In 1998, Chester "Buck" Weimer of Pueblo, Colorado received a patent for the first undergarment that contained a replaceable charcoal filter. The undergarments are air-tight and provide a pocketed escape hole in which a charcoal filter can be inserted.[16] In 2001 Mr Weimer received the Ig Nobel Prize for Biology for his invention.[17]
