How to Choose the Right Ozone Generator

Ozone generators are practical tools for odor removal, surface disinfection, and air purification. However, with so many models available on the market, you should take the time to choose the right one. This blog post will discuss the most important things you should consider before you select an ozone generator.

Buy The Right Size Generator

The size of the area you plan to treat is a very important consideration, since you want to match up with the right generator to ensure the correct concentration of ozone in the air. So, a larger treatment area will require a larger generator. Most generator manufacturers offer multiple generators with different ozone outputs to treat different size areas.

Make sure your vendor provides easy guidelines to tell you how long to treat a specific sized area. Professional recommendation for an ozone shock treatment is 1,000 mg of Ozone output for 100 square feet of space with 10-foot ceilings or 1,000 cubic feet. Treatment times vary based on the severity of the pollutants and the nature/design of the space.

Type of Ozone Generator

Two main types of ozone generators exist, UV and corona discharge. UV ozone generators use ultraviolet light to produce low levels of ozone and were originally used in room air purifiers. They are not designed for shock treatments which are required for effective deodorization and surface disinfection.

Corona discharge generators use high voltage to create ozone and are more effective for both deodorization and surface sanitation because of their higher ozone output. Corona discharge is the preferred method used by professionals and is appropriate for both residential and commercial applications.


As noted above, ozone generator’s output determines the ozone concentration in the area being treated. The output is measured in milligrams of ozone per hour (mg/h) and indicates the amount of ozone being produced by the generator. Be sure to compare the outputs of the generators you are considering, and don’t overpay for a generator that doesn’t deliver!

There are some manufacturers that make wild claims about the area their generators can treat, without identifying what their output is in mg/hour. Be leary of any vendor that doesn’t list the actual ozone output of their generators! They tend to over promise and under deliver.


The timer allows you to set-up a generators treatment protocol, then safely exit the room before the generator starts discharging ozone. Look for a timer that will allow you to pulse the ozone delivery, as effective protocols require this feature to achieve success, and most generators aren’t capable of pulsing ozone output. Remember, No People, No Pets, and No Plants should be in the vicinity of an operating ozone generator. Timers also turn off the generator before re-entry.

A remote control really forces you to babysit the treatments, essentially keeping you tethered to the generator while it is in operation. The best approach is to use a timer that will make the treatments “hands-off,” so you can leave the area while the ozone generator automatically goes through the programmed cycles.


Seek out ozone generators that require little to no maintenance, and that have economical repair costs. A well-designed generator should work effectively and efficiently and provide long service life to help you maintain a healthier indoor environment. Always operate an ozone generator in a dry environment to prolong the ozone plates in the unit. Avoid generators with expensive filter systems, as it is all about dispersing pure ozone into the treatment area, not to filter the air!


The warranty protects your investment and provides peace of mind in the event of a problem with the generator. If there is a problem with the generator during the warranty period, the manufacturer will repair or replace it based on the terms of the warranty.

A longer warranty period is generally better, as it provides more protection for your investment. It is essential to read the terms of the warranty carefully to understand what is covered and what is not.
