If you’re looking to purify your air, look no further than the ozone generator. 

Designed to “clean” your air and remove strong odors, ozone generators have increased in popularity over the years.

So, how exactly do ozone generators work, and what makes them effective? 

Ozone is composed of three oxygen molecules. Although we breathe oxygen, we don’t breathe ozone. We breathe dioxygen, which is made up of two oxygen molecules. 

In scientific literature, ozone is referred to as trioxygen. Due to the instability of its third oxygen molecule, it’s only loosely connected with the other two molecules. 

Thus, it can easily attach itself to other particles, including viruses, bacteria, organic matter, mold spores, and pollutants such as smoke. When it attaches itself to pollutants like these, the substance gets destroyed. 

It’s this ability to attach to other molecules that allows ozone to deodorize and clean indoor spaces relatively quickly. 

And thanks to the ozone generator, which releases ozone into the atmosphere, you can now effortlessly make your spaces, from your home to your vehicle to your office, clean and odor free. 

Here are some of the best ozone generators on the market to date. Although they vary widely by size and capability, they’re all designed to purify the air and give you the clean and odor-free space you’ve always wanted. 

Read on for more information about these innovative machines.
