Abstract: The present device is a suppression device for containing sound and germs emanating from a user's cough. A substantially hollow tube forms a gas conduit with a gas-permeable end membrane fixed within the tube across the gas conduit. A layer of a gas-permeable anti-bacterial material is fixed within the tube against the end membrane and a gas-permeable filter material is fixed within the tube against the anti-bacterial material. When a user needs to cough, the user coughs into the suppression device whereby the emanating germs and sound are suppressed as they encounter the filter material, the anti-bacterial material, and the end membrane. The suppression device further includes a lanyard permitting a user to wear the device and a label to write the user's name on the device. The suppression device is primarily comprised of biodegradable materials, allowing the suppression device to be disposable in an environmentally friendly way.
