Watch a video on making surgical masks as safe as N95 masks: Towards Surgical Mask Brace 2.0, a scalable, open source design by ex-Apple engineers

Why adapt surgical masks?

  • ‘Safety: Surgical masks have a government standard that regulates their filtration efficiency. They are regulated to meet ASTM standard F2100 which guarantees filtering 95% or more of COVID-19 sized particles.
  • ‘Accessible: Surgical masks are faster to manufacture and more readily available. Currently, of the 200 million masks China makes a day, only 600,000 are N95 standard masks. That means surgical masks can be made more than 300x faster than N95’s.’
