Chlorine dioxide in gas or liquid form is an extremely effective disinfectant, which rapidly kills bacteria, viruses. ClO₂ also improves taste and odor, destroys sulfides, cyanides, and phenols, controls algae, and neutralizes iron and manganese ions. It is an effective biocide at concentrations as low as 0.1 ppm (parts per million) and over a wide pH range.Chlorine and chlorine dioxide are both oxidising agents (electron receivers). Chlorine has the capacity to take in only two electrons, chlorine dioxide can absorb five electrons. This means that, mole for mole, ClO₂ is 2.6 times more effective than chlorine.
ClO₂  is far safer, more pleasant, and more effective. Marvelzap sytem utilizing the  ClO₂ to provide the most efficiant odor elimination and disinfecting solution on the market.
