## Abstract

This invention pertains to interchangeable, disposable, air filtration pads, which work in conjunction with its double-sided flexible magnetic gaskets and mats. This system works both for return and supply side of the HVAC system. This multi-adaptable double-sided magnetic mat system is easily attachable and removable and compatible to current factory vent plates, and HVAC systems.

## Claims

### Claim 1

An HVAC filter comprised of a frame and a filter;
the frame is dimensioned to completely cover a predetermined grate on an HVAC system;
the frame has an margin that is in continuous and airtight contact with the grate;
the frame includes a series of apertures inside the margin that allow an airflow to pass through the frame;
the filter is dimensioned to match the dimensions of the frame;
the airflow passing through the frame must pass through the filter;
the filter is electrostatically charged;
the filter is configured so that an airborne particulate is captured and held by the filter.

### Claim 2 (depends on 1)

An HVAC filter as disclosed in claim 1 further characterized in that the frame includes an adhesive layer on a side in contact with the filter to secure the filter to the frame.

### Claim 3 (depends on 1)

An HVAC filter as disclosed in claim 1 further characterized in that the filter includes activated carbon to filter out vapors dissolved the airflow.

### Claim 4 (depends on 1)

An HVAC filter as disclosed in claim 1 further characterized in that a gasket is provided to ensure an airtight seal between the grate and the frame or the filter and the frame or the filter and the grate.

### Claim 5 (depends on 1)

An HVAC filter as disclosed in claim 1 further characterized in that the frame is attached to the grate by any of: screws, clips, magnets, snap on fit or friction fit.
