A system and method for removing sulfur-containing contaminants from indoor air includes a panel system having a first layer and a second layer. The first layer can include a base media onto which sodium bicarbonate is attached. The second layer can include a base media onto which activated carbon is attached. Indoor air including sulfur-containing contaminants can contact and pass through the first layer. Sulfuric acid can react with the sodium bicarbonate to produce sodium sulfate, which can, in turn, act as a drying agent for organic sulfur-containing contaminants in the indoor air, such as carbon disulfide and carbonyl sulfide. As a result of such drying, the second layer can more effectively trap and/or bind (adsorb) the organic sulfur-containing contaminants so that these contaminants are removed from the contaminated air. The treated air can be returned to an indoor space of the structure.

What is claimed is: 1. A panel system for removing sulfur-containing contaminants from indoor air comprising: a first layer having a base media and sodium bicarbonate associated with the base media, the first layer being configured to allow air to flow therethrough, whereby, when a gas flow including sulfuric acid and sulfur-containing contaminants passes through the first layer, the sulfuric acid chemically reacts with the sodium bicarbonate to produce sodium sulfate, water and carbon dioxide, whereby the sodium sulfate acts as a drying agent for the organic sulfur-containing contaminants by adsorbing at least a portion of the water produced in the chemical reaction; and a second layer having a base media and activated carbon associated with the base media, the second layer being configured to allow air to flow therethrough, the second layer being operatively positioned relative to the first layer, whereby, when the gas flow exiting the first layer passes through the second layer, at least a portion of the organic sulfur-containing contaminates is adsorbed by the activated carbon, whereby the level of the sulfur-containing contaminants in the gas flow leaving the panel system is less than the level of the sulfur-containing contaminants in the gas flow entering the panel system. 2.
