How We Chose the Best Ozone Generators 

We researched the most sought-after ozone generators in their respective categories and discovered that the best models are determined by their type, ozone production levels, size and weight, and special features included by select brands.

While searching for the best ozone generators available, the cold plasma options proved to be the most popular for their ease of use and effectiveness. Though not as popular, the ultraviolet option included is also a viable option for its high ozone emission and allergy-control capabilities. No matter the type, our picks list features options with 50 to 20,000 milligrams per hour (mg/hr) ozone emission levels depending upon the space and preference.

The vast majority of our picks are also compact and lightweight enough to be transported or moved from room to room. Finally, in the interest of choosing the best options on the market, our picks also come with built-in timers, multiple ozone output and fan levels, handles, and long runtimes of up to 3 hours.
