AI Technical Summary

Problems solved by technology

Because a relatively tight fit is required to maximize filter efficiency, the filter can be difficult to remove once installed
[0006] Additionally, inert media has the disadvantage of not being able to remove airborne pollutants other than particulate matter larger than mesh filter media

Embodiment Construction

[0027] The present invention shows two components, including (1) the active material in one or more media grids, and (2) a removal tool. Components (1) and (2) can be used together or separately.

[0028] Go to part (1) first, figure 1 A typical removable disposable filter 20 is shown. The inert medium 22 is held in the usual manner in a mesh 24 (also referred to as a "filter substrate") secured to a frame 28 . The present disclosure contemplates that mesh 24 can alternatively be a mesh filter element. In a preferred embodiment, active media 26, such as activated carbon and / or zeolites, is dispersed in the media grid. In some implementations, active medium 26 can include multiple active ingredients. For example, active medium 26 can include two active ingredients, such as activated carbon and zeolite. The present disclosure contemplates that active medium 26 can contain more than two active ingredients. It should also be understood that activated carbon and zeolite are ...

Abstract

A device is adapted for facilitating the removal and replacement of standardized HVAC vent system filters for primarily return air flow where contaminants are caught in the filter. The device includes a substantially rigid frame defining the perimeter of the filter, a designated location of the frame for attaching a removal device and an elongated tool for engaging the removal device for facilitating removal of the filter. The filter system may include a filter substrate mounted in the frame and containing one or more active ingredients to further improve the filter function.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Patent Application No. 16 / 113,396, filed August 27, 2018, entitled "Replaceable HVAC Filters," the disclosure of which is hereby expressly incorporated by reference in its entirety. Background technique [0003] technical field . The subject matter of the present invention relates to removable and replaceable filter systems for heating, ventilation, and air conditioning ("HVAC") units, and more particularly to a tool that may be integral or separate and that is portable, not only For new filter systems and also as a retrofit for currently used filters. [0004] Discussion of prior art . Many HVAC systems have replaceable filters carried in specific openings located on the return air flow side of the system plenum. Known filters of this type are commonly available to consumers at home stores such as Lowes or Home Depot. Generally, it is recommended to replace these filter...
