Abstract
Compositions, methods and apparatuses for reducing or eliminating malodors from indoor air are described. The method utilizes vapor phase hydrogen peroxide (VPHP) generated from either evaporation from an aqueous-based liquid composition or sublimation from a solid hydrogen peroxide-containing compound. VPHP engages a media coated with at least one transitional metal element or compound, which acts as an oxidation catalyst, in the presence of air that contains malodorous compounds to provide increased efficacy of malodor molecule oxidation. The apparatus can employ a disposable porous non-woven filter pad coated with one or more transition metal compounds, and a solid source of VPHP. Malodor-containing air engages the pad in the presence of the VPHP to effectively oxidize the malodorants. The apparatus can also include a mechanism to provide color change(s) in the presence of VPHP to indicate whether the device contains VPHP or not.
