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.

An apparatus for producing non-hydrated purified hydrogen peroxide gas (PHPG) from humid ambient air-comprising: an air distribution mechanism providing an airflow of said humid ambient air;a source of ultraviolet light; anda thin, air-permeable substrate structure having a titanium dioxide coate
1. An apparatus for producing non-hydrated purified hydrogen peroxide gas (PHPG) from humid ambient air-comprising: an air distribution mechanism providing an airflow of said humid ambient air;a source of ultraviolet light; anda thin, air-permeable substrate structure having a titanium dioxide coated surface, wherein said air flow is perpendicular to, and through, said air-permeable substrate structure 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 air-permeable substrate structure and into an environment when said apparatus is in operation. 2. The apparatus of claim 1, wherein said titanium dioxide comprises anatase, rutile, or a combination thereof. 3. The apparatus of claim 1, wherein said titanium dioxide coated surface is approximately 4 μm thick. 4. The apparatus of claim 1, further comprising a shell. 5. The apparatus of claim 4, wherein said shell is spherical, hemispherical, cubic, rectangular, a quarter cylinder, or a fanciful shape. 6. The apparatus of claim 4, wherein said shell is formed from ceramic, porcelain, or a polymer. 7. The apparatus of claim 4, wherein said shell further comprises a reflector. 8. The apparatus of claim 1, wherein said air-permeable substrate structure comprises fiberglass. 9. The apparatus of claim 4, wherein said air-permeable substrate structure is placed just inside, and parallel to the interior surface of said shell. 10. The apparatus of claim 1, wherein said titanium dioxide is applied to said air-permeable substrate structure surface as a paint. 11. The apparatus of claim 1, wherein said source of ultraviolet light produces a wavelength greater than 181 nanometers (nm), greater than 185 nm, or greater than 187 nm. 12. The apparatus of claim 1, wherein said source of ultraviolet light produces a wavelength between 182 nm and 254 nm. 13. The apparatus of claim 1, wherein said source of ultraviolet light comprises an ultraviolet light emitting diode (UV LED). 14. The apparatus of claim 1, wherein said air-permeable substrate structure further comprises a co-catalyst. 15. The apparatus of claim 14, wherein said co-catalyst covers less than five percent of said air-permeable substrate structure. 16. The apparatus of claim 15, wherein said co-catalyst is selected from platinum, silver, nickel, palladium, or phthalocyanine. 17. The apparatus of claim 1, further comprising a filter located upstream of said air-permeable substrate structure. 18. The apparatus of claim 17, 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. 19. The apparatus of claim 18, wherein said filter does not remove moisture from said humid ambient air. 20. The apparatus of claim 19, 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%. 21. An apparatus for producing non-hydrated purified hydrogen peroxide gas (PHPG) from humid ambient air comprising: an air distribution mechanism providing an airflow of said humid ambient air;a source of ultraviolet light producing ultraviolet light between 182 nm and 254 nm; anda thin, air-permeable substrate structure having a titanium dioxide coated surface, wherein said air flow is perpendicular to, and through, said air-permeable substrate structure 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 from said air-permeable substrate structure and into an environment when said apparatus is in operation.
