Benefits of technology
This invention is a filter system that can remove grease from the air, making it easier for baffle filters to stay clean and protect firefighters from damage. Additionally, the invention includes an attachable bracket that can support grease filters in commercial kitchens without requiring any permanent changes to the exhaust hood. The bracket is easy to install and clean, and can be easily removed for maintenance or replacement.
Problems solved by technology
In applications using existing wool or fiber-based filters, problems may be encountered due to excessive heat or flame.
Unless stainless steel heat shields are placed in front of the wool or fiber-based filters, there is the possibility that concentrations of heat (e.g., from exhaust of the cooking equipment) may degrade the wool and / or other fibers and cause a hole to form in the filter.
Similarly, flames may make holes in the filter if they come in direct contact with the filter which occurs above griddles and grills with a grease flare-up.
This is a major drawback since a hole in the filter renders it ineffective and requires that the filter be replaced.
Existing wool or fiber-based filters often require a separate support frame and an additional frame cover made of metal, which is both costly, labor intensive, heavy for the operator to use, and susceptible to damage, often requiring costly replacement.
This assembly, often along with an optional heat shield, causes the current wool-based system to be not only expensive to make but it can be difficult for the user to operate.
In addition, wool or fiber-based filters may include a non-metallic support frame that is embedded inside of a filter mat, but this does not allow for reuse of the support frame, making the replacement filters very expensive for operations.

Abstract
A filter assembly includes: a filter pad including fibers selected from wool fibers, wood-based viscose fibers, and cellulose-based synthetic fibers, the fibers configured to absorb grease particulates; a baffle-type filter; and a support bracket configured to support the filter pad. The support bracket includes: a clip portion that is substantially u-shaped; an attachment portion including a mounting hole formed in a surface thereof; and a support portion arranged between the clip portion and the attachment portion, the support portion configured to support the disposable filter thereon. The filter assembly includes a hanging bracket configured to support the filter pad therein, the hanging bracket including a front wall, an attachment wall including a mounting hole formed in a surface thereof, and a top wall arranged between the front wall and attachment wall. The support bracket and the hanging bracket are configured to mount the filter assembly to an exhaust hood.
Description
BACKGROUND OF THE INVENTIONField of the Invention[0001]The invention relates generally to filters, mounts or brackets for mounting filters, and methods of mounting filters.SUMMARY OF THE INVENTION[0002]Filters may be employed in canopies or hoods overlying relatively large grills, broilers, ranges, stoves and like equipment in kitchens, for example, in restaurants and other facilities where food is prepared. Such filters may be typically provided with a rectangular frame to which rows of baffles are secured in staggered relation to form a grease and / or flame retarding filter for a kitchen exhaust / ventilation system. Nevertheless, there remains a need for a disposable grease filter pad, which is removable and replaceable, and which may be used in conjunction with a separate UL1046 listed grease filter, or the like. The disposable grease filter pad may be in place for extracting grease from grease-laden exhaust air and removed for permitting direct cleaning of all filter surfaces.[000...
