This tool developed by researchers at Colorado State University, Portland State University, & Illinois Institute of Technology has been a very helpful tool for Bowerbird Energy when evaluating the efficacy of air purification systems being offered in the marketplace. In the wake of COVID-19, our staff has encountered many manufacturers and distributors fraudulently marketing their products. This tool, along with our internal procedures, mitigates the risk of our clients becoming victim to fraudulent claims and ineffective air purification units.
