A gas detection and purification device can be placed in an in-car space and includes a housing, a purification module, a gas-guiding unit, and a gas detection module. The housing has a gas inlet and a gas outlet. A gas channel is between the gas inlet and the gas outlet. The purification module is disposed in the gas channel to filter the gas guided into the gas channel. The gas-guiding unit is disposed in the gas channel and at one side of the purification module. The gas-guiding unit guides the gas into the device from the gas inlet, guides the gas to pass through the purification module for performing filtering and purifying, and discharges the gas out from the gas outlet. The gas detection module is disposed in the gas channel to detect the gas guided into the housing to obtain gas detection data.

Carbon fiber composite additives, media incorporating the carbon fiber composites, and related methods are provided herein. In some aspects, a composition includes at least one medium; and a carbon fiber composite incorporated with the at least one medium, the carbon fiber composite including one or more carbon fibers with an epoxy resin matrix applied thereto to produce a composition having improved characteristics and filtration performance.

A collapsible smoke containment apparatus for safe and accessible smoking includes a floor having a ramp. A frame includes a frame front side, a frame back side, a frame left side, and a frame right side each coupled to a frame base. The frame front side has a door aperture aligned with a pair of ramp outer edges of the ramp. A door is coupled to the frame. A film cover is coupled to the frame and has a cover front side, a cover back side, a cover left side, a cover right side, and a cover top side. The film cover has a plurality of cover apertures extending therethrough. Each of a plurality of filter units comprises a filter housing coupled to the film cover around one of the cover apertures. A recirculating fan and a ventilation fan are coupled within the filter housing.

A composite absorbent filter media having adsorption and/or absorption properties for the filtration of ester oils from a liquid includes a graphene and/or graphite composite mixed into a final emulsion, which is subsequently heat treated or cured, cooled, compressed, and dried. The resultant adsorption/absorption media is then disposed within a plug structure having an ingress and egress for liquids mixed with ester oils to pass through. Alternatively, the resultant adsorption/absorption media is disposed into a fabric and formed as a wall used to enclose oil-filled equipment. The media adsorbs/absorbs the ester oils from the liquid, while allowing the liquid to disperse and pass through.

The present disclosure provides a preparation method of carbon black synthetic filter materials and an application thereof, which are prepared by impregnating nonwoven fabric filter fibers in a mixed solution consisting of carbon black, animal glue, glycerin, urea, cupric complex of amino acid, Turkey red oil, methylsilicone oil and deionized water, the nonwoven fabric filter fibers are coated with carbon black; wherein, the mixed solution is composed of the following weight parts of raw materials: 2˜4 parts of carbon black, 1˜3 parts of animal glue, 1˜3 parts of glycerin, 0.2˜0.4 parts of urea, 0.03˜0.06 parts of cupric complex of amino acid, 0.05˜0.15 parts of Turkey red oil, 0.05˜0.15 parts of methylsilicone oil, and 45˜55 parts of water. The present disclosure can improve the elimination of contaminants effectively and utilizing the installation space for the current filters efficiently, with strong practical significance and promotion value.

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.

Implementations of the disclosed subject matter provide face mask that may include a transparent portion configured to cover a nose and mouth when disposed on a wearer, where the transparent portion includes a left front opening and a right front opening. A first strap and a second strap may be affixed to the transparent portion. A first filter may be configured to be removably disposed in the left front opening of the transparent portion to filter air, and a second filter configured to be removably disposed in the right front opening of transparent portion to filter the air. A first module may be configured to be removably affixed to the first filter and a second module configured to be affixed to the second filter. The modules may include a controller, a fan, a speaker, a microphone, a display, a memory, a communications interface, and/or a plurality of light emitting devices.

A toilet odor elimination device that resides below a water tank lid of a water tank includes a housing with an intake chamber, a filter chamber in operational relationship to a micro fan chamber, a tubular exhaust tube and an at least one battery storage chamber. The toilet odor elimination device is activated by an on/off switch that resides in an electrical relationship to a power source located in the at least one battery storage chamber.

A dispensing container facilitates convenient chilling and dispensing of water, with a filtration arrangement provided to promote water purity. The system includes a generally cylindrical filter assembly positionable within a liquid container, so that the filter assembly is generally submerged in the water within the container. The filter assembly can be operably connected to a liquid spigot, so that when the spigot is opened, liquid within the container flows through the filter assembly and out of the container, through the opened liquid spigot. Convenient use by consumers is promoted by the provision of a filter protector, comprising a selectively removable, shrink-wrap sleeve surrounding the filter assembly. The shrink-wrap sleeve is positioned on the filter assembly to protect the assembly prior to removal of the shrink-wrap sleeve. A removable tape element is provided to temporarily connect the filter assembly to the spigot prior to use.
