Abstract: The present disclosure provides a chlorinator apparatus for installation in the drain line of an air conditioning unit such as a household HVAC unit. The chlorinator apparatus is configured to hold a stack of tablets in a chamber such that they are partially submerged in a flow of water running through the drain line, thereby steadily dissolving in the flow and providing a long term blockage solution of the drain line, removing the need for regular application of bleach and other chemicals and preventing water build up and damage to the AC unit.
