Disclosed is a disposable filter capsule apparatus that incorporates integral quick connect components and check valves to facilitate assembly to, and dis-assembly from, larger assemblies and apparatus. The quick connect elements and valves are configured to eliminate the need for auxiliary sealing elements, e.g., o-rings and valve springs so as to prevent unwanted reactions with fluids and/or gases flowing through the capsules, and to further prevent the disposal of expensive re-usable elements in the disposable capsules.

The present invention provides a photocatalytic filter module and an air purifier including a base frame in which at least one side is open, a plurality of support frames arranged to traverse the base frame, a plurality of light emitting units arranged on the support frame, and filter units installed in the base frame and disposed to be spaced apart from the light emitting units.

Disclosed herein is a system for purifying air; for the capture of solid residues (soot), and the transformation of CO.sub.x and NO.sub.x (and even methane) present in contaminated air generated by industrial combustion.

The purifying air system comprises an air entrance (c); a first module (A), made up of mechanical filters; a second module (B), downwards from the first module (A), and it corresponds to a series of small reactors with molecular converters (nucleophile chemical agents) to capture and transform carbon oxides (CO.sub.x) and nitrogen oxides (NO.sub.x); and an exit for decontaminated air (D).

In order to provide a filter system for separating off contaminants from a stream of untreated gas that contains contaminants that is of simple construction and is operable efficiently, it is proposed that the filter system should include the following: a base construction through which the stream of untreated gas is guidable and which includes at least one filter module receptacle for receiving at least one filter module, and at least one filter module which is selectively arrangeable on and/or in the at least one filter module receptacle and/or removable therefrom, wherein the at least one filter module includes a plurality of filter element receptacles for receiving a plurality of mutually independent filter elements.

A system and related method for air filtration and therapeutic relief are provided. The system includes a base layer, a substrate and a plant medium layer, which can be live, preserved or dormant moss. In some instances, the system also includes one or more netting layers. The system can also include a watering system, or air circulation system, or both.

An air cleaner according to an embodiment of the present disclosure includes: a main body including a main fan configured to generate air flow, a discharge part through which air passing through the main fan is discharged, a wireless power transmitter disposed on one side, and a power supply connected to the wireless power transmitter; and a flow switching device movably provided on the one side of the main body, wherein the flow switching device includes: a first guide tool configured to guide a first direction rotation of the flow switching device; a second guide tool configured to guide a second direction rotation of the flow switching device; and a wireless power receiver configured to supply power to the first guide tool and the second guide tool.

A filter unit includes: a frame having an outer shape surrounding an opening through which air flows and having a collection surface and an opposite surface opposite to the collection surface; and a filter member that is disposed in the opening and filters foreign substances included in the flowing air. A folding groove is formed on the opposite surface of the frame. The folding groove is formed at at least two points of the frame so that when an external force is applied from the opposite surface of the frame toward the collection surface, one of a part and another part of the frame divided based on the folding groove relatively rotates toward the other one, and the frame is folded in such a way that a portion of the collection surface approaches another portion of the collection surface.

In order to provide a filter system for separating off contaminants from a stream of untreated gas that contains contaminants that is of simple construction and is operable efficiently, it is proposed that the filter system should include the following: a base construction through which the stream of untreated gas is guidable and which includes at least one filter module receptacle for receiving at least one filter module, and at least one filter module which is selectively arrangeable on and/or in the at least one filter module receptacle and/or removable therefrom, wherein the at least one filter module includes a plurality of filter element receptacles for receiving a plurality of mutually independent filter elements.

A composite filter includes a filter unit including a filter member having filtering parts, at least one filter module arranged in parallel with at least one of the filtering parts, and a bracket supporting the filtering parts disposed adjacent to each other and the filter module so that the filtering parts disposed adjacent to each other are rotatable. The bracket includes a folded portion that is selectively folded according to the relative rotation of the filtering parts, and attachment portions connected to the folded portion with the folded portion interposed therebetween, and attached to the side surfaces of the filtering parts disposed adjacent to each other. The folded portion and the attachment portions are provided integrally and are formed of a flexible material, and the attachment portion extend to the side surface of the filter module adjacent thereto to seal a gap between the filtering part and the filter module.

The invention relates to a ceramic modular filter element comprising a first elongate hollow body, a second elongate body and a sleeve for coupling the first elongate body to the second elongate body, wherein the first elongate hollow body comprises a frustoconical section, the second elongate hollow body is configured to receive the frustoconical section of the first elongate hollow body and the sleeve comprises projections for engaging with a surface of the first elongate hollow body and/or the second elongate hollow body.
