BACKGROUND OF THE INVENTION
1. Field of the Invention
In general, the present invention relates to an air filter or screen. More particularly, the present invention relates to a new and improved filter and or screen utilizing natural or man made organza material fitted to cover apertures such as but not limited to windows.
2. Description of the Prior Art
For purposes of decreasing energy use, it is found that it is more practical, economical, and environmentally friendly to use windows to circulate air when allowable than to constantly run heating and air conditioning systems. In the world today, it is increasingly more favorable to use non-energy required systems such as windows to allow air flow into such buildings as homes and businesses as opposed to energy consuming devices that accomplish the same goal as using an open window.
One of the obvious drawbacks to window use today is the lack of desirable air filtering associated with an open window. This can be a significant shortcoming depending on the air quality in the community, health needs of individuals, location of windows, and so forth. Obviously, depending on the air quality, it would never be desirable to use an open window for air circulation if the air could not be filtered in some way.
In modern construction today, it is common for windows to be fitted with mesh wire or mesh plastic screens to allow air to pass through the open window while preventing such things as insects from also passing through. The mesh or screens are generally configured from intersecting or crossed lines at perpendicular angles with a desired density that allow for viewing through the window as well as act as a screen. These typical mesh constructions are configured for preventing insects from passing, but not configured for preventing smaller or finer items such as pollen, dust and so forth. It is understood that the denser the mesh or screen, the smaller the items are prevented from passing through, but also the less ability to see through the window.
It is also known to provide air filters for such things as air conditioners and heating systems, but these are not typically used in association with windows where it is desirable to have viewing or light pass through. By example, these filters are provided specifically to clean air, but are essentially worthless if the air conditioner or heating system is not on—such as when windows are opened in place of running air conditioning or heating systems.
Due to the varied needs and uses, the prior art devices have failed to provide an adequate solution to air filtering for window wherein visibility is still sufficiently allowed. Today, the current consuming industry is looking for an easily installed, durable, and cost effective air filter for window. Thus, there is a need for a new and improved air filter for windows and the current invention provides a superior solution where the prior art fails.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of screens and air filters now present in the prior art, the present invention provides a convenient, easily installed, and durable construction. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved air filter and method of constructing the same which has all the advantages of the prior art and none of the disadvantages.
It is contemplated that the invention may take an existing frame or structure, such as but not limited to a screen for a window, and provide an air filter made of either natural or man made organza material. It is contemplated that the air filter organza material may be attached in numerous configurations and used in numerous applications wherein it is desirable to provide an air filter that allows for visibility.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

BRIEF DESCRIPTION OF THE PICTORIAL ILLUSTRATIONS GRAPHS, DRAWINGS, AND APPENDICES
The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed pictorial illustrations, graphs, drawings, exhibits and appendices wherein:
FIG. 1 is a partially exploded illustration of a preferred embodiment of the invention essentially depicting a screen and frame assembly, a filter such as but not limited to organza, and an assembly therewith.



DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, wherein like reference numerals designate corresponding structure throughout the views, and referring in particular to FIG. 1, reference numeral 10 generally refers to a new and improved air filter made from organza material, method of construction, and combinations thereof (hereinafter referred to collectively as invention 10) in accordance with the present invention.
Invention 10 may utilize a filtration material 20 such as but not limited to organza. Typically, organza is a thin, plain weave, sheer fabric traditionally made from silk, the continuous filament of silkworms. Currently, the most luxurious organzas are still woven in silk although many organzas are now man made and woven with synthetic filament fibers such as polyester or nylon. Organza is typically sheer and can be nearly completely see through, partially see through, and or non-see through. It is contemplated that the current invention may use various density and ability to see through the material as desired. It is understood that organza may be of tight weave to allow air to flow through, but stop or catch other non desirable air particulates such as dust, pollen, and so forth.
In a preferred construction, invention 10 may utilize a frame 30 wherein filtration material 20 is attached and or removably attached. Frame 30 may already be utilized to hold a screen or mesh 40 known in the art. It is contemplated that numerous configurations or frames may be utilized to hold filtration material 20 where desired as well as attaching filtration material 20 directly to the aperture where it is desired to filter air. The illustrations depicting use with the frame 30 should not be considered to limit the invention as such. It is further understood that invention 10 may not utilize screen 40 and that filtration material may just be attached to frame 30.
Furthermore, it is understood that invention 10 may be utilized on windows and openings (not depicted) for homes, buildings, recreational vehicles, camping tents, and so forth. Invention 10 may be further utilized in heating and air conditioning systems that may not have visibility utilizations commonly associated with windows.
It is also understood that filtration material 20 may allow air flow 50 through filtration material 20 such that filtered air 60 is achieved. It is contemplated that air flow in general may flow through either direction and the illustrations should not be considered to limit the application as such.
It is contemplated that filtration material 20 may be utilized wherein an individual may apply filtration material 20 to existing frames 30 utilized in existing structures. It is further understood that invention 10 may not be a retrofit of the existing frame 30 structure, but rather an original construction. It is also contemplated that filtration material 20 may be stapled, tacked, glued, heated, combinations thereof or otherwise fixed to areas where filtration is desired and or shading and or color accents.
In a preferred embodiment, frame 30 may have an outer edge 80 for contacting a window frame, an inner edge 90 generally defining the interior of frame 30, and a binder 70. Binder 70 may include a groove (not shown) in frame 30 wherein a piece of generally elastic material or filler is used to trap or secure screen 40 and filtration material 20 to frame 30. In a preferred construction, screen 40 and filtration material 20 may be stretched across frame 30 generally covering the interior of frame 30 and groove wherein binder 70 is stretched or held in place.
Furthermore, it is also contemplated that a preferred embodiment of the invention may utilize various colors as desired. By example, matching colors of material 20 could be utilized for aesthetic reasons to match home décor, contrast, or further accent.
Changes may be made in the combinations, operations, and arrangements of the various parts and elements described herein without departing from the spirit and scope of the invention.
