A plume cleaning system for a toilet is integrated with a toilet. In one example, a plume cleaner assembly adjacent to a toilet seat is independently removable with respect to the toilet seat. The plume cleaner assembly may include a plume cleaner, apertures, and a fan positioned to draw plume air through the plurality of apertures for treatment by the plume cleaner and expel the treated plume air out of the plume cleaner assembly in a direction at an angle to the apertures. In another example, a plume cleaner assembly with the toilet seat may include at least a fan, an electrostatic collector, and a mist generator. In another example, a plume cleaner assembly is integrated in a tank of the toilet to generate a sanitization fluid that is channeled into the toilet bowl through an overflow tube and/or rim channels.

A light-transmitting member includes a substrate including a resin layer, and a functional film disposed on the substrate. The substrate has a thickness of 1 μm or more and less than 1 mm. An optical thickness of the functional film with respect to light having a wavelength of 464 nm or more and 653 nm or less is less than a half of the wavelength. A contact angle of water with respect to an upper surface of the functional film in the light-transmitting member is less than 90°. The functional film has a porous portion containing a plurality of particles. A first particle and a second particle among the plurality of particles are bound to each other with a binder. Each of the first particle, the second particle, and the binder contains an inorganic material.

Provided is a compact heating cooker system capable of discharging steam and smoke generated when heating and cooking food. A heating cooker system 1A includes a table 10 and a heating cooker 20. The heating cooker 20 includes a casing 21 having an exhaust port 21a, a heat source 22 for heating a cooking utensil X, a top plate 23 having a plurality of suction holes 23a in communication with the exhaust port 21a, an exhaust passage 27 in communication with the exhaust port 21a, a filter 24 arranged inside the exhaust passage 27, an exhaust fan 25 arranged downstream of the filter 24, and a deodorizing device 26 arranged downstream of the exhaust fan 25.

An open-cell foam structure that is impregnated with a disinfectant and used to remove pathogens from air, water, and surfaces, and kill the pathogens

A portable air filtration apparatus capable of rapid and efficient room air turnover and recirculation of filtered and decontaminated air with eradication of both microorganisms and biological agents. The invention relates to a compact device that can be used in ultra-clean air purification using a multi stage electrostatic precipitation and air filtration with disinfection and eradication of both microorganisms and biological agents by the application of ultraviolet light radiation. It can be used in any application where space, lower cost or ultra-fine particulate filtering is needed; such as in clean rooms and surgical suites. The device is extremely efficient for purifying contaminated air from entrained dust and organic substances without using chemicals and physical filters, and it is hygienic and fireproof. The device including its multi stage electrostatic precipitator with the filter, connecting, releasing tubes and the fan is easy to clean and can be portable.

An air purifying breathing system for providing filtered air to a user. The air purifying breathing system comprises a headgear that is not self-contained and is open under a face shield to let air flow out of the headgear. A fan component moves ambient air into the system and across a filtering component. The filtering component comprises a first and second filter, each filter using different filter media. After the air is filtered, it exits the filtering component and into the headgear at the top for distribution to the user. The filtered air flows past the user and out the opening under the face shield. The slight positive pressure from the airflow prevents the inflow of unfiltered air into the headgear. The filtering component may be attached to or integrated into the headgear or may be retained by a vest or harness.

An indoor external air filtering and fragrance diffusing system composed of a cage like apparatus that attaches to an existing air vent and holds in place air filter. The present invention includes a device to hold a filter from the exterior of a conventional air vent, allowing the airflow into a room from the central air system and a customized air filter. The present invention incorporates a variety of air filters that can be adapted to the specific needs of a user. One variation of the filter contains an embodiment that is comprised of absorbent material where a fragrance of choice can be added. Yet another variation of the filter contains an embodiment of absorbent material that already contains fragrance.

An air purification and disinfection system includes an apparatus having a housing, an ultraviolet disinfection chamber, an air mover, and an air distribution unit in communication with the disinfection chamber. Air is passed through the disinfection chamber where it is purified and disinfected before it is delivered to the user of the apparatus through the air distribution unit. The apparatus can be configured as an open or a closed circuit system. The system may be configured to purify air in an airplane, a conference room, a classroom, or as a portable unit for an individual user. As a portable unit the disinfection chamber can be incorporated into a back pack, a vest, a purse, a briefcase, a shoulder bag, a cervical collar, or any other format for being carried by the user.
