Ventilation filter mechanism
First Claim
1. A filtering system comprising:
- a frame having at least one opening therethrough and a flange, wherein the flange is adapted to be secured to an air register such that said flange encircles an outlet of said air register, an air filtering material contained within said frame such that when said flange is secured to said air register, air flow from said air register must flow through said air filtering material to enter a room serviced by said air register; and
a register mechanism securable to an exterior surface of said frame, said register mechanism being manually manipulated by a user to direct a flow of air into said room.

Abstract
A filtering system which is secured to a traditional air register. The filter uses a flange adapted to encircle the outlet of the traditional air register. Connected to the flange is an air filtering material which collects the dust and pollen at the air register, before the air enters the room. In one embodiment of the invention, an electro-static charge is used by the filtering material to assist in the collection of the dust and pollen. To assist the user in determining when the filter system should be replaced, the air flow pushes a flag; hence as the air flow decreases as the filter becomes clogged, the location of the flag notifies the user that the air filter system should be replaced. While a hook-and-loop fastener is sometimes used to secure the filter to the air register, the preferred embodiment uses a releasable adhesive.
