The invention relates to an argon blowing and gettering filter for a continuous casting tundish and a working method of the argon blowing and gettering filter, the argon blowing and gettering filter is arranged at the lower part of a tundish retaining wall and consists of a filter body, an inclusion adsorption filtering channel and an argon blowing ventilation element; the inclusion adsorption filtering channel is arranged in the filter body, and two ends of the inclusion adsorption filtering channel are respectively communicated with the impact area and the pouring area; the argon blowing ventilation element is arranged in the filter body and located at the molten steel inflow end or the molten steel outflow end. The device comprises two adsorption mechanisms, namely an inclusion adsorption filtering channel adsorption inclusion and an argon blowing ventilation element argon blowing adsorption inclusion, so that non-metallic inclusions with different sizes can be effectively removed, including tiny inclusion
