An integrated autonomous air purification device for taking in polluted air, carrying it through the inside of the purification device where it passes through a set of filtering elements (1) that trap the dust particles contained in the air; ultraviolet-light lamps (2) that transform NO.sub.X and CO gases in the air into harmless compounds; an activated carbon filter (4) that traps and eliminates the volatile organic compounds and inorganic acidic gases; second filtering elements (5) that carry out a second filtering; and an extraction hood (6) configured to direct the air coming out of the second filtering elements (5) to at least one nozzle (7) that expels the air to the outside of the purification device.

A scent device comprises a container defining a volume and configured to hold a fill material, which may include one or more chemical compounds, natural formulations, or both configured to absorb odor and/or moisture, and/or emit a scent. The scent device includes a vented cap reversibly coupled to the container via a connection mechanism, and a breathable insert sandwiched between the container and the cap. The breathable insert may comprise a non-woven fabric supported along its perimeter by a structural mount. Methods of manufacturing the scent device involve cutting a mount from a support material, attaching a breathable material to the mount to form a breathable insert, depositing a scent-controlling material within a container, and sandwiching the breathable insert between the container and a cap upon coupling the cap with the container.

An open-cell foam structure that is used to detect and remove substances from water or air.

A storage apparatus according to an embodiment may include a body having a storage space of storage products and an air purifying module coupled to the body. The air purifying module may include a light emitting diode part disposed along a passage of air to provide ultraviolet light, and a filter part disposed adjacent to the light emitting diode part.

An infectious agent attenuating or inactivating personal protective equipment device, such as a surgical mask, multilayer mask or respirator having at least one porous filtering layer impregnated with an infectious agent attenuating or inactivating solution that tries to leave behind an infectious agent attenuating or inactivating attenuator composed of an organic acid that preferably is a citric acid, a humectant that preferably is a gelling humectant that preferably is sorbitol which produces or forms a self activating or self replenishing infectious agent attenuator gel and infectious agent attenuating and inactivating air treatment media having a pH of no greater than 5, preferably no greater than 4 and more preferably no greater than 3.5 which is kept moist and activated at or below the desired pH by moisture in the breath of a person wearing the mask. The solution can include a surfactant, such as preferably a rhamnolipid biosurfactant that reduces surface tension both during impregnation of the solution thereby more uniformly impregnating the solution into the at least one porous filtering layer producing an air treatment media having infectious agent attenuating gel more uniformly distributed throughout. The surfactant remains in the gel and reduces surface tension of aerosols and droplets containing viruses and bacteria entrained in the air flowing through the air treatment media contacting the infectious agent attenuating gel more rapidly and efficiently attenuating or inactivating the viruses and bacteria preferably also destroying them by lysing them.

An apparatus for irradiating air flow in a vehicle includes a filter unit configured to couple to a recirculating-air conduit connected to a manifold of an air circulation system, the filter unit having an inlet end, and a filter disposed in the inlet end of the filter unit, including an outer High Efficiency Particulate Air (HEPA) media. The apparatus further includes a plurality of ultraviolet light transmissive strands that each have distal ends disposed in a spaced apart manner in an interface region between the outer HEPA media filter and an inner activated carbon filter or HEPA filter, and proximal ends connectable to an ultraviolet light emitting source such that ultraviolet light is transmitted by the transmissive strands into the interface region. The transmissive strands are configured to receive emitted ultraviolet light that is substantially between 222 nm and 265 nm for irradiating air passing through the filter.

An apparatus for irradiating air flow in a vehicle includes a filter unit configured to couple to a recirculating-air conduit connected to a manifold of an air circulation system, the filter unit having an inlet end, and a filter disposed in the inlet end of the filter unit, including an outer wall of filter media having a shape that defines an interior volume of the filter. The apparatus further includes an ultraviolet light disposed on an end plate, configured to be mounted with the ultraviolet light positioned in the interior volume of the filter and the end plate against an open end of the filter. The ultraviolet light is configured to emit ultraviolet radiation substantially at between 222 nm and 265 nm for irradiating air flow through the filter into the air circulation system.

A system for providing a centralized aerosol source extraction and filtration system is disclosed. The system includes an aerosol capture component coupled to a set of aerosol capture ductwork being located at or near a patient's mouth while treatment is being provided and is coupled to a set of aerosol capture ductwork, a filter and fan component coupled to the set of aerosol capture ductwork for generating the necessary pressure differential to draw the air about the patient's mouth into the aerosol capture component along with any airborne particulates, contaminants, and pathogens, and a recycled clean air component for returning recycled clean air back to patient areas and workspaces through a set of recycled clean air ductwork arranged to create positive and directional airflow throughout the office space. The filter and fan component has one or more filter layer types to remove particulates, contaminants, and pathogens from an air flow received from the set of aerosol capture ductwork.

The present invention relates to a water-soluble effervescent solid perfume comprising a high content of fragrance which does not include organic solvents such as surfactants, preservatives, and alcohols. In addition, additional components may be carried for cleaning and sterilizing effects, and the effects of fragrance, cleaning, sterilization, and the like may be increased by impartation of an effervescent property. Furthermore, there is no generation of residual by-products after effervescent, and may be processed into a solid formulation, thereby improving stability and improving portability and convenience of use.

A deodorant composition may be suitable for use with an aldehyde gas or a ketone gas, and may include an aminoguanidine salt and a metal chelating agent. The aminoguanidine salt is preferably at least one of an aminoguanidine hydrochloride and an aminoguanidine sulfate. The chelating agent is preferably at least one of an inorganic phosphoric acid and salt thereof, and a carboxylic acid and salt thereof.
