Abstract
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.
Claims27
A chemical dispensing device, comprising (a) an absorbent matrix, (b) water absorbed onto said absorbent matrix and (c) an antimicrobial vapor generating material absorbed onto said absorbent matrix, (d) enclosed within a barrier system, wherein at least a portion of the barrier system is permeable to antimicrobial vapor and water vapor,
- wherein said chemical dispensing device releases water vapor and antimicrobial vapor when exposed to the atmosphere,
- wherein said antimicrobial vapor generating material is hydrogen peroxide, peracetic acid or a combination thereof.
The chemical dispensing device in aspect 1, wherein said absorbent matrix comprises an inorganic silica matrix selected from the group consisting of precipitated silica and fumed silica.
A method of both sanitizing and humidifying an enclosed or partially enclosed space comprising providing said space with an antimicrobial in vapor phase and water in vapor phase generated by passive evaporation of both an antimicrobial vapor and water vapor from an absorbent matrix enclosed within a barrier system, wherein at least a portion of the barrier system is permeable to antimicrobial vapor and water vapor,
- wherein said antimicrobial vapor generating material is hydrogen peroxide, peracetic acid or a combination thereof.
