They Invented What? (No. 135)

Posted in They Invented What? by Jake Ward on April 8, 2009

U.S. Pat. No. 3,234,948:  Cheese-filter cigaret.

JW Note: The inventor observes that “it is preferred to use a hard cheese as exemplified by Parmesan, Romano or Swiss cheese . . . [however] Aged Cheddars and other “hard” cheeses may also be used”.


I claim:

1. A cigaret filter capable of reducing materially the nicotine and tars in the tobacco smoke, said filter comprising small, well-defined porous particles of hard milk derived cheese having a fat content in excess of 20 percent but being sufficiently dry so that most of the fat is in the interior of the individual particles on the surfaces constituting the walls of pores with which the individual particles are provided and within which filtering occurs.
