Polymer or polymer inks are used for reducing or eliminating harmful chemicals by offering a neutralizing chemical in the path of movement of the harmful chemicals. A neutralizing chemical responsive to the harmful chemical produces a harmless chemical as an output that is in the path of the harmful chemical and is opposite phase with the neutralizing chemical, preferably by 180 degrees, or is at least opposite in chemical compatibility to some extent. The neutralizing chemical can be suspended or combined with an inert carrier and preferably attenuates the harmful chemical concentration. The polymer ink can be applied to a media such as paper, (embossed or extruded) or polymer the same as paper but also in foam (open cell preferred) in order to obtain a decrease in the concentration of harmful gases. These forms can be utilized in air or liquid applications.
