Clean screen air filtration system

摘要

A clean screen air filtration system for increasing the filtration of allergens, dust particles, and airborne pollutants from air exiting an air duct. In a preferred embodiment, a user may removably attach a clean screen air filtration system assembly to an existing air duct via a magnetic fastening strip affixed along a backside of an air filter frame. The magnetic fastening strip may provide an efficient means for removably attaching the clean screen air filtration system assembly to the outside of an existing air duct manufactured from a metallic material. The clean screen air filtration system assembly may comprise at least one replaceable air filter. The air filter may comprise a ventilation screen having a plurality of miniature, slatted filter apertures, a flexible air filter frame, and an air filter handle/tab. The user may slidably insert air filter via the filter handle/tab into a filter track located inside a gap region integrated within the air filter frame. The gap region may comprise a width and depth just large enough to receive the air filter such that only the filter handle/tab extends beyond the air filter frame for ease of replacement.

主权项

1. A clean screen air filtration system for removable attachment to an air duct, the clean screen air filtration system comprising:
at least one unitary-body air filter comprising a ventilation screen attached to and peripherally framed by a siding having a handle at one end of said siding; an air filter frame comprising having a single airflow opening and a filter track configured to slideably receive said unitary-body air filter, wherein, when attached to an air duct, said airflow opening substantially overlaps an opening of said air duct, wherein when said unitary-body air filter is fully inserted into said filter track, said handle of said siding projects from said filter track; and a magnetic fastening strip affixed to the backside periphery of said air filter frame, wherein said magnetic fastening strip is configured to substantially align with and removably attach to along all four back sides of a magnetically-permeable peripheral frame of an air duct, wherein said ventilation screen has filter apertures sized to reduce the passage of allergens, mold, dust, and other airborne particles and pollutants from exiting said single opening of said air filter frame into an interior room.
