Fungal particles have been known to aggravate indoor air quality. To develop fungal particle cleaning devices requires a well-controlled generator of fungal aerosol particles. In this study, a novel fungal aerosol generator was designed and tested for anti-fungal experiment. Cladosporium cladosporioides was selected as test fungal particle. After aerosolization, the number concentration and the size of particles were measured by aerodynamic particle sizer. The number concentration depended on the vibration strength and vibration period of the designed fungal aerosol generator. For the vibration strength of 10volt and the period of 10 sec (5 sec on and 5 sec off), the stable particle generation with concentration of 10#/cm3 was maintained during 35 minutes.
