The experiment isn't bad - but the most important factor was overlooked: Of course alcohol kills everything, but can you also fill the carpet, the couch, groceries or entire rooms with alcohol? If so then cool!! I've been using ozone generators in rooms, fridges, and trash cans almost every day for years. So everything is odorless. You simply have to use ozone generators more often so that it can effectively go in anywhere and do its job. ❤

Also, ozone does a lot of other things. Just like hydrogen peroxide, it is unstable and releases a hungry oxygen atom that wants to immediately bind to the first thing it finds. It essentially attacks and destroys pretty much every type of biological matter. It will kill anything -- cells, viruses, spores. It might not be effective against organisms that evolved antioxidants (for example green plants, algae, etc.) It will also destroy or deactivate pretty much all organic substances that have smell. So you can run it in a smelly room and if you do it for long enough at high enough concentration, you will get rid of all smells provided oxygen is able to penetrate everywhere.

at least you passed. remembering long words is hard.

The concentration of the ozone is also a factor here. Just looked up the ozone machine model here and it seems its 10,000 mg/hr. Of course how long you run the machine for and whether the area is sealed closed are variables. As you mentioned the ozone machine is great for areas you aren't going to clean by hand anyway so technically you could sanitize walls and ceilings and other objects in a room all at once which wouldn't have gotten touched by any cleaning agent at all most likely. Interesting experiment. Just grabbed a 20,000 mg/hr unit. Thanks!

He used a TERRIBLE method. Ozone takes a minimum of 3 hours to kill microbes. He probably know that sadly.

Good work! I have an ozone generator that maxes out at 12000 mg of ozone per hour and I expose items for no less than an hour to 12. I go scorched earth with it! I also have an ambient air ozone meter to monitor any leaking ozone levels at the exterior of the room where the sanitizing is taking place. Then, I use it for screening the room for safe levels, subsequently to venting the space for a reasonable period time or more, before allowing any physical activity within the area. Caution! Ozone generators don't only produce ozone. They also produce other energetic isotopes of other elements and gaseous compounds from the atmosphere including nitric acid fumes. The ozone and the other energetic isotopes and compounds will attack and have a corrosive effect on many exposed metal surfaces and polymers (Plastics) if saturated for long enough. The rubber feet of my generator crumbled away after my third heavy run, while fumigating a room full of contaminated items. Ozone must be treated with the utmost respect, care, and descension! Please stay safe!

Great info! My conclusion is: Ozone is good for large areas in general, Clorox for surfaces we touch.

Hate to comment on an older video, but did someone already mention that in addition to chemical sterilization, the clorox and alcohol pads also benefited from PHYSICAL sanitation?

The clorox wipes have a residue that continues to kill microbes for a while, especially before it is dried fully. The alcohol is also aqueous and will continue to kill until it completely evaporates. The ozone only works in the chamber and will not have any effect on anything encountered out of the chamber. I’d be curious to see what the result would be with an aqueous ozone solution.

Actually, ozone works great in larger areas from vehicles to commercial sized buildings as long as all doors and windows are shut. Ozone dissipates at an expedential rate so you must have a strong enough generator (s) that can produce enough ozone (parts/million) to achieve super sterilization. The issue is most non commercial ozone generators do not have the power to reach super sterilization.

O3 is an oxidizer. Some things are more resistant to oxidation than others. It’s not a disinfectant, it just acts as one. Kind of like how alcohol isn’t a 100% sterilizer either. Alcohol doesn’t necessarily kill all microbes either.

I think you need to find the threshold at which O3 is effective, also spraying the O3 box chamber with H2O2 to increase the O2 concentration could be another arm of the study. I use O3 to take the stink out of my boots in a sealed cardboard box with after spraying the boots with H2O2. For me no other disinfectant has been as effective as the O3 generator. Off course I leave the boots in overnight after running the machine for 30 or so mins

One concern is that when ozone is use in actual practice the application time is longer and the time following the application is longer. In this case you also measured the speed at which each cleaner acts on bacteria. While the exposure time for the ozone in the box may have been OK the time allowed after exposure to ozone was not in line with the typical use. Maybe an hour or more after exposure may be useful before checking the ozone results.
