CO2 Monitors

CO2 Monitors

CO2 monitors are now available at MPL. Exposure to too much CO2 can have adverse effects such as fatigue, headaches, and increase the risk of airborne infections. The CO2 monitors are designed to measure the indoor air quality and identify poorly ventilated spaces. With your library card, you can check out a monitor for 7 days at a time with 1 renewal (if no holds). You can place a hold on it online and pick it up at the Service Desk at the branch. When you are done using them, please return it at the Service Desk.

Concerned about the air quality in your home? You can now borrow a CO2 monitor from MPL.  Each monitor is designed to measure the indoor air quality and identify poorly ventilated spaces. This will help you determine if you need to take steps to improve the air quality in your space to lower the risk of airborne infections.

Each Kit will include:

    1. One CO2 Monitor
    2. Quick Start Guide
    3. AA Batteries
