Description

This state-of-the-art mask combines uncompromising safety with tactical versatility, empowering you to face the most challenging environments with absolute confidence.

  • Auto shut-off valve system enables safe filter changes while maintaining protection (accessory coming soon).

  • EN136:1998 Class 3 certification exceeds highest industry safety and performance standards.

C21™ Full Face Respirator Size Recommendations

Size No. Size in inches (chin to brow)
Size 1 5.19" – 5.51" (small)
Size 2 5.51" – 5.82" (medium) (universal most used)
Size 3 5.82" – 6.14" (large)


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.

    By far the best mask available to consumers

    We put this mask to the test at Survival Dispatch. Not only did it far exceed other masks for fit and finish and overall performance it’s one of very few masks that you can get a normal cheek weld on a rifle!

    The Final Piece of Our Family's Prep Puzzle – Thank You, MIRA Safety!

    The MIRA Safety C21 was the final piece of our family’s prep kit, and it exceeded expectations in both comfort and build quality. Their pre-sale support made choosing our first gas mask easy with helpful, detailed guidance. Highly recommend the C21 for anyone serious about preparedness.
