A device for generating and dispersing chlorine dioxide which includes a housing, at least one removeable tray having a plurality of compartments contained within an interior of the housing, and a fan in communication with the interior of the housing and the exterior of the housing for directing a current of chlorine dioxide gas that is generated from chemicals that are positioned within the removeable tray(s).

A system includes an airflow passage and an air purification element. The airflow passage is configured to confine a flow of air and direct the flow of air toward a space. The air purification element is positioned in the airflow passage and configured to produce a peroxide to oxidize contaminants in air flowing through the airflow passage. The air purification element includes a peroxide-generating structure and a matrix containing a peroxide-activating catalyst configured to activate peroxide produced. The air purification element is configured to produce the peroxide from a water vapor and oxygen in the air within the airflow passage when energized by an energy source, and the matrix is configured to allow the contaminants to contact peroxide activated by the peroxide-activating catalyst.

The present invention relates to a device for dispersing a volatile liquid comprising: a wick; a solid support; and a volatile liquid; wherein the wick is attached to the solid support; wherein the solid support is porous; and wherein the volatile liquid is contained within pores in the solid support. The invention also relates to methods of making such a device.

Examples are disclosed that relate to recirculating ventilation systems for cooking appliances. One example provides a cooking appliance ventilation system, comprising a ventilation duct comprising an inlet aperture configured to receive cooking exhaust, a fan configured to pull the cooking exhaust through the inlet aperture and the ventilation duct, an ozone source configured to introduce ozone into the ventilation duct; and one more ozone mitigation components positioned within the ventilation duct downstream of the ozone source.

The present disclosure relates to the field of malodour counteraction. More particularly, it concerns the use of volatile compositions to limit, decrease or eliminate the perception of fecal malodour. Such compositions include a malodour antagonist system associated with perfuming ingredients performing as malodour counteractant, in a combination that significantly reduces the perception of fecal malodour. Such compositions, their use in combination with delivery systems and their applications in consumer products are objects of the present disclosure.

Various implementations include a fluid treatment device. The device includes an outer tube, an inner tube, a plurality of blades, and a media. The outer tube includes an inner surface. The inner tube is coaxially disposed within the outer tube. An outer surface of the inner tube and the inner surface of the outer tube define an annulus that axially extends between the ends of the inner tube. The plurality of blades is disposed within the annulus. The plurality of blades is configured to alter a component of a flow direction of fluid flowing over the blades in a circumferential direction and/or a radial direction. The media is disposed within the inner tube. The inner tube defines a plurality of perforations extending between its outer surface and inner surface. The annulus defines an entire flow path of fluid flowing between the outer tube and the inner tube.

The present invention relates to a modular ozone-based disinfection system and method for treating air using configurable components tailored to specific applications. The system includes a purification configuration with an air circulation subsystem and an electrolytic ozone generator supplied by a tank configuration, which may comprise a fixed tank or a replaceable water cartridge. The generated ozone is mixed with airflow to create an oxidizing environment and is subsequently passed across a titanium dioxide-coated surface to reduce ozone levels before discharge. Optional modules include a dehumidifier configuration for extracting ambient moisture and a source water configuration for continuous supply. A controller manages system functions, including ozone generation, purification modes, and safety protocols. The method supports flexible operation, enabling safe, effective disinfection in occupied or confined spaces. The modular design allows for scalable deployment across diverse environments, including healthcare, food service, and public facilities.
