An interfloor noise reduction panel with an air purifying function for buildings is capable of reducing impact due to the dropping of a weight and electromotive forces of machinery as well as noise and vibration transmitted through the floor of the building through the structure in which a plurality of springs, a sound-absorbing material, an ion mortar layer are disposed in a base panel such that noise generated by pressure applied to the panel above is absorbed and thus maximally extinguished.
