BreezoMeter
BreezoMeter was born from a need to know the quality of the air we breathe, in real time. Our story began back in 2012, as we were looking for houses to live in. We needed to find pollution-free areas because of family health sensitivities, including asthma. As environmental engineers, we understood the connection between our health and the environment, and we refused to compromise on air quality.
