A fan assembly includes a tubular housing and electrodes which ionize air and cause the air to be filtered and to move through the tubular housing without use of moving parts, such as an impeller, thereby providing air filtration and ventilation without generation of vibrations and acoustic disturbances. An electric potential is applied between a longitudinally-oriented needle electrode and a planar or curved transversely-oriented net electrode disposed within the housing downstream of the needle electrode, thereby forming a longitudinally asymmetric electric field that ionizes and accelerates air molecules toward the net electrode, carrying the air molecules past the net electrode and through the air outlet. The assembly further includes a tubular duct electrode disposed within the housing on the outlet side ofthe net electrode, which collects ionized particles precipitated from the air. A conducting pivot, which is electrically connected to the net electrode, extends coaxially with the tubular duct electrode along at least a portion of the tubular duct electrode in the longitudinal direction and facilitates precipitation of the particles. The duct electrode can be removed and cleaned or replaced.
