Do Ozone Machines Really Work? January 29 2018, 0 Comments

Ozone has a diverse range of uses, however the benefits of this natural marvel are not widely known. An abundance of misinformation about ozone has also contributed to its sometimes negative reputation. When first beginning to research ozone, many may ask, does the ozone machine really work? This post will compile scientific research that has documented the oxidizing power of ozone firsthand, while also looking towards its future applications.


Scientists from Viroforce Systems in Vancouver, Canada studied the effectiveness of ozone as an anti-fungal agent.

In the study, the scientists list several advantages of ozone over alternative liquid mold treatments:

  • Easy and cheap to produce from air or oxygen
  • Ozone diffuses quickly into all parts of a room, including cracks and crevices
  • Although toxic at high doses, ozone dissociates naturally to oxygen (326)

To test the practical use of ozone for this application, the researchers utilized their own proprietary ozone machine, the ViroForce 1000, which creates ozone with cold corona discharge technology. The study collected 13 different species of environmental fungi from derelict buildings in the area. In a test environment, the researchers applied 20 minutes of ozone exposure in a polycarbonate test chamber to the strands. Ultimately, they concluded, “the ozone generator would be a valuable decontamination tool for mold removal in buildings.”


Another study examined the effectiveness of ozone as an anti-bacterial agent. The researchers, with the University of British Columbia, studied the impact of ozone in the test environment on 15 different types of medically important bacteria. 

In their study, the researchers acknowledge some drawbacks of methods of disinfection that are currently utilized, "Such methods have inherent drawbacks, including high cost, labor-intensiveness, and potential for inhalation of disinfectant vapors by hospital staff, formation of dirty flecks on glass surfaces, and retention of unpleasant disinfectant odor after decontamination."

Ozone decontamination has been shown to have substantial advantages over other decontamination methods:

  • The gas can effectively penetrate every part of a room, including sites for which access is difficult using conventional liquids and manual cleaning procedures
  • It can be switched on and off from the outside after the room has been made airtight
  • Ozone has known antibacterial activity, can be generated cheaply, and, although toxic, rapidly dissociates to oxygen, with a half-life of about 20 minutes

They concluded that the, "inactivation of bacterial samples dried onto plastic, confirming that ozone gas can be bactericidal to samples on curtains, linen, furniture, and walls in health care facilities."

  • Whereas wiping with liquid disinfectant for general decontamination requires much work and is unsuitable for curtains, walls and ceilings, decontamination with gas is quick, easy, and suitable for soft surfaces
  • Dry and wet samples demonstrated equivalent sensitivity to ozone
