One study conducted by Manju Sharma and James Hudson of Vancouver, Canada took samples of 12 types of bacteria and utilized a gas ozone generator, similar to the Powerzone from Scandia, to render them ineffective. They specifically looked at the possibility: could ozone gas be used to sanitize hospital rooms?
Standard procedures for the sanitation of hospital rooms, or any space that has recently been exposed to a contagious illness, can be time consuming, toxic, expensive, and unfortunately foul-smelling. Even after which, some areas of the room may go untreated. The advantage of utilizing an ozone generator is that the O3 gas that is released envelopes the entire room. It can permeate all surface types, including fabrics, to break down bacteria before dissipating back to O2.
Having such an effective way to kill bacteria (and viruses too) could be utilized in other vacant spaces in hotels, cruise ships, schools, and offices. It is a low cost and low maintenance option with high efficacy. It can reduce exposure to those cleaning infectious areas and is far safer for handlers involved. Ozone must be deployed in a vacant space as it is an irritant to breathe, but it breaks down to breathable O2 around thirty minutes after use.
