The PureAir Treatment (PAT) is a unique application of ozone. Ozone is the ONLY thing that works on virtually ALL odor types. Lets consider a house with smoke "damage" from tobacco smoke or a house fire. The “smoke smell" is actually an on-going chemical reaction that is releasing low concentrations of long-chain combined chemicals. When the PureAir Treatment is introduce into the treatment area, the PAT molecules combine with the still-reacting smoke compounds. As the two mix, the reactive PAT molecules begin pulling apart the long-chain bonds of the smoke molecules, thus stopping the chemical process. PAT molecules are being consumed as the “fuel” to pull the long chains apart. The result of "pulling apart" the smoke odor molecule is reduced to a non-odorous compound.The odor is “dead”.
