An air filtration apparatus includes an airflow powerhead assembly including a fan assembly and a vane assembly, a filter assembly, and a separator chamber housing inside of which the filter assembly is disposed. The separator chamber housing has a chamber inlet at a first axial side and a clean air outlet at a second axial side of the separator chamber housing opposite the first axial side. The filter assembly has a first axial end adjacent the chamber inlet and a second axial end adjacent the clean air outlet. The separator chamber housing includes at least one debris ejection slot extension configured to eject debris from an inner space of the separator chamber housing. The filter assembly includes a debris catch tray disposed at the second axial end, the debris catch tray having a debris ejection slot aligned with the at least one debris ejection slot extension.

Provided is an air cleaner, and more specifically, to an air cleaner in which a filter part using a photocatalyst is formed in a module type to facilitate replacement and cleaning and which includes an insert fan which is disposed inward from a suction port of a casing forming an exterior and including the suction port disposed at one side and a discharge port disposed at the other side, and suctions ambient air, a driving motor provided to be axially detachably coupled to the insert fan in a direction from the discharge port, and a suction unit fixing part in which an accommodation space, into which the insert fan and the driving motor are fixedly inserted in the direction from the suction port toward the discharge port and which is finished by inserting a cover member in the direction from the discharge port.

The present disclosure is related to surfaces having various topographical features and methods of making same. The disclosed features, created on various polycrystalline metallic substrates, may aid in effectively and rapidly reducing or eliminating detrimental effects of microbes. In some embodiments, the surface features may include channels and combinations of angular features such as ledges, ridges, and nodules, which may help adsorption of microbes to the surface, increase the surface chemical activity, and increase the effective surface area to support and/or accelerate the killing or deactivation of microbes. Some embodiments including reducing radii of curvature on channel ledges, intra-grain angular ridges, and angular nodules to accelerate disruption of microbial outer membranes by charge concentration and charge transfer. Also described are methods of producing the disclosed topographical surface features at low cost on various polycrystalline solid metal surfaces, for example cast, forged, rolled, drawn, wrought, deposited or coated.

A portable airborne pathogen control apparatus and system. Aspects of the present disclosure provide for a portable airborne pathogen control apparatus configured to be selectively positioned within an interior room and configured to enable a floor-to-ceiling flow of air within the interior room. The portable airborne pathogen control apparatus may comprise a housing with an air intake disposed at a lower area of a base housing and an air outlet disposed at an upper area of an elongated duct extending from the base housing. A blower fan housed within an interior chamber of the housing may be configured to direct a floor-to-ceiling flow of air through the interior chamber from the air intake to the air outlet. A volume of air directed through the interior chamber of the housing may be disinfected using one or more UV-C emitters and/or cold plasma generator(s) housing in the interior chamber of the housing.

An apparatus and method are provided for an air filter configured to be mounted onto an air inlet of an internal combustion engine. The air filter comprises a first end cap configured to couple with a base which is configured to support a conventional air filter and provide an interface between the conventional air filter and the air inlet. A filter medium which is relatively thicker than the conventional air filter is configured to remove particulate matter and other contaminates from an incoming airstream. A second end cap is configured to couple with a cover which is configured to fasten the conventional air filter and the base onto the air inlet, such that the incoming airstream is directed through the filter medium. The air filter is configured to be installed in place of the conventional air filter without necessitating alteration of the base and cover.
