Improve fit of surgical masks

A good seal is critical to ensuring air flows through the filtering material, and not into the gaps around the edges.

Mask Fitter – Badger seal

Adding the Badger Seal to a 3-ply disposable mask reduces the effective particle penetration by typically 15x. DIY instructions here can be customized with head elastic, double elastic, or ear loops.

How does it create a good fit?

Patent pending Nose Cushions apply light pressure across your cheeks instead of placing it all directly on your nose. It’s the key difference between our flat rubber sheet template and the Essential Mask Brace, and truly changes the game.

There’s also a DIY option you can cut from a rubber sheet with scissors.

Do NOT take your mask off indoors

Dr Denise Dewald reminds us not to take masks off indoors, even if there is no one else around, because the virus persists in the air.
