BTN is low-cost face mask that reduces the risk of COVID-19 transmission. Its simple construction provides equitable access to those most in need, regardless of location or income.
People living in low-income countries have limited access to masks. The single-use BTN mask is an innovative, easy-to-use design that can be mass-produced almost anywhere using common, low-cost materials and conveniently distributed to those in need.
