What is Ozone and what does it do?
Unlike many terms in the world of science, ozone is a word almost everyone knows. Some know that it creates that fresh feeling after a storm. Others remember that aerosols and refrigerants put a hole in the Ozone layer. But, very few people know what it really is and does to airborne particles. Ozone, whether created by a machine, a thunderstorm, or by the sun’s rays… is a molecule comprising three oxygen atoms. O2 is the oxygen that makes life possible for us humans, two atoms of oxygen are very important. Sometimes a third oxygen atom is present creating (O3) ozone, and it can detach from the O3 molecule, and cling to others, changing their chemical composition and weight. It is this ability that gives an ozone generator the ability to strip contaminants of any size from the air.
How does an Ozone Generator Work?
Replicating a process found in nature can be very complex. The sun and lightning are insanely powerful. So, creating ozone must be very difficult and technical, right? Well, sorry to disappoint… it’s actually very straightforward and to some extent, easy to do. Ozone generating machines, for the most part, suck in air which and pass it through an electrical charge. Kind of like lighting. After that, the air exits the machine with O3 molecules instead of plain old O2. Those ozone molecules are then free to deploy their extra oxygen molecule to neutralize contaminants. Maybe it’s an airborne virus, or mold spore, or smoke. Whatever it is when that ozone molecule finds it; game over.
1. Enerzen Commercial Ozone Generator
Small and compact the Enerzen air purifier can be used virtually anywhere to eliminate odors! It’s lightweight and portable, weighing in just under 6 pounds. And that isn’t the only reason this ozone generator should be your go to purchase. If you are worried about mold or fungus growth this machine will both control and remove those contaminants from your home. Its built-in timer will allow you to set up this little machine at home while you are away and return to odor free air. But, what is best about this model is its eco-friendly design which ends up saving you bundles on your energy bill. The ultra-low energy use combined with its still powerful deodorizer works to save you time and money all while removing any dangerous fumes and irritants. Use this machine to remove cigarette smells, pet odors, dust, painting fumes and more!
There are only two things to note about this little generator, the cord to plug it in is only 5 feet long and that after extensive use the unit will still function but develops a loud buzzing noise. That being said, for such a fantastic price, the quality of this long lasting unit is definitely worth the investment.
3. OdorStop Ozone Generators
Odor Stop makes great machines that cover a wide range of uses. From their affordable unit for small spaces, the OS600UV, to their wheeled OS12500 these guys have a generator for everyone. Over a dozen in total.
With that many machines you might wonder what differentiates each model. The biggest differences are in number of plates, UV bulbs, and ozone output. Single plate models are the smaller machines sized for area smaller than 2000 feet. Aside from the OS600’s the easy way to tell how many plates are included is to look at the first number after “OS” in the model designations.
That means a OS4500 would have four plates while a OS2500 would offer two. Any model with “UV” after the numbers includes either one, or two UV lamps to help kill bacteria and such. Though we’d recommend opting for the non-UV models.
With a heavy duty aluminum body and excellent fit and finish, it’s hard to go wrong with OdorStop. They even come with a five year warranty.

This unit also has a timer to turn on your machine when you leave the home. As with all ozone generators, you do not want to have it on in the room with you as it can cause eye irritation and breathing problems. The only complaint on this machine is to be sure that you are not in the room while running, as it is very powerful!

So what is the con to this machine? Some customers complain that the ozone function works almost a little too well. Even at it’s the lowest setting an odor can be produced if there is too much ozone, and after a quick 20 minutes you could find yourself with a new type of smell. However, if you buy a timer, you can make sure that your ozone setting shuts off in intervals that are appropriate for your house.
