The embarrassment of passing gas in public is ubiquitous. One solution is to wear a filter underwear that is generally constructed with a single ply of underwear side panels that are separated by an activated carbon center panel. The activated carbon center panel is attached to an elastic waistband at the underwear back and where the activated carbon center panel traverses between two leg openings to the waistband at the underwear front. The center panel is constructed with a five-ply activated carbon fabric that is sandwiched between cotton fabric, which is sandwiched between bamboo fabric. The five-ply center panel is greater than 1 mm thick to provide filtering capabilities to sufficiently reduce the odor of flatulence to an acceptable level that is not readily detected by a person close by.
