The present invention relates to the field of firefighter facial masks. More specifically, the present invention relates to a firefighter respirator mask device that is preferably comprised of a body, a facial covering over an opening of an SCBA mask, a fastening mechanism and a filter. The body of the device preferably resembles an ovular shape, or any shape that sufficiently covers the hole left over the mouth of an SCBA mask when not attached to an oxygenated hose, normally present under hazardous conditions. The device is comprised of color-changing technology that allows the facial mask to turn colors in response to pathogenic exposure, indicating to the user that it is no longer sterile. In this manner, the device can be applied to any firefighter or industrial worker requiring the use of an SCBA without risk of possible pathogenic exposure when not attached to an oxygenated hose.
