High ozone shock treatment or ozone blasting is the process of removing unwanted odors, and killing fungi, pests and microorganisms in commercial and residential buildings. This treatment is cheaper than some alternative methods to sterilize indoor space - cleaning or disposing of building materials, or in extreme cases leaving sick buildings.

Process
High ozone shock treatments involve the use of an ozone generator with a timer to create a deadly ozone level in a room or building covered by a fungal odor or space for a short time, between one and several hours. For security reasons, the affected area should be evacuated by people, animals and plants alive during the exposure period, and for a considerable length of time thereafter to allow ozone to disappear.

Results
The high level of ozone exposure kills living organisms and weakens the odor.
By killing microorganisms and fungi, ozone treatment slows down maturation and reduces the decay of stored fruits.
Worries
Critics point to a 1997 study that found exposure to high levels of ozone was not effective in mold decontamination, and the lack of research showing high ozone shock treatment became effective. They also point out that murder mold inside the walls does not remove mold, and the die mold may continue to have an adverse effect on the health of building occupants. Since then there have been many other studies that confirm the effective use of ozone to kill fungus along with other remediation techniques.
Ozone is a powerful oxidizing agent that can damage rubber and other materials, and the reaction of ozone with the presence of other materials in buildings can lead to increased levels of harmful chemicals such as formalin.
