PROBLEM TO BE SOLVED: To provide an air filtering apparatus that can suppress occurrence of scale in an electrolysis process, so that an interval time required for water exchange can be set to a long value. SOLUTION: The air filtering apparatus that is equipped with an air blower 21 and a gas-liquid contact member 31 in a housing 10 and in which electrolytic water is brought into contact with indoor air sucked by the air blower 21 to filter the air and then the filtered air is blown out to an indoor space, and further comprises: a water supply tank 41 for stocking water; a water receiving tray 44 for temporarily stocking water flowing out from the water supply tank 41; a circulating pump 42 for pumping up water stocked in the water receiving tray; an electrolytic water generator 43 for generating the electrolytic water from the water pumped by the circulating pump; and a circulating passage for circulating the electrolytic water through the gas-liquid contact member 31 and the water receiving tray 44 in this order. An ion exchange resin pack 100 for adjusting the hardness of water is provided in the water supply tank 41 located out of the circulating passage of the electrolytic water.
