50 Cities, Inc. improves human health outcomes by developing and adapting technologies that clean, purify and disinfect indoor air. Our studies indicate, even in carefully disinfected modern facilities, indoor spaces often contain unrecognized dangerous populations of airborne pathogens and allergens not directly addressed by protective measures until after infections have occurred. Because of the emergence of COVID-19, and after careful analyses, we have adapted our business model to demonstrate how our innovative technology can be remarkably fast, safe and effective at the earliest stages of emergent hyper-local contagions and widespread pandemics.
