An apparatus may include one or more light components that are configured to emit light to sanitize and disinfect one or more objects included within the apparatus. The apparatus may have an interior cavity at which the light components are located, where the interior cavity is accessible via one or more doors, an opening, a lid, etc. The apparatus may have a conveyor that transports objects from a first end of the apparatus to a second end of the apparatus, where the objects are sanitized during transport. The apparatus may be transitioned from an expanded configuration to an unexpanded/collapsed configuration, and vice versa. The apparatus may be stationary or include wheels or other mechanisms that allow the apparatus to be moved between different locations. Objects that are sanitized by the light components of the apparatus will be free of pathogens (e.g., viruses, bacteria, etc.) that are potentially harmful to humans.

A composition may include microcapsules containing at least one odor-neutralizing agent, and agents may include such a composition. Furthermore, such compositions or agents may reduce malodors and/or be used for treating a surface, for treating room air, or for washing and/or caring for textiles using such compositions or agents.

An air purification device for maintaining a clean smelling bathroom includes a housing, which is mountable to a tank of a toilet, and a plurality of bulbs, which is mountable to an underside of a seat of the toilet. An opening is positioned in the housing to vent the housing. A tube is attached to and extends from the housing to a bowl of the toilet. A battery, a pump, and a filter are attached to and positioned in the housing. The battery is operationally engaged to the pump and the bulbs, positioning the bulbs to selectively illuminate an area proximate to the toilet. The pump draws air from the bowl through the tube into the housing, where the filter absorbs malodorous compounds in the air to purify the air, thus maintaining a clean smell in proximity to the toilet.

Provided is a biomaterial removing device including an air injection part, a first processing part spaced apart from the air injection part, and a second processing part spaced apart from the air injection part with the first processing part therebetween, wherein the first processing part includes a first biomaterial removing part configured to remove biomaterials included in air collected from the air injection part and a first monitoring part, and the second processing part includes a second biomaterial removing part configured to remove the residual biomaterials and a second monitoring part, wherein the first biomaterial removing part includes a dry air purifier, the second biomaterial removing part includes a wet air purifier, and the first biomaterial removing part and the second biomaterial removing part each include an image sensor.

Provided are both a superabsorbent polymer capable of continuously and safely exhibiting an improved bacterial growth inhibitory property and a deodorant property without deterioration in the physical properties of the superabsorbent polymer, such as water retention capacity, absorption under pressure, etc., as well as a preparation method for the superabsorbent polymer.

An apparatus for collecting a gaseous pollutant from air may comprise multiple vertical panel-beds each containing a solid sorbent; a fan to pass the air through the multiple vertical panel-beds and over the solid sorbent; an outlet gate configured to release the solid sorbent from the multiple vertical panel-beds after the fan passes the air over the solid sorbent; a regeneration vessel configured to regenerate the released solid sorbent by recovering the gaseous pollutant from the released solid sorbent; and a conveyor configured to return the regenerated solid sorbent to the multiple vertical panel-beds.

The present invention relates to a sheet filter material, in particular having an aerosol filter function and/or a particle filter function, preferably having a protective function against chemical, biological and/or chemical harmful and toxic substances, and to a method for the production thereof. The sheet filter material is particularly suitable for producing protective equipment, protective objects, sports and leisure clothing and filters and filter materials of all types.

The present invention relates to a food waste dryer comprising: a main body in which a drying space is formed so that a portion thereof is open to the outside; a front door for closing the open portion of the main body; a drying basket which is disposed in the drying space of the main body and in which food is accommodated; an air circulation unit which includes a heater capable of heating the air of the drying space, and which suctions the air inside the drying space, and then blows, at the food waste, the air heated by the heater so as dry the food waste; a circulation pipe capable of discharging, to the outside through an exhaust pipe, the air that includes steam vaporized during a food waste drying process, and recirculating, to the drying space through a blowing pipe, the air heated by the heater; and a deodorizing device mounted on the outside of the main body so as to adsorb odor particles from the air discharged to the outside through the circulation pipe, thereby enabling the air to be deodorized, wherein the deodorizing device includes a deodorant comprising activated carbon and zeolite. According to the present invention, a fixed amount of steam, which is generated by vaporization and evaporation during the food waste drying process, is maintained, and the adsorption and deodorization performance of the odor particles can be improved.

Systems and methods for detecting, capturing and/or disinfecting viruses. A water trap system includes a water-filled container through which air is introduced into a water-filled container. Charged viruses, bacteria and other contaminants become trapped in the water-filled container as they are entrapped by oppositely charged atoms (e.g., oxygen). Another device incorporates an electric field created by a pair of electrodes with an outer surface heated to a threshold temperature significant enough to disinfect viruses that come into contact therewith. Another device is a portable inhaler for detecting the polarity of airborne viruses and counting the positive and negative electrical charges of airborne viruses with tolerances of a few charged particles per cubic centimeter by sampling several hundred cubic centimeters of air per second. Consequently, the portable inhaler is capable of quickly and efficiently detecting whether a person has contracted a virus (e.g., COVID-19 virus).

The present disclosure provides a filtration media for filtering one or more airborne particles. The filtration media may comprise a membrane comprising one or more polymeric layers to filter the airborne particles. The filtration media may have high filtration efficiency and high breathability. Additionally, the present disclosure provides devices (e.g., face masks) comprising the filtration media which may be used to filter airborne particles (e.g., bacteria, viruses) and to protect the wearer (e.g., from infection).
