An LED panel for filtering elements for fluids, in particular air, comprising a supporting element having a main lying surface and supporting a plurality of LEDs. The LED the panel also comprises electrical connection means for the connection of the LEDs to an electricity supply source. The supporting element has a grid-shaped configuration having a plurality of through openings configured to allow the passage of a flow of the fluid through the main lying surface of the LED panel.

In one aspect, a modular filter assembly for filtering fluid that flows in a flow direction therethrough is disclosed. The assembly includes a first housing section having a first filter element; a second housing section having a second filter element; and a connector disposed between the first and second housing sections. A housing includes the first housing section, the connector, and the second housing section. The flow direction is through the first and second filter elements in series.

A clothing treatment device includes: a cabinet forming a treatment space in which clothing is accommodated; a door configured to open and close the opened front of the cabinet; a machine compartment having a suction port and a discharge port, the suction port through which air of the treatment space is suctioned, the discharge port through which air is discharged to the treatment space; and a filter module disposed below the treatment space. The filter module includes: a module cover disposed at a lower side of the treatment space; and a filter unit disposed inside the module cover so that the filter unit is allowed to be withdrawn toward a front of the module cover when the door opens the opened front of the cabinet, the filter unit which filters out foreign substances falling down on the module cover.

The present disclosure generally relates to an air filtration system, an air filtration device, and an air filtration module for removing ultra-fine particles (UFPs), pathogens (e.g., viruses, bacteria, etc.), volatile organic compounds (VOCs), oxides or odors. The systems, devices, and filter modules of the disclosure perform at enhanced filter and power efficiencies. An air filtration system is provides that includes a docking base for receiving a removable, portable air filtration device in fluid communication with the docking base. In certain embodiments, the air filtration system further includes the removable, portable air filtration device. The portable air filtration device may optionally include an air filtration module.

A general-purpose air sterilizing system destroys activation of air-borne pathogens, designed with different embodiments. The methods used to build the apparatus allows destroying airborne pathogens like bacteria, mold, mildew, allergens and deactivates viruses such as SARS CoV-2. The apparatus supports air circulation system that contains filter which comprising array of Ultraviolet (UV) Light Emitting Diode (LEDs) of 262-nm wavelength, AKA UVC, are used.

This air handling unit (1) comprises a structural frame (3, 5), and air handling components (15) enclosed within a housing (7), at least one of said components (15) having a rectangular shape arranged orthogonally to an air flow direction (F1, F2), and mounted by its edges (151, 153) on the structural frame. The at least one of the components (15) is mounted by one of its edges (151) on at least one movable rail (17) which is mounted in a sliding manner in a stationary rail (19) integral with the structural frame (3, 5) or the housing (7), the movable rail (17) being extractable with respect to the stationary rail (19) out of the housing (7) so that the component (15) can be extracted from the air handling unit (1).

A coating material mist remover of the present disclosure includes: a first duct that discharges air containing coating material mist from an outflow port directed downward; a second duct having an inflow port opened in a horizontal direction; and an incinerable intermediate filter that is detachably connected between the first duct and the second duct and removes the coating material mist from the air. The coating material mist remover also includes: a first connection mechanism that can connect and separate the first duct and the intermediate filter; and a second connection mechanism that can connect and separate the second duct and the intermediate filter.
