The present invention relates to methods and devices for providing microbial control and/or disinfection/remediation of an environment. The methods generally comprise: generating a Purified Hydrogen Peroxide Gas (PHPG) that is substantially free of, e.g., hydration, ozone, plasma species, and/or organic species; and directing the gas comprising primarily PHPG into the environment such that the PHPG acts to provide microbial control and/or disinfection/remediation in the environment, preferably both on surfaces and in the air.

1. A diffuser apparatus for producing non-hydrated purified hydrogen peroxide gas (PHPG) from humid ambient air comprising: (a) an air distribution mechanism providing an airflow of said humid ambient air;(b) a source of ultraviolet light; and(c) a metal, or metal oxide catalyst on a thin, air-perme
1. A diffuser apparatus for producing non-hydrated purified hydrogen peroxide gas (PHPG) from humid ambient air comprising: (a) an air distribution mechanism providing an airflow of said humid ambient air;(b) a source of ultraviolet light; and(c) a metal, or metal oxide catalyst on a thin, air-permeable substrate structure having a surface,wherein said air flow is perpendicular to, and through, said surface and said humid ambient air has a residence time on said air-permeable substrate structure of less than a second,wherein said non-hydrated purified hydrogen peroxide gas comprises 0.015 ppm of ozone or less and is directed out of said diffuser apparatus and into an environment when said apparatus is in operation. 2. The apparatus of claim 1, wherein said air distribution mechanism is a fan. 3. The apparatus of claim 1, wherein said ultraviolet light source produces at least one range of wavelength between about 181 nanometers and about 254 nanometers. 4. The apparatus of claim 1, wherein said ultraviolet light produces more than one range of wavelength. 5. The apparatus of claim 1, wherein said metal or metal oxide catalyst is selected from the group consisting of titanium dioxide, copper, copper oxide, zinc, zinc oxide, iron, iron oxide, and mixtures thereof. 6. The apparatus of claim 5, wherein said metal or metal oxide catalyst further comprises a co-catalyst. 7. The apparatus of claim 6, wherein said co-catalyst is selected from platinum, silver, nickel, or palladium. 8. The apparatus of claim 1, wherein said thin, air-permeable substrate structure comprises fiberglass. 9. The apparatus of claim 1, further comprising a filter located upstream of said thin, air-permeable substrate structure. 10. The apparatus of claim 9, wherein said filter is an organic vapor filter, a dust filter, a high efficiency filter, a hydrophobic filter, an activated charcoal intake filter, or a combination thereof. 11. The apparatus of claim 1, wherein said air flow causes said thin, air-permeable substrate structure to be curved when said apparatus is under operation. 12. The apparatus of claim 1, wherein said humid ambient air has a relative humidity of between 10% and 99%, between 30% and 60%, between 35% and 40%, or between 56% and 59%. 13. The apparatus of claim 1, wherein said humid ambient air consisting essentially of non-hydrated purified hydrogen peroxide gas is directed through said thin, air-permeable substrate structure at a rate of up to 174.5 feet/min. 14. A photocatalytic reactor for producing non-hydrated purified hydrogen peroxide gas (PHPG) from humid ambient air comprising: (a) a housing;(b) an air distribution mechanism providing an airflow of said humid ambient air;(c) an intake filter;(d) a source of ultraviolet light; and(e) a metal, or metal oxide catalyst on a thin, air-permeable substrate structure having a surface,wherein said surface of said thin, air-permeable substrate structure is perpendicular to the direction of an air flow through said thin, air-permeable substrate structure; andwherein said humid ambient air has a residence time on said metal, or metal oxide catalyst of less than a second, and said non-hydrated purified hydrogen peroxide gas comprises 0.015 ppm or less ozone and is directed out of said photocatalytic reactor and into an environment when said photocatalytic reactor is in operation. 15. The photocatalytic reactor of claim 14, wherein said thin, air-permeable substrate structure comprises fiberglass. 16. The photocatalytic reactor of claim 14, wherein said intake filter is an organic vapor filter, a dust filter, a high efficiency filter, a hydrophobic filter, an activated charcoal filter, or a combination thereof. 17. The photocatalytic reactor of claim 14, wherein said air flow causes said thin, air-permeable substrate structure to be curved when said photocatalytic reactor is in operation. 18. The photocatalytic reactor of claim 14, wherein said air distribution mechanism is a fan. 19. The photocatalytic reactor of claim 14, wherein said metal or metal oxide catalyst is selected from the group consisting of titanium dioxide, copper, copper oxide, zinc, zinc oxide, iron, iron oxide, and mixtures thereof. 20. The photocatalytic reactor of claim 14, wherein said metal or metal oxide catalyst further comprises a co-catalyst selected from the group consisting of platinum, silver, nickel, palladium, and mixtures thereof.
