With the YESAIR Indoor Air Quality Monitor you have the power in your hands to know the level of air quality inside the building and respond accordingly.


Navigating through the COVID 19 pandemic has brought to the forelight the importance of maintaining healthy indoor air quality. There is no sensor that can directly detect the COVID 19 virus in the air or on surfaces. However monitoring other common effects such as carbon dioxide levels, relative humidity, temperatures, particles in the air, etc. is the first component that helps ensure the air quality inside the building remains safe and healthy. The second component is the ventilation system that exhausts old contaminated air and brings in new clean air. The number of people inside the building will cause fluctuations in the amount of CO2, the RH and temperature levels and the amount of particles floating in the air. It is important that the ventilation system settings are adequate and the system itself is working properly especially during high occupancy times.

The YESAIR is purpose built to monitor & collect data on indoor air quality, aiding in the treatment of on-going respiratory issues and providing the information upon which decisions can be made and actions taken to keep the air we breathe indoors as healthy as possible.
