the Community Access to Ventilation (CAVI, opens a new window) Canadian CO2 Monitor Expansion Program. Halifax Public Libraries is grateful for this support.
Please note: The CO2 Monitors are not carbon monoxide detectors and are not life safety devices.
