Abstract
A drain pan is provided for removing copper ions from condensate water produced by a heating, ventilation and air conditioning unit. The pan defines a volume having two closed ends and an open top so that water can evaporate from the pan. At least one copper removing agent is placed in the pan, and a baffle is provided between the ends of the pan, for routing water entering the pan at one end through the removing agent en route to an outlet at the other end. The removing agent may include mossy zinc and/or activated charcoal.
