a toilet seat having a hinge mounted to the base structure and centrally aligned to the upper rim; a toilet top lid mounted to the toilet seat via the hinge; a filter assembly including a high efficiency particulate air (HEPA) filter disposed within a porous and metallic filter track housing composed of, the assembly mounted to an underside of the toilet top lid, the filter assembly making uniform surface contact on one end with the top surface of the toilet seat when the toilet seat and top lid are closed; and an electronics compartment having an internal volume for containing electronics for initiating flushing, a power source for powering the electronics, and at least one visual indicia for notification of state; characterized in that a manual or electronically initiated flushing sequence with the toilet seat and toilet top lid closed forces contaminated air within the toilet water bowl to rise upon refilling of the water bowl from a connected source of water and to exit laterally through the filter assembly along the periphery thereof to the outside of the base structure. ### Claim 2 (depends on 1) The antiviral commode of claim 1, wherein a plumbed water tank serves as a connected water source and wherein a flush button is provided on the electronics compartment enabling manual flushing. ### Claim 3 (depends on 1) The antiviral commode of claim 1, wherein a plumbed electronic flushing unit serves as a connected water source and wherein flushing is initiated remotely via a wireless transceiver and a remote power switch contained in the electronics compartment. ### Claim 4 (depends on 3) The antiviral commode of claim 3, wherein flushing is initiated as a result of optical sensing of the closed state of the antiviral commode. ### Claim 5 (depends on 2) The antiviral commode of claim 2, wherein flushing is initiated by a user operating a remote control device. ### Claim 6 (depends on 1) The antiviral commode of claim 1, wherein the toilet seat includes at least two linear and annular one-way check valves seated laterally through the material of the toilet seat, the check valves allowing outside air to enter into the toilet bowl and preventing air inside the toilet bowl to escape back through the check valves to the outside of the base structure. ### Claim 7 (depends on 1) The antiviral commode of claim 1, wherein the visual indicia include two or more light emitting diodes (LEDs) mounted to the exterior of the electronics compartment for alerting a user to commode state including the state of water filling into the toilet bowl after a flush action. ### Claim 8 (depends on 1) The antiviral commode of claim 1, wherein electronics for initiating flushing include a remotely activated power switch. ### Claim 9 (depends on 1) The antiviral commode of claim 1, wherein the electronics include a micro controller having instruction thereon for indicating state via the one or more LEDs. ### Claim 10 (depends on 1) The antiviral commode of claim 1, further including an annular depression having a cross bar therein for serving as a lift handle disposed on the outside of the electronics compartment. ### Claim 11 (depends on 1) The antiviral commode of claim 1, wherein the electronics further include electronics for providing a negative electric charge to an inner track portion of the filter track housing and a positive electric charge to an outer portion of the filter track housing. ### Claim 12 (depends on 1) The antiviral commode of claim 1, wherein the power source is a rechargeable battery and wherein the electronics further include electronics for enabling the battery to be recharged. ### Claim 13 (depends on 12) The antiviral commode of claim 12, wherein the electronics for charging is a universal serial bus (USB) port. ### Claim 14 (depends on 1) The antiviral commode of claim 1, wherein the uniform surface contact between the top lid and the toilet seat is via a gasket installed on the free end of the filter assembly. ### Claim 15 (depends on 1) The antiviral commode of claim 1, further including a pair of polymer caps to cover the metal porous track housing on each end of the filter assembly.
