Method and an integrated device for an area decontamination process

A method of decontaminating a space with a biocide comprising the steps of:

• a. providing a biocide effective for killing a pathogen, wherein said biocide is hydrogen peroxide and wherein said biocide is provided in the form of a mist, a vapor or a condensed vapor, wherein the amount of said biocide delivered into the space is not more than 30% greater than the minimum concentration required to kill the pathogen and not greater than 2.46 g/m3 and wherein said biocide is delivered into the space at a rate of at least 0.1 g/min/m3;
• b. allowing said biocide to reside in the space for a residence time sufficient to effect at least a 4-log kill, but not longer than 15 minutes;
• and,
• c. reducing said biocide to a level of not more than 1.0 ppm by using an aeration process,
• and wherein the residence time is defined as the difference between time the biocide begins to be introduced into the space and the time the aeration process is initiated.
