An apparatus (100) includes an air path housing (10), a charging-unit high-voltage electrode (2) to charge airborne microorganisms introduced in the air path housing (10), a charging-unit ground electrode (3) disposed so as to face the charging-unit high-voltage electrode (2), a hydrophilic filter (6) to capture the airborne microorganisms charged by the charging-unit high-voltage electrode (2), a capturing/inactivating-unit high-voltage electrode (5) to polarize the hydrophilic filter (6), and a capturing/inactivating-unit ground electrode (7) disposed so as to face the capturing/inactivating-unit high-voltage electrode (5).
