GVS
Compact NIOSH-approved P100 half-mask with replaceable low-profile filters and a 4.65 oz complete weight.
The GVS Elipse SPR457 is the compact reusable P100 choice. The medium/large half-mask weighs 4.65 ounces with its two filters and uses low-profile replaceable SPR321 filter elements. GVS lists NIOSH approval TC-84A-6949 and a minimum 99.97 percent particulate efficiency.
Its small filter footprint is the reason to consider it for range use. The mask is designed to leave room for separate eye and ear protection, but that does not prove it will preserve a seal with every stock, optic height, or facial shape. Test the complete shooting position without letting the stock or glasses disturb the seal.
Like every tight-fitting respirator, it requires correct sizing, clean-shaven contact at the seal, and appropriate medical and fit-test steps. The P100 configuration is particulate protection, not universal protection against firing-emission gases or vapors.
Add the GVS Elipse P100 Respirator (M/L) to your build and see how it enhances your platform.
