Our take on the ST-100X Full Face Gas Mask Respirator

The ST-100X is a full-face respirator with a 40mm NATO filter thread, a five-point adjustable harness and a claimed 78% panoramic field of view. It weighs 445 g and is rated Class 2, with stated inward leakage of 0.04% and filter penetration of 0.03% or less. Its 40mm thread fits standard STANAG 4155 and EN 148-1 filters, so you are not locked into one brand. It is a general-purpose mask, not a certified CBRN or NIOSH-approved unit.

Questions and answers

Is the ST-100X safe for tear gas or smoke?
It can take a 40mm NATO particulate or combined filter, which helps with smoke and many riot-control agents. It is only Class 2 rated, so do not treat it as certified protection against chemical warfare agents.
Which filters fit the ST-100X?
Any filter with a 40mm NATO thread (STANAG 4155 or EN 148-1) screws on. Match the filter class to the hazard: particulate for dust and smoke, combined for gases.
How often should I replace the filter?
Replace a sealed filter before its shelf life ends, about five years for this mask's stock filters. Once opened, swap it when breathing gets hard or you smell the hazard.
Does it fit over glasses?
The full-face design leaves room for most glasses, but the five-point straps must seal around the temples. Test the seal before relying on it.
Is the ST-100X worth it over a half mask?
Choose it if you want eye protection and a wide view in one piece. A half mask with goggles is lighter and cheaper but leaves more of the face exposed.
What comes in the box?
Typically the mask, one 40mm filter and a carry bag. Check the listing, since some sellers ship the mask without a filter.
