PROBLEM TO BE SOLVED: To provide an air cleaning/ventilating device that can appropriately remove dust while restraining power consumption.SOLUTION: An air cleaning/ventilating device 10 comprises a suction port 11 communicating with the outdoors, first dust separation means 1, a first duct 3, second dust separation means 2, a second duct 4, and a third duct 5. The first dust separation means 1 removes first dust from air sucked via the suction port 11. The first duct 3 makes the downstream side of the first dust separation means 1 communicate with a living space 50. The second dust separation means 2 removes second dust smaller than the first dust more efficiently than the first dust separation means. The second duct 4 branches from the downstream side of the first dust separation means and communicates with the second dust separation means 2. The third duct 3 makes the second dust separation means 2 communicate with the living space 50. Suction means 20 can suck air from the suction port 11 and adjust the ratio of air flowing into the first duct 3 and the second duct 4 respectively. |
