Step 7: Adjust For Seal & Comfort

With either style strap attached, pull the assembly down over your head

with facepiece in front and the strap behind your head (think of pulling

down Ski Goggles, but lower – under your nose). Make sure it covers your

mouth while cradling the bottom your nose. 󰾬

Adjust the strap length for comfort and fit. The facepiece should be

comfortable (no need to make it tight) while sealing securely but gently so

that all breath flows through the hexagonal holes in the transparent

facepiece. 󰾬

Once adjusted, you can take it off and put it back on anytime without

additional adjustments.
