ABSTRACT:
The germ and noise filter device is a disposable, hand held filter apparatus that covers the mouth of the user during the exhale phase of a cough. The device comprises: a body with a cavity that houses three micro-filters; a corrugated tube; two one-way valves and a mesh screen. The body can be made of durable plastic material that may be transparent or a combination of many attractive colors. The two one-way valves act as a filter element for the noise that would normally occur. An eyelet is formed on the body to allow the device to be worn about the person. When a cough is eminent, the opening of the device is engaged against the user lips to prevent the transmission of air-borne diseases and reduce the noise of the coughs.
