Abstract: An apparatus for sanitizing air includes a reactor, for generating reactive oxygen species from oxygen in air received in the reactor to be sanitized. The reactor includes at least one reaction chamber. The apparatus further includes a reactor clamp configured to support the at least one reaction chamber.

Abstract: An in-duct apparatus for sanitizing air includes a reaction unit, configured to be mounted in an air duct, for generating reactive oxygen species from oxygen in air received in the reaction unit to be sanitized. Airborne contaminants in the received air are substantially neutralized by the generated reactive oxygen species before the air is discharged from the reaction unit.

Abstract: An apparatus (and method) for sanitizing air includes a generating unit that generates reactive oxygen species and ozone from oxygen in air, received by the generating unit, to be sanitized, and a cancellation unit or conversion filter that cancels at least a portion of the ozone before the air is returned to an area to be sanitized.

Abstract: An apparatus for sanitizing air including a reaction unit for generating reactive oxygen species from oxygen in the air received in the reaction unit to be sanitized, wherein airborne contaminants in the air to be sanitized are neutralized by the generated concentration of reactive oxygen species before the air is discharged from the reaction unit. The reaction unit may further generate ozone from the oxygen in the air and the generated ozone is discharged with the air from the reaction unit to sanitize surfaces in the environment into which the sanitized air is discharged.
