Embodiment Construction

[0062]In the following description of preferred embodiments, reference is made to the accompanying drawings which form a part hereof, and in which it is shown by way of illustration of specific embodiments in which the invention can be practiced. It is to be understood that other embodiments can be used and structural changes can be made without departing from the scope of the embodiments of this invention.

[0063]Although embodiments of the invention may be described and illustrated herein in terms of a single example air filter, it should be understood that embodiments of this invention are not limited to the exact shape illustrated, but rather, include a wide variety of generally curved shapes, generally sinusoidal shapes, or generally curving shapes that provides a relatively large surface area in a given volume of the filter.

[0064]An air filter including a base and a first and second frame element is disclosed. Each frame element is coupled to the base. The frame elements have an...

Abstract

An air filter including a base and a first and second frame element is disclosed. Each frame element is coupled to the base. The frame elements have an oscillating shape having a first portion relatively close to the base and a second portion relatively farther from the base. A filter element generally follows the oscillating shape of the frame elements. An air filter system is also disclosed. The air filter system can include the air filter and an air filter container. The air filter container contains the air filter and directs air through the air filter in a predetermined direction. An air filter is disclosed including a support structure and an oscillating shaped filter element attached to the support structure. The oscillating shape increases the air filter surface area for a given volume.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional of U.S. patent application Ser. No. 15 / 619,320 filed on Jun. 9, 2017 and continuation-in-part of U.S. Patent Application, entitled “Air Filter,” filed on Apr. 30, 2012, and having application Ser. No. 13 / 460,518, issued as U.S. Pat. No. 9,682,341, the entirety of the application is being incorporated herein by reference.FIELD OF THE INVENTION[0002]The field of the invention is generally related to filter devices. More specifically, the field of the invention is related to air filters.BACKGROUND[0003]An air filter designed to remove particulate is generally a device composed of fibrous materials. These fibrous materials may remove solid particulates such as dust, pollen, mold, and bacteria from the air. Air filters are used in applications where air quality is important, notably in building ventilation systems and in engines.[0004]Air filters may be used in automobiles, trucks, tractors, locomotives and oth...
