B2 Mask provides a high-quality alternative for Personal Protective Equipment (PPE) to the public that helps address shortages for healthcare workers.
Cloth masks flooded the market due to shortages, but are academically proven, in randomized control trials, to be considerably less effective than medical-standard masks (MacIntyre et al, 2015)

The B2 Mask: a durable, reusable mask that provides superior protection with highly efficient, changeable, low-waste filters, that can be available at scale to users.
A platform of donations: establishing an impact-oriented distribution system that attempts to correct inequalities of access to respiratory protection for a range of public health purposes.
