Ford Motor Co. and Young & Rubicam, New York, have agreed to settle Federal Trade Commission charges that Ford's advertising overstated the extent to which a new filtration system removed air pollutants. The ads for Lincoln Continental and Mercury Mystique began running in February 1995. For Y&R, the FTC action is a second slap on the wrist on a similar subject. In 1985, Y&R agreed not to exaggerate claims for household air filters. While the FTC has previously targetted claims for indoor air filters and purifiers, the action is the first for automobile filtering systems.
