Abstract: A photocatalytic device comprising Manganese dioxide and Titanium dioxide coated housing, an ultraviolet light source disposed therein, and a plurality of multi-metallic photocatalytic structures, such as hydrated multi-metallic catalyst substrates, is adapted to be deployed in conjunction with the exchange air intake of a mini-split system. The photocatalytic device has (a) Manganese dioxide and Titanium dioxide coated reflector(s) that is/are positioned to reflect ultraviolet light onto the photocatalytic structures. The photocatalytic device may have at least one carbon fiber and/or needle type ionizer disposed in the housing. The photocatalytic device may also have at least one sensor and may be wirelessly coupled to a computing device or controller.

Abstract: A photocatalytic device has an ultraviolet light source and a plurality of photocatalytic structures, such as hydrated metallic catalyst surfaces. One or more catalyst substrates are adapted to support a hydroxyl radical reaction with ultraviolet light and water vapor that results in hydro peroxides and hydroxyl ions; an ultraviolet light source provides ultraviolet light to the catalyst substrates. The catalyst substrates comprising a hydrated multi-metallic catalyst having two or more elements or compounds selected from the group: Titanium dioxide, Titanium Platinum, Gold, Silver, Copper, Rhodium, Ruthenium, Lanthanum, Carbon, and Fluoride. In different embodiments, various combinations of these elements or compounds may be used in the catalyst, such as a combination of five or more of the elements or compounds.

Abstract: A photocatalytic device comprising an ultraviolet light source and a plurality of multi-metallic photocatalytic structures, such as hydrated quad-metallic catalyst surfaces, is mounted on a mini-split system. The photocatalytic device has curved reflectors that are positioned to reflect ultraviolet light against a face of the photocatalytic structures. The photocatalytic device has an exhaust deflection shield that directs airflow toward an intake of the mini-split or PTAC system.

Abstract: Systems and methods for the packaging of air treatment devices are shown and described. In some embodiments, a package may be configured to store an air treatment device. For example, the air treatment device may be an air filter, cleaner, purifier, or the like. The package may include a first lateral surface configured to accommodate a proximal end of the air treatment device and a second lateral surface configured to accommodate a distal end of the air treatment device. The package may further comprise a middle surface coupled between the first and second lateral surfaces. In some cases, at least a portion of the first or second lateral surfaces may include an opaque area. Moreover, at least a portion of the middle surface may include a transparent or translucent area configured to reveal at least a portion of the air treatment device.

Abstract: Photocatalytic devices are described. In some embodiments, a photocatalytic device may include a cylindrical housing having an inlet opening and an outlet opening; one or more catalyst substrates disposed within the cylindrical housing and adapted to support a hydroxyl radical reaction with ultraviolet light and water vapor that results in hydro peroxides and hydroxyl ions; an ultraviolet light source disposed within the cylindrical housing and adapted to provide the ultraviolet light to the one or more catalyst substrates; and a fan disposed within the cylindrical housing and adapted to cause air to enter the cylindrical housing via the inlet opening, circulate through the one or more catalyst substrates within the cylindrical housing, and exit the cylindrical housing via the outlet opening.

Abstract: A photocatalytic device has an ultraviolet light source and a plurality of photocatalytic structures, such as hydrated quad-metallic catalyst surfaces. The photocatalytic device has curved reflectors that are positioned to reflect ultraviolet light against a face of the photocatalytic structures. The curved reflectors are shaped to minimize the distance traveled by the ultraviolet light between the light source and the photocatalytic structure. The curved reflector is further shaped to direct reflected ultraviolet against the surface of the photocatalytic structure in a perpendicular direction.
