The addition of a medial longitudinal score line (hinge point) along the longitudinal channels of the filter frame allows for thinner media and/or collapsing the frame on itself which will reduce scrap, save space and save tremendously on shipping costs. The additional score line can be a cut score, skip score, crush score or liquid line. The collapsed filter frame expands upon sliding into the channels of the filter frame media holder whereby the filter frame expands and widens to fit the filter assembly.

A separating device for separating a liquid from gas is provided with a separating element that has a housing with housing cover closing off an end face of the housing. A filter element is arranged in the housing. A coupling element is provided to couple the separating element to a connector device. The housing cover has a central first gas passage and a second gas passage arranged radially outwardly of the first gas passage. The housing cover has a housing cover thread correlated with the first gas passage. The housing cover thread is to be screwed to a coupling element thread of the coupling element. A fluid discharge channel is arranged within the coupling element for discharging separated liquid from the separating device. The housing cover thread and the coupling element thread, in a position of use of the separating device, are connected substantially seal-tightly to each other.

A refillable air filter system, including: a reusable and collapsible frame; and a disposable filter that is releasably securable within the collapsible frame, wherein the filter is convertible between a storage/collapsed configuration and a functional/expanded configuration.

A filtration device is provided, configured to be assembled between a tube seat and an air diffuser of a ventilation system, including: a main body, at least one filter and at least one light source. The main body includes an air inlet connected with the tube seat, an air outlet connected with the air diffuser and a shielding portion blocking between the air inlet and the air outlet. The shielding portion defines at least one passage. The at least one filter is disposed on the main body and corresponds to the at least one passage. The at least one filter has a photocatalyst material disposed thereon. An illumination area of the at least one light source corresponds to the at least one passage. A distance between the at least one light source and the at least one filter is smaller than or equal to 100 mm.

A method for controlling display of information on a display device includes storing information corresponding to a broadcast program guide. When a signal is received based on activation of a specific key while the first broadcast program is displayed on a screen, information on the first broadcast program and information on a second program to be broadcast after the first broadcast program is detected. The first broadcast program is then displayed in a first region of the screen simultaneously with the information on the first broadcast program and the information on the second broadcast program in a second region of the screen.

A filter element, a safety element and fluid cleaner assembly. The fluid cleaner assembly generally includes a housing having a cover and a primary fluid cleaner section. The element generally comprises z-filter media, arranged in a straight through configuration, and an axial seal gasket positioned to extend continuously around at outer perimeter of the straight through flow construction. The fluid cleaner assembly can have a precleaner positioned therein. Methods of assembly and use are provided.

A room air purifier including upper and lower portions with the lower portion including a detachable floor panel. The upper portion and the floor panel may respectively include integrated resilient upper and lower gaskets configured so that with an air filter removably installed in the room air purifier and with the floor panel attached to a lower housing piece of the lower portion of the room air purifier, the upper portion of the room air purifier, and the floor panel, apply pressure to the air filter through the upper and lower gaskets.

According to the present disclosure, features, components and techniques useable for providing air cleaner arrangements are provided. Many of the features relate to an axial seal arrangement provided on a filter cartridge. A typical filter cartridge, for use with these features, is a filter cartridge having opposite flow ends. Example media arrangements that fit this characterization are described. Seal arrangements provided with an axial housing sealing engagement surface are shown. A seal arrangement is provided. Also, air cleaner assemblies having advantageous features therein are provided. Further, air cleaner housings are described, with selected, preferred features for engagement with filter cartridges.
