Fix The Mask is a mask fitter designed to improve the seal of common surgical face masks. So-called "medical grade" surgical masks which are certified as ASTM Level 2 or Level 3 have a material filtration efficiency >= 98% (at 0.1 μm). This means the material in the ASTM Level 2/3 surgical mask can be compared to that of common N95 masks — what is lacking is the fit of these masks. Fix The Mask is an effort to produce mask braces that seal surgical masks more closely to the face, increasing the efficacy of the mask in filtering potentially hazardous aerosols and droplets. Fix The Mask sells a pre-made "Essential Mask Brace" which has nose-fitting bristles as well as two bands that attach behind the head. Fix The Mask has instructions on how to make a DIY home mask brace from a rubber sheet at home as well as a simplified version that can be made using three rubber bands. In a study of aerosol transmission in a simulated classroom, the Fix The Mask Essential Mask Brace was found to dramatically improve mask filtration efficiacy: ..effective filtration efficiencies approaching the mask material filtration efficiency were achievable using simple mask fitters...this enables conditional infection probabilities < 0.001 (0.1%) or even < 0.0001 (0.01%) to be reached with the use of masks and mask fitters alone As of Feb. 13, 2021, the CDC recommends the use of a mask brace or fitter to improve the fit of common disposable masks. HistoryThe Fix The Mask was founded by Sabrina Paseman and Megan Duong. Sabrina Paseman is a Mechanical Engineer and previously worked as a Product Design Engineer at Apple, and Megan Duong was Global Head of Brand at Claris (Apple subsidiary). See also |
