摘要：

PURPOSE: To provide an air cleaner processing the output of a dust sensor, detecting even a small amt. of dust with precision and without any malfunction. CONSTITUTION: The output of a dust sensor 1 is inputted to a microprocessor 2 directly or through an amplifier 3, and the inputs are selected in the microprocessor 2. When the amt. of dust is small, the output is inputted through the amplifier 3, and, when the input is large, the output is directly inputted. Further, the revolving speed of a motor 5 is determined based on the value, and the lighting of an indicating lamp in an indicating circuit 6 is also determined.
