As an advocate of ozone solutions, it is possible to be closed-minded about something that competes with ozone. However, the premise is "Environmentally-Smart Solution" rather than one idea that ignores all else. In fact, I have tried to be open-minded about all non-chemical solutions to the common problems we face.
Odor removal is not an exact science. To be frank, you cannot make badly used carpet into what like was when new. The nature of a remediation service is to restore the house, carpet, room, or furniture back to its best condition.
Professional ozone services may know how long to run an ozone generator, but most people are ill-informed about the length of time to run an ozone generator.
As you may remember for high school science, water is H2O, meaning two oxygen atoms are stuck to one hydrogen atom. This makes the oxygen less available than the normal O2 in the ambient air. Air conditioning solves the two variables to ozone production: temperature and humidity.
While the EPA has warned about ozone problems, it should be understood that there are hundreds of ozone applications that make our lives better. Every good thing can be abused and misused, and ozone is no different. Knowing that the are mistakes to avoid, there is a need apply ozone in ways that solve problems without introducing a variety of chemicals that are serious pollution issues themselves.
One of the best-known ozone treatments is odor removal. But, there are hundreds of reasons for odors that requires an understanding of odor types and the dynamics of treating different materials.
Ozone treatments have grown in popularity for twenty years. Ozone training is a necessary requirement for any ozone service worker.
There is a lot of promotion of the superiority of the UV ozone generators versus corona ozone generators. Getting a good read on the two types of ozone generators will be helpful. Having been around ozone for a long time and used both types, this quick review may prove helpful to those yet undecided.
To state the issue properly, there are two sides to the question of the smell of ozone. There is the concern for ozone DURING an ozone application, and another aspect for the lingering ozone smell AFTER the room air has been normalized.
