The present invention provides for a system for disinfecting air circulated in an HVAC system. The system includes at least one spray ring forming a continuous loop surrounding an outer surface of HVAC ductwork. The system further includes a plurality of spray nozzles connecting to each of the spray rings in the at least one spray ring, wherein each nozzle extends through an aperture in the HVAC ductwork, wherein a space between each nozzle and each aperture is sealed by a rubber gasket.

The invention is a system and method for the initial and on-going disinfection of pathogens from building surfaces and plumbing fixtures. The disclosed system and method can be particularly useful in bathrooms to disinfect the drains of sinks, toilets, bathtubs, and other standing water sources that act as persistent reservoirs of deadly pathogens. The disclosed system and method include a disinfecting chemical storage or disinfecting chemical generation unit, a control module, a conduit configured to pump or convey the disinfecting fluid to a surface of the plumbing fixture, an attachment configured to attach a portion of the distribution structure piping, and at least two separate openings in the piping or other conduit.

A cartridge that is releasably connectable with a housing of a microfluidic delivery device is provided. The cartridge has a reservoir for containing a fluid composition and a microfluidic die in fluid communication with the reservoir. The microfluidic die is configured to dispense substantially all of the fluid composition in a horizontal direction or downward direction relative to horizontal. The cartridge also includes an air flow channel disposed below the reservoir. The air flow channel extends from a fan to an air outlet. The air flow channel comprises a first region disposed adjacent to a fan, a second region disposed adjacent to the air outlet, and a third region joining the first and second regions. At least the second region is angled upward to the air outlet, relative to horizontal.

A benefit agent delivery system can deliver benefit agents on demand. The benefit agent delivery system comprises a first electrode layer, a microcell layer comprising a plurality of microcells, and a porous second electrode layer. Each microcell of the plurality of microcells are filled with a liquid mixture comprising reverse micelles in a hydrophobic liquid that are formed from a polar liquid, an ionic surfactant, and a benefit agent. Application of an electric field on the microcell layer affects the rate of release of the benefit agent through the porous second electrode layer.

[Object] To propose a novel and improved fragrance material holding member and fragrance providing device that can improve persistence of a fragrance material while avoiding an increase in the size of the device. [Solution] Provided is a fragrance material holding member including: an airflow passage through which air supplied from an airflow source passes, the airflow passage being provided to penetrate the fragrance material holding member; and a holding space that branches from the airflow passage and holds a fragrance material.

A compact diffuser integrates an atomizer and droplet separator into a surrounding sleeve, threadable to a bottle neck as an assembly. The assembly fits into a base, housing a motor and air pump, sealing the sleeve to a silo in the housing. Controls set time span of intermittent operation, intervening delay, and volumetric flow rate. The assembly pops into (and out of) the top end of a silo in the base, registering (aligning) circumferentially and axially to seal an air path from the pump to the atomizer. Access for applying force to the bottom of the assembly facilitates popping out the assembly when empty, or to simply change scent by changing out the assembly. Entire assemblies may be stored to simplify exchange and reduce chances for spills from reservoirs.
