US Centers for Disease Control and Prevention (CDC) recommend: "Use a mask fitter or brace over a disposable mask or a cloth mask to prevent air from leaking around the edges of the mask." Improve How Your Mask Protects You | CDC
For this purpose, LM mask brace is developed by two US university researchers. It is well-engineered to provide a seal between a surgical mask and your face. As per the testing results of an FDA-recognized lab, with this brace, the air inside a standard surgical mask was found to be averaging 30 times cleaner than without it. It also reduces glasses fog. The brace is 100% made of medical (skin-contact) grade silicone. It is adjustable at all 4 corners, and reusable for at least 1 year.
  • Seal the edge of a standard surgical mask---- LM mask brace provides a protective seal between a standard surgical mask and your face. It also reduces glasses fog.
  • 30 Times More Cleaner Air to Breathe---- Due to the seal of LM brace, the number of particles inside a standard surgical mask has been further reduced by 30 times on average. These are the testing results, obtained by an FDA-recognized lab using particles with sizes between 0.02 and 1 micron.
  • Reusable for at least 1 Year---- Wash and sterilize it with water and alcohol before each use. It is autoclavable for over 200 times.
  • 100% made of medical (skin-contact) grade silicone---- LM brace is skin-friendly, and has a soft feel.
  • Locally Adjustable at all 4 corners of brace---- The two head straps can be locally adjusted at all 4 corners of the brace, to better fit face. 
  • Snug and Comfortable Fit----(i) Local adjustability of straps, (ii) well-engineered nose portion, and (iii) flexible material enable this mask brace to have a snug and comfortable fit, with minimum pressure on the nose and cheeks of a wearer.
  • Color----Transparent
  • Size---- One size for most adult men or women. It is used together with a standard surgical mask or thin cloth mask. Not intended for use with a thick cloth mask.
