A tobacco smoke containment and filter device with built-in ignition for treating secondary and side stream tobacco smoke that includes a main body portion having an outer chamber and an inner chamber, a mouthpiece, and a housing unit that includes a cigarette ignition system, a fan and a filter. The main body portion includes an outer chamber connected to the housing unit. The mouthpiece has an opening therewith sized to accommodate a cigarette. The outer chamber includes a smoke exhaust member branching off from the exterior of the outer chamber. An inner chamber is positioned within the outer chamber and has a closed far end containing at least one air hole and a near end joined to the outer chamber forming an opening for the mouthpiece. The mouthpiece has a smoke control system that controls the inhalation and exhalation of smoke by the user. (printed circuit board).

An apparatus and method for removal of contaminants from vented vapors having a pressure indicator/stop assembly.

A connector for use in a respiratory system. The connector can connect a first respiratory system component such as a filter to a second respiratory system component. The connector has a body defining a bore for receipt of a complementary connector component. The bore has a terminal end that provides an entry into the bore for the complementary connector component. The connector comprises at least one internal retaining feature, at least one internal alignment feature, and/or at least one external alignment feature.

A hydrophobic filter for filtering an airflow or another gaseous flow in a medical application comprises a housing encompassing a filter chamber, an inlet port arranged on the housing and forming an inlet opening, an outlet port arranged on the housing and forming an outlet opening, and a hydrophobic structure extending along a plane of extension and separating the filter chamber into an inlet chamber and an outlet chamber. The inlet opening opens into the inlet chamber and the outlet opening opens into the outlet chamber. Herein, the outlet opening opens into the outlet chamber at a first location when viewed along the plane of extension and the inlet opening opens into the inlet chamber at a second location different from the first location when viewed along the plane of extension.

The system to be installed on a vehicle to purify air using kinetic energy generated by movement of the vehicle is presented. The system comprises at least one kinetic air purifier structure which is an air conduit having a first particle collection chamber and a second particle separation chamber. Each chamber comprises at least one convex element that provides obstacle to the air flow to separate large particles from the air flow, at least one trapping element, such as cotton fabric, to trap smaller dirt particles, and at least one chamber orifice that allows access to the chambers for cleaning purpose. The system further comprises a micro-porous trapping element to trap micro particles. Due to separated and trapped particles at various chambers, the air is purified. The air purification is achieved by capturing the dirt particles instead of diminishing those.

A filter unit for use With a filtrating fluid flow system is configured to receive a flow of a fluid containing particulate matter. The filter unit comprises a filter structure formed of a filter material configured to at least partially filter the particulate matter from the flow of fluid. The filter unit further comprises an entry plate located proximate the filter structure entrance. The filter structure and the entry plate together define a fluid cavity within the filter unit, the entry plate having at least one orifice defined therein through which the flow of fluid can pass into the fluid cavity. The orifice is configured to form a choke, creating a Venturi effect for temporarily increasing the velocity of the flow of fluid through the entry plate and within the fluid cavity, and onto the filter material.

Air filter system includes a main housing, in which a primary filter cartridge can operably be installed, the housing includes a clean air outlet and a service opening through which the primary filter cartridge can be installed, a pre-separator assembly mounted onto and closing off the service opening, the pre-separator assembly having an inlet flow face receiving air to be cleaned from the outside, an outlet flow face through which pre-cleaned air exits, the outlet flow face positioned over the service opening of the main housing, such that pre-cleaned air is provided to the main housing, a dust discharge port, through which particles pre-separated by the pre-separator can be discharged, wherein the main housing comprises a connection port operable to sealingly connect to the dust discharge port on one side and sealingly connect a scavenge line on the other side, the connection port operable to connect the dust discharge port and a scavenge line.

An air cleaner assembly and components therefor are described. The components include features of an air cleaner housing; advantageous main filter cartridges; and, advantageous safety filter cartridge features. Features of the main filter cartridge are provided to engage an access cover of the assembly, and a cartridge support within the housing, in a preferred manner. Methods of assembly and use are also described.

The present invention is directed to a gladhand connector having multiple ports and an integrated filter. The connector has a base that includes an air hose connector clamp on a first surface, and a first access port extending from the first surface toward a second surface, and a second access port on a bottom surface. The access ports are in fluid communication with an intermediate conduit configured to direct air received from an air hose through the housing. The connector also comprises a receptacle adjacent the first access port and in fluid communication with one of the access ports. The receptacle is configured to receive a pressure sensitive, removable and replaceable filter assembly that is configured to filter debris. The filter assembly is displaceable by air pressure of received air. The connector further comprises a mounting bracket configured to be attached to a vehicle.

A refrigerator including a cabinet, a liner defining a compartment within the cabinet, a fan to move cooled air, and an air tower positioned adjacent the liner and provided in fluid communication with the compartment via a plurality of primary exhaust openings. The refrigerator further includes an air filter bracket separate from and located adjacent to the air tower and provided in fluid communication with both the air tower and the compartment. The ir filter bracket includes a duct positioned adjacent the flow path of the air tower to be in fluid communication with a secondary exhaust opening of the air tower.
