Patent attributes
A filter assembly adaptable to various air moving systems, including HVAC units and portable fans, comprises a lower frame with a flexible mesh that, along with the frame's perimeter, encloses a volume containing particulate filter media. This media filters air while producing an audible noise indicating system operation. The upper frame, attachable to the lower frame, includes a mesh bottom and houses scenting materials to enhance air quality with fragrances, designed to prevent these materials from escaping during use. Both frames feature mechanical fasteners for easy mutual attachment and maintenance. The upper frame's mesh side is partially removable for management of scenting materials. This filter assembly offers both functional air filtration and optional air scenting, providing a versatile and user-friendly solution for improving indoor air environments.
