Borrow a Carbon Dioxide (CO2) Monitor

Carbon dioxide (CO2) monitors measure indoor air quality by checking the amount of carbon dioxide in the air. High indoor CO2 levels can cause tiredness, headaches, and other symptoms. 

You can borrow a CO2 monitor through the Library of Things collection as part of a public health and library initiative with a non-profit organization, Community Access to Ventilation Information (CAVI). Available for free with your library membership.

Please note: these devices are not carbon monoxide detectors and are not life safety devices.
