| 20080216456 | Filter apparatus and method - A filter apparatus removably attachable to at least one of a door frame, a window frame, a screen, a wall, a door, and a window is provided. Such filter apparatus includes a filter member, manufactured from a first predetermined material and having a first predetermined size and a first predetermined shape, for filtering dust, debris, pollutants, insects, dirt, allergens, pollen, rain, and irritants. A frame member is manufactured from a second predetermined material and has a second predetermined size and a second predetermined shape. A mechanism is provided for operably connecting such filter member to such frame member. A fastening mechanism is provided for removably fastening such frame member to at least one of such door frame, such window frame, such screen, such wall, such door, and such window. | 09-11-2008 |
| 20100037574 | Adjustable Filter Racks - Filter racks are disclosed that are adjustable to accommodate filters of various thicknesses. The filter racks may include an insert that can be positioned within the base of the filter rack in two or more positions to adjust the receiving width of the filter rack. A perforated tab of the insert may be unbent to position the insert within the base at a smaller width, and the tab may be bent to position the insert within the base at a larger width. The insert also may include a divider that can be positioned within the base to reduce the width of the filter rack. Further, a rotating guide may be attached to detents within walls of the filter rack compartment. The guide may be biased at various angles to accommodate filters of different widths. | 02-18-2010 |
| 20100071325 | AIR FILTRATION SYSTEM AND METHOD - An air-filtration system and method for removably attaching a filter element to portable air-circulation devices and building HVAC air-intakes. One such system provides a filter portion having a circular outer periphery, an inner periphery, a slit running from the outer periphery to the inner periphery that creates a first and second end of the filter portion, and a plurality of fastening mechanisms. One method includes manufacturing a plurality of air-permeable filter sheets, determining a shape of a portable electric fan that includes a fan cage, a support stand, and a motor casing, measuring a size of an inlet side of the fan cage and a size of the motor casing, cutting the plurality of filter sheets such that a plurality of filter portions are created, and attaching a plurality of fastening mechanisms to each one of the plurality of filter portions. | 03-25-2010 |
| 20100275562 | FLEXIBLE SIZE ADJUSTABLE FILTER ELEMENT WITH END-CAP - An air filter element partially-fabricated on site wherein one or more wire frames are fastened to one another to form a structure substantially conforming to the dimensions of the original equipment manufacturer's filter housing. One or more of the wire frames are flexibly attached to each other end-to-end by flexible attachment means, allowing the assembled filter unit to be inserted into the filter housing one frame at a time, with the frame sections yet to be inserted folded or directed off to one side, thus bypassing space restrictions. Flexible attachment means may comprise spring connectors. Also disclosed is an end-cap affixed to or formed at one or both ends of the filter element. The end-caps may also contain printed material, such as text or pictures, which may include instructions for use, identifying labels or symbols, or the like. | 11-04-2010 |
| 20110314781 | AIR FILTER HAVING DIMENSIONAL EXTENDING TABS - There is provided herein an air filter that includes one or more foldable extension flaps that can be folded and secured against the frame to provided an extend thickness dimension for the frame of the air filter, which allows the same filter to be used in either a smaller or larger filter slot within an HVAC system. | 12-29-2011 |
| 20130219844 | METHOD OF ADHERING A PLEATED FILTRATION MEDIA AND FILTER AND MEDIA FILTER STACK USING SAME - A method of manufacturing a selected spacing folded, pleated media by preparing a pre-pleated sheet of filter media having pleats with peaks and troughs throughout its length applying an at least one adhesive element along the pre-pleated sheet of filter media; advancing and cutting the pre-pleated sheet of material; compressing the cut length of pre-pleated sheet of filter material, resulting in folding of the pleats and adherence of the pleats into a folded, pleated filter media stack that is selectively separable; selectively separating the media stack and selecting a pleat spacing for a selected pleat spacing section application of an at least one spacing support element at the peaks of each pleat and refolding and recompressing into a selected spacing folded, pleated media stack wherein the media stack is adhered and can be selectively removed to extend from a compacted state to a deployed state with the selected pleat spacing. | 08-29-2013 |
| 20130255208 | QUICK ENGAGEMENT METHOD FOR GAS TURBINE INLET FILTER INSTALLATION AND REPLACEMENT - A filter installation arrangement and an associated method of installing a filter assembly to a partition. A filter assembly includes a filter element that extends along a longitudinal axis. The filter element includes an end cap disposed at an end of the filter element. An adjustment device of the installation arrangement axially displaces the end cap of the filter element in a first direction. An insert portion is inserted adjacent the end cap subsequent to the axial displacement of the end cap. The insert portion is configured to limit axial displacement of the end cap in a second direction that is opposite the first direction. | 10-03-2013 |
| 20150101296 | SEGMENTED BENDABLE FILTER - A filter includes a relatively rigid support frame having top and bottom frame members and side frame members. A filter element is disposed within and supported by the frame for filtering a medium passing through the filter element. Two opposing members of the frame are bendable into an arch to allow the filter to be progressively inserted along an arched path into a filter housing. In one embodiment, the filter is a cabin air filter for a vehicle and opposing sides of the frame are provided with V-shaped notches to facilitate bending the filter into an arch for insertion. | 04-16-2015 |
| 20150375156 | METHOD OF ADHERING A PLEATED FILTRATION MEDIA AND FILTER AND MEDIA FILTER STACK USING SAME - A method of manufacturing a selected spacing folded, pleated media by preparing a pre-pleated sheet of filter media having pleats with peaks and troughs throughout its length applying an at least one adhesive element along the pre-pleated sheet of filter media; advancing and cutting the pre-pleated sheet of material; compressing the cut length of pre-pleated sheet of filter material, resulting in folding of the pleats and adherence of the pleats into a folded, pleated filter media stack that is selectively separable; selectively separating the media stack and selecting a pleat spacing for a selected pleat spacing section application of an at least one spacing support element at the peaks of each pleat and refolding and recompressing into a selected spacing folded, pleated media stack wherein the media stack is adhered and can be selectively removed to extend from a compacted state to a deployed state with the selected pleat spacing. | 12-31-2015 |
