Maimonides
That purification from all kinds of defilement shall be effected by immersion in the waters of a Mikvah, as it is said, “…. then he shall wash all his flesh in water” (Lev. 15:16). It has been learnt by tradition that this means that the washing must be in a sufficient quantity of water, so that the entire body is totally immersed at one time.
