Devices and methods for provided both an antimicrobial vapor such as hydrogen peroxide and/or peracetic acid and water vapor in an enclosed or partially enclosed space are described. The device and method provided is for the reduction or elimination of microbes from air and surfaces in contact with air within an enclosed or partially enclosed space using hydrogen peroxide or peracetic acid in the vapor phase and also provide for humidity from water vapor. The device and method are directed towards a release of an antimicrobial vapor and water vapor through a permeable container/barrier containing a matrix into which water and an antimicrobial vapor producing material are absorbed.
