An air freshener dispenser assembly includes a dispensing unit for containing a chemical fragrance. The dispensing unit releases a measured amount of the chemical fragrance when the dispensing unit is turned on. In this way the dispensing unit can enhance odors associated with an area proximate the dispensing unit. A pair of switches is each of the switches is coupled the dispensing unit and each of the switches is turned on when a user sits on the seat. The dispensing unit is turned on when the switches are turned on. In this way the dispensing unit reduces odors associated with the user employing the toilet.

A ventilation system for removal of aerosols including bacteria and viruses such as the COVID-19 Coronavirus, and airborne debris from dental/medical operatories is provided. This ventilation system is comprised of (1) a stationary hood, secured at a specific distance above a patient that pulls contaminated air from the operatory, (2) ducting that carries the contaminated air away from the operatory, (3) a UV Ozonator that treats the air and cleans it of viral and bacterial aerosols and airborne debris before (4) expelling it to the outside through a specified length of terminal duct. The combination of certain embodiments in this invention create an effective means of aerosol and airborne debris removal in dental/medical operatories or other indoor spaces.

A system for active and automated cleaning of interior surfaces and air within an enclosed space. The system is generally composed of an air cleaning sub-system, a surface cleaning sub-system, and an interface sub-system that is hands-free to prevent contacting fomites and spreading disease. The air cleaning sub-system employs a fan mounted above the enclosed space. In an elevator environment, this can easily be installed to avoid structural crosshead beams. Air is then pushed down through a flexible boot which includes a HEPA filter, pushing filtered and ionized air down past individual's heads and exhausted through the bottom of the enclosed space, such as the toe kick vents in an elevator environment. In this way, the air reaching the individuals within the space is clean, fresh, and has not made contact with other individuals within the space prior to being inhaled.

A deodorization module including a housing having a suction port and a discharge port formed therein, a fan disposed between the suction port and the discharge port, a photocatalytic filter disposed between the suction port and the fan, a light source module including a substrate and an ultraviolet light source and configured to irradiate the photocatalytic filter with ultraviolet light, and an ion generator disposed between the fan and the discharge port.

The present invention is directed to a digital aroma system that provides a scented air on demand to various devices in various forms and user held devices including: remote controls, video game controllers and mobile computing devices. Dry fragrance infused substrates are contained in fragrance cartridges that are removably mounted in a cassette that is connected to a manifold that has airway passages that are connected to fans or pumps that are controlled by a computer processor. In response to a fragrance control signal or a fragrance trigger, the processor can selectively direct scented air having a specified fragrance to a system user.

An apparatus for treating air includes a housing with an air inlet and an air outlet, the housing enclosing an air treatment zone and an ozone removal zone, wherein the ozone removal zone is positioned downstream of the air treatment zone with respect to a flow direction of the air being treated, an ultraviolet (UV) light source in the air treatment zone configured to generate ozone from the air, wherein the UV light from the UV light source and the ozone generated by the UV light source treat the air in the air treatment zone, catalyst in the ozone removal zone that removes at least a portion of the ozone generated by the UV light source, and an air mover positioned near the air outlet configured to draw the air through the air inlet into the air treatment zone from outside the housing.

A volatile material dispensing system includes a frame having a front face and a rear face. A first magnetic element is disposed on the frame. A reservoir containing a volatile material is provided. A second magnetic element is disposed on the reservoir.

An aromatic shower sachet is a personal hygiene and aromatherapy device used to diffuse pleasant and therapeutic scents throughout a shower area when exposed to water or steam. The aromatic shower sachet utilizes a permeable enclosure containing a quantity of aromatic compound, a quantity of absorbent starch, a quantity of reactive base, and a quantity of acid catalyst homogenously mixed into water-reactive mixture. The water-reactive mixture is retained within the permeable enclosure such that water or water vapor may penetrate the permeable enclosure. The water reacts on-contact with the water-reactive mixture, releasing fragrances through the permeable enclosure.

An UV air and surface disinfection apparatus comprises a housing with moveable or adjustable walls, an air chamber defining a passageway operable to receive air and direct the air in a predetermined direction, a plurality of ultraviolet light sources supported by the housing and arranged in a predetermined pattern around the air chamber such that, when the plurality of ultraviolet light sources are energized, the plurality of ultraviolet light sources project ultraviolet radiation outward to facilitate sterilizing air as it moves through the air chamber and when the walls are open, the ultraviolet radiation is further projected outwardly to an environment or area outside of the housing to facilitate sterilizing surfaces.

A concealed air sanitization device is disclosed. The concealed air sanitization device comprises a housing having an interior chamber, and an air inlet and outlet communicating between the interior chamber and an exterior environment. The concealed air sanitization device further comprises an air circulation unit configured to draw air into the interior chamber through the air inlet, one or more ultraviolet light sources disposed within the interior chamber, and one or more sensors configured to detect human presence proximate the air sanitization device. The concealed air sanitization device further comprises a processor configured to receive signals from the sensors in response to detection of human presence, and activate the air circulation unit and ultraviolet light sources in response to the detection to draw air from the exterior environment into the interior chamber and emit ultraviolet light to the air.
