A Twist-interlocking Engine Housing and Air Filter System and Method is disclosed. The filter assembly provides unequaled ease of installation and removal, as well as superior sealing between the housing and the filter assembly. For installation, the user needs only to insert the filter into the housing and then give the filter assembly a one-quarter turn or less to lock the filter assembly into the housing. There are features within the filter base that snap-locks the filter in place to resist inadvertent loosening. Finally, the housing and filter are designed so that the outer flange of the filter base is recessed into the side of the housing in order to prevent the intrusion of unwanted grime and/or fluids.

A filter assembly for a fresh air filtration system, the fresh air filtration system made therewith, and a method of filtering fresh air are provided. The filter assembly includes a filter housing and at least one filter element supported within the housing, the housing having at least one inlet for receiving a fluid to be filtered and at least one outlet for discharging filtered fluid, wherein the at least one inlet and at least one outlet are on a common side of the housing.

An adjustable filter track system a filter track having a recess configured to receive a filter, and a frame having a first coupling feature configured to couple to the filter track in a first configuration and a second coupling feature configured to couple to the filter track in a second configuration, where the filter track and the frame are configured to hold the filter in place within the recess, and where the filter track is adjustable between the first configuration and the second configuration to accommodate different thicknesses of the filter.

A filter element for adsorbing harmful gases from a fluid flow includes: a frame and a plurality of filter bodies arranged at a distance next to one another in the frame. A respective filter body has a plurality of openings. A respective filter body is connected to at least one other of the filter bodies via a respective contact element configured for electrical dissipation. The filter bodies are arranged in matrix form, the filter bodies are formed as honeycomb bodies, and/or the filter bodies comprise activated carbon.
