C21 Size Recommendations
| Size No. | Size in inches (chin to brow) |
| Size 1 | 5.19" – 5.51" (small) |

Determining your ideal respirator fit depends primarily on facial dimensions. While specialized measurement tools exist, we've simplified the selection process:
The mid-size option accommodates approximately 95% of users. Consider choosing small if you have a petite build (under 130 pounds) with narrow facial features. Those with broader faces or larger builds (exceeding 250 pounds) typically benefit from the large size.
Verify proper fit through the seal check: Block the intake valve and inhale deeply - the mask should create a tight seal against your face without air leakage.
Remember to separately purchase compatible filters and select your preferred size from the available options.
