UNC Hospital team test our masks with excellent results
Updated: Sep 12, 2020
Our masks tested far better than most DIY masks. See below for the comparative results of medical grade respirators and surgical masks and our DIY masks with filter inserts. Our results in filtering out 50 nanometer particles were slightly superior to medical grade surgical masks that tie around the head and far better than medical grade surgical masks that loop around the ear. No other DIY masks scored nearly as well!
