Best Ozone Generator for Odors
Ozone generators make up a subclass of air purifiers that rely on their namesake ozone to combat odors and inhibit germs, mold, and mildew.
Ozone generators are considered best-in-class when it comes to deodorizing spaces as they’re able to neutralize all sorts of malodorous smells easily, but ozone is known to be harmful to humans and animals.
Ozone generators can be a gold mine if used correctly. To help you pick the right model, this article lists the best ozone generators available on the market.
Following this list is a brief Buyer’s Guide explaining the strength of these machines and how to safely use them as well as some frequently asked questions and our pick for the best option in this category.

Our first ozone generator offers the highest overall output, as well as the best coverage.
The VIVOSUN Industrial Commercial Air Purifier boasts a whopping 10,000 mg/hour of ozone production, which will quickly enable homeowners and small business owners to purify their spaces in a far shorter amount of time than options with smaller outputs. Because of this, the VIVOSUN can also tackle rooms and spaces up to 4,500 square feet.
Plus, at well under $100, This ozone generator is one of the cheapest on our list. Aside from a short timer length and some issues with the quality of the housing, VIVOSUN proves to be a formidable player in this field, and more than capable of providing for your ozone needs.
- High capacity
- High room coverage
- Hold feature
- Short timer length
- Some quality control issues with housing
If you need the air purification options included in the VIVOSUN model but need a more affordable design, the Concise Home CH-0021 offers many of the same features and purification options at a reduced price.
Using the included two hour timer, you can expect up to 5,000 mg/hour ozone production–and while the manufacturer doesn’t offer a specific room size capacity for this model, it’s safe to assume that you’ll be able to cover smaller homes and apartments with relative ease. Plus, the included cotton filter will provide some basic filtration as well as air purification.
We appreciate the sturdy, heavy-duty design that’s sure to outlast this product’s three year warranty. However, the lack of hold feature can be a bit of a health concern–as you’ll need to re-enter the space every two hours to get the generator back up and running.
Otherwise, for the cost, this generator will do just nicely for low-volume needs.
- Sturdy design
- Good warranty
- Basic filter included
- No hold feature
- No extra ozone plates or features
For a more residential option that comes with more than one ozone plate for extended use, Airthereal WA600 comes in an unassuming design and offers everything you need to keep your home odor-free.
Airthereal WA600 seems to be designed like a basic space heater, but boasts a modest 600 mg/hour of ozone production and has the timer and fan to purify up to 4,000 square feet of space. And while the production level is lower than we’d like, the design of this product makes it easy to leave in the home and have running while out at work.
While the hold feature is quite appreciated, we do find it a bit frustrating that no timer is given. Therefore, unless you have a way of remotely removing power from the product, you’ll need to hold your breath and turn the product off when coming home–which can be a bit of a health hazard.
Otherwise, this ozone generator is well-warranted and certainly worth considering for apartments or other residential spaces.
- Great design
- Good warranty
- Hold feature included
- Variable ozone output
- A bit expensive
- No timer
In spite of its comparably-low ozone production rating of 3500 mg/hour, the Mammoth Commercial Ozone Generator packs the most weight. Regardless, it is still a compact and portable unit that is easy to carry around the house.
With the ozone production capacity that it has, it’s probably best used for homes and small commercial spaces. You can, in fact, use it for areas up to 5000 sq. ft.—just like it claims—but you’d have to be prepared to vacate the space to be treated for a longer time.
Although its 6000-hour ozone plate lifespan isn’t as formidable as the one found on the Ozone Power OP3500, that figure still equates to around two years of use without having to do any replacements. It’s also worth mentioning that the replacement plate is quite affordable at only $20as of this writing.
Just like with the Enerzen model, this ozone generator’s warranty period only runs for a year. Mammoth Home has exerted effort to assure consumers of this machine’s durability though by housing it in a cast metal case. Overall, this Mammoth air purifier is a great option for budget-conscious folks who don’t really need heavy-duty, industrial-scale air purification.
- Easy and affordable replacements
- Simple to use
- Could be more powerful
- Short warranty
- Relatively heavy
Our final pick is considerably more expensive than most of the other options on our list, but the higher price allows for some of the best features out of all of our other picks.
The OdorFree Villa 1000 is the only ozone generator on our list to offer adjustable ozone output. The unit can offer up to 1,800 mg/hour, which is considerably lower than many of the others on our list.
At the same time, offering consistent operation seems to be the focus here, as the built-in timer allows for up to 12 hours of continuous output. A hold feature is also included, so while the OdorFree Villa 1000 may not run quickly, it will run efficiently and for longer than others on our list.
This unit is heavier and more expensive than all others on our list. However, if you need a powerhouse of a unit with complete control over ozone output, then there’s simply no better option.
- Adjustable ozone output
- Long-term timer
- Great warranty
- Good room coverage
- Heavy construction
- Low overall ozone output

Ozone Generator for Odors
Still not sure how to decipher the differences between these five models?
We don’t blame you. Perhaps more so than many other home products, ozone generators can appear to be the same from a distance. However, when you get into how these products work to make your life easier and purification simpler, you can begin to see what models may be right for you.
If you don’t mind the absence of HEPA or other similar filters to fend off dust and other particles, ozone generators are the most powerful and cost-effective solution when it comes to air purification, especially in larger spaces.
When it comes to the best overall pick, there is little competition. The VIVOSUN ozone generator excels in output, room coverage, and provides it all for a fair price. For something a little more affordable and with more than enough ozone production for rooms and smaller homes, the Concise Home CH-0021 fits the bill and costs even less than the VIVOSUN.
Otherwise, we greatly appreciate the Airthereal for a residential-focused design, the portability and the durability of the Mammoth Commercial Air Generator, and the long-term timer offered on the OdorFree Villa.
There are hardly any malodorous compounds that can stand up to the potency of ozone, and if you follow the right instructions you can easily take advantage of this fact.
