Provided is a filtration device that can increase a filtration treatment amount by suppressing clogging of a filtration filter. A filtration device according to the present invention includes: a filtration filter that includes a filter that filters a filtration target contained in a fluid, and a frame that holds the filter; a support structure that holds the frame such that the filter is bent; and a fluid supplying unit that supplies the fluid with the filter being in a bent state.

Various high performance, high efficiency filter media are provided that are cost effective and easy to manufacture. In particular, various filter media are provided having at least one layer with a waved configuration that results in an increased surface area, thereby enhancing various properties of the filter media. The filter media can be used to form a variety of filter elements for use in various applications.

A ventilation assembly and an air conditioning apparatus are provided. The ventilation assembly includes: a volute, a surface of the volute being provided with a mounting port; a filter assembly arranged in the mounting port or in a portion of the volute adjacent to the mounting port; and a sealing member arranged with the mounting port or with the portion of the volute adjacent to the mounting port, and configured to seal a gap between the filter assembly and the mounting port.

Economical, easy to install and use, and disposable, air filter for an HVAC system. The filter is quasi-universal with respect to the size of the air intake vent over which it can be deployed, and it requires less frequent replacement of filter material than is common with typical throwaway (box-type) air filters. When replacement of filter material is needed, the replacement can be done with less or no direct handling of or exposure to the dirty filter material. In use, the filter maintains relatively consistent cleanliness of the filter material by automatic, periodic scrolling of the filter material to replenish the filtering surface.
