That's not exactly how a sponge filter works. The air does not push anything. The rising air bubbles create a vacuum behind them, which pulls water up into the void left behind. The vacuum created by the bubbles in the center of the sponge (and in the tube like thing) is what draws the water into the sponge, filtering it.
Don't mean to nitpick, but words have meanings and there is right and wrong with regards to physics.
