Abstract: There are more than sixty million cats in the United States according to the statistics of ABI Informer. My filtering system takes advantage of the facts that (1) air that has the odor of cats in it is slightly lighter than is air that does not have cat odor in it. (2) If air having odors in it are forced to change their direction of travel, the odor containing air will give up its odors. (3) Charcoal is an ideal substance to neutralize cat odors. Air saturated with charcoal will kill fleas, or make them to somewhere else to live.
