PURPOSE: To provide a ventilating device provided with a filter permeated with hinokitiol capable of preventing bacteria infection. CONSTITUTION: Liquid chemicals of hinokitiol is flown out little by little to a filter 7 from a storing cage 9 through a pipe 10 using a fall. Then, the liquid chemicals permeate through the net part of the filter 7 due to capillarity so that the whole part of the filter 7 becomes wet. Under this state, a fan 3 is operated and outside air in which bacteria is included passes through the filter 7 mounted on an inlet port 5, the bacteria included in the outside air is killed. Sterilized outside air is exhausted from an outlet port 6 as fresh air. |
