An anti-contamination system having a container, a pump, a tube, an exhaust pipe, and a dispenser system. The pump is used to direct a water and calcium oxide solution through the tube to the dispenser system. The high temperature of the exhaust gases is used as a reactor and the exhaust pipe as a controlled atmosphere volume. The heat from the exhaust gas/pipe is used to heat water mixed with calcium oxide to create calcium hydroxide and steam, which is injected by the dispenser system into the exhaust pipe such that the exhaust gas reacts with the steam and the calcium hydroxide. The exhaust pipe is made with stainless steel to avoid corrosion due the chemical reactions that occur inside, and the gases expelled to the atmosphere are clean with only minimal solid residues like calcium sulfate that are troughed away as small pellets, without any pollution contribution.
