Breathe99 is a startup social business headquartered in Minneapolis, Minnesota. Our mission is to make better public health products accessible to all. The company has been developing next-generation respiratory protection for over four years. As a Public Benefit Corporation (PBC), our goal is to not only design products that play a vital role in protecting human welfare, but to reimagine how public health tools are distributed in order to create the broadest possible impact on human health. Our flagship product is the B2 Mask -- an industrial-grade, reusable facemask that features changeable filters protecting you from 99.6%-98.3% of airborne particles, down to 0.1 micron, while significantly reducing filter waste and cost.
