Abstract
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.
Claims15
A method for microbial control and/or disinfection/remediation of an environment, the method comprising:
- (a) generating a gas comprising Purified Hydrogen Peroxide Gas (PHPG) that is substantially free of hydration, ozone, plasma species, and/or organic species;
- (b) directing the PHPG into the environment such that the hydrogen peroxide gas acts to provide microbial control and/or disinfection/remediation in the environment, both on surfaces and in the air.
A method for microbial control and/or disinfection/remediation of an environment, the method comprising:
- (a) exposing a metal, or metal oxide, catalyst to ultraviolet light in the presence of humid purified ambient air under conditions so as to form Purified Hydrogen Peroxide Gas (PHPG) that is substantially free of hydration, ozone, plasma species, and organic species;
- (b) directing the PHPG into the environment such that the hydrogen peroxide gas acts to provide infection control and/or disinfection/remediation in the environment, both on surfaces and in the air.
A diffuser apparatus for producing PHPG comprising:
- (a) a source of ultraviolet light;
- (b) a metal or metal oxide, catalyst substrate structure;
- and (d) an air distribution mechanism.
