An EMI filter for use with a motor driven blower connectable to an inflatable portion of a patient support powered by two supply lines includes a blower ground isolated from a chassis ground, a first capacitor coupling the blower ground and one of the two supply lines, a second capacitor coupling the blower ground and the other of the two supply lines so that the first and second capacitors cooperate to filter common mode EMI without the aid of an inductor. |
