Mask/Filter/Valve Sizing

Feel like measuring?

You can also use a measurement if you want to be sure of the right size for you.  Measure from the bridge of your nose to just below your chin:

Measurement RZ Mask Size
3.5" - 4.0" Small / Medium
4" - 4.5" Large
4.5" and up Extra Large

 

Most of us know whether we have a “medium”, “large” or “x-large” face. That’s the easiest way to determine your size:

Face Size RZ Mask Size
Small / Medium Medium (we do not have a “small” mask size; our medium fits a small face.) 
Large Large
X-Large Extra Large
