The present invention provides an oxidant production apparatus, an example embodiment of which comprises a water container configured to accept and retain a volume of water; a porous salt container configured to accept and retain a quantity of salt, mounted with the water container such that salt in the salt container is in fluid communication with water in the water container; an electrolysis system mounted with the water container; and a gas directing element mounted with the salt container and the water container such that gas generated by the electrolysis system is preferentially directed through the salt container. In operation, gas from electrolysis percolates through the water and the salt, agitating the salt and encouraging the salt to fully dissolve.
