The ozone generator is an excellent device for eliminating various odors and airborne irritants. It works by parting atoms from oxygen molecules (O2), causing them to recombine with other oxygen molecules and form ozone (O3). Naturally, ozone is created only by lightning or Sun (UV light).
Today, there are various generators in the market. Since every manufacturer claims their unit is the best, it can be difficult to distinguish good ones from the bad ones. That’s why we have reviewed numerous units and made a list of best ozone generators in 2021.
Best Ozone Generator: Comparison Table
Top 7 Best Ozone Generator: Reviews
#1 Ziss Ozone Generator 5000 mg/h
Several reasons made us consider the Ziss generator for testing. First, let’s mention that it is excellent in extreme circumstances and perfectly sterilizes the air. It ensures a safe and healthy environment for any home or office with its 5000mg/H ozone output.
Ziss generator also acts as a purifier and eliminates almost any dust, bacteria, and pollen. It’s excellent for kitchens due to the ability to perfectly reduce any odor or smell of cooking. It comes with an in-built timer which you can set from 5 to 120 minutes. After it finishes the treatment, the generator will slowly reduce ozone and convert it to oxygen, leaving a perfectly clean and safe environment.
With only five pounds of weight, Ziss generators are easy to carry between rooms, or from home to office. It consumes only 110V and 60W of electricity and is made of durable aluminum alloy. With the warranty of three years, it’s perfectly safe to buy, since the warranty covers all possible faulty materials or assembly problems.
However, you should use the generator only in unoccupied spaces. No persons or pets should be in the room, and you also need to isolate it to prevent ozone leaking. Sometimes, it might cause a delay when you have to wait for all the people to get out of the room before starting the generator. Also, be sure to wait at least 30 minutes before going back to the room after generating ozone, or it might cause serious health problems, especially in the long term.
Ziss Ozone generator is the best choice if you are looking for something between casual and industrial. It doesn’t consume much electricity and perfectly purifies the air.
- 3-years warranty
- Very powerful compared to most casual generators
- It’s slightly expensive
#2 Is Airthereal B50-PRO the Best Ozone Generator?
B50-PRO is one of the best mini ozone generators in the market. Of course, mini generators can’t be as efficient as the casual ones, but there are many other advantages. This generator is the upgraded version of the popular B50 and comes with a larger and smoother look. It offers two working modes and a lovely, decorative LED light.
As the company states, the generator cares about every breath you take. We noticed that it’s pretty good at removing various harmful substances and odors, such as chemical odors, allergens, and the stink of cigarettes. However, B50-PRO should be used in small rooms, since it provides a modest ozone output of 50mg/h.
What we love about this generator is how simple it is to use. If you press the button once, you will start the 30 minutes timing mode. With a double press, B50-PRO will enter a cycle mode and work 5 minutes, rest 25, and then start all over again.
If you press the LED & ION switch, the generator will produce anion and recreate the natural balance of ions in the air. This feature reduces dust, spores, and similar pollutants in a natural way that usually occurs during the rainstorms.
Of course, like every ozone generator, you should use it only in unoccupied space. It consumes 110V power and comes with a 1-year warranty, which is pretty decent.
Airthereal generator is the best choice among mini ozone generators. It’s amazing that such a small device provides 50mg/h ozone output and offers a simple, intuitive design.
- Excellent ozone output, having in mind that it’s a mini generator
- Perfectly removes most odors
- Material quality could be better
#3 ELINP Industrial Generator 10,000
When it comes to industrial generators, ELINP is, by all means, our top choice. First, let’s mention that the product provides an amazing power output. The generator leaves no dead corner disinfected and is ideal for any home, hotel, or even farm.
It has an in-built timer that you can set before leaving the room. When you come back after an hour or two, the room will be perfectly clean and safe. If there are no particular air problems, using the generator once a week is enough. However, there is no harm in using it every single day if you want.
Although a bit heavy, the ELINP ozone generator comes packed in a full-metal casing for increased durability. The company even offers a free replacement of ceramic ozone board, 60-days return policy, and a money-back guarantee.
However, we couldn’t help but notice that the generator needs a slight inspection before the first use. For example, as soon as we opened the package, it was evident that some screws were loose. We don’t advise using the generator before you tighten all the screws and make sure that you set up everything properly. Other than that, we are overly satisfied with ELINP Industrial.
ELINP is the best among industrial generators. With such a high ozone output and sturdy chassis, it is ideal for all industrial purposes, whether it’s a hospital or a farm.
- Very strong, sturdy chassis
- Amazing power output
- Requires inspection of parts before first use
#4 Is Airthereal MA10K-PRO High-Capacity the Best Ozone Generator?
MA10K-PRO is another excellent generator for industrial purposes. Like ELINP, it also provides 10,000mg/h ozone output and features a sturdy and robust design. Of course, you should always remove the source of the pollutants before starting the generator, but when you start it, MA10K-PRO will do a fantastic job.
The company promises at least a 5-year lifespan or 20,000-hour service life. When you order, you will get a 3-year warranty, starting from the day of purchase. Although we haven’t used it for more than 5-years, we noticed that many people who own this generator are delighted with its longevity.
You don’t have to use MA10K-PRO at home only. It’s also excellent for removing odors in cars, boats, old apartments, and similar. If you live in a sunny location, there are higher chances to catch mold in your room. Aethereal is excellent at removing the harmful effects of mold and entirely prevents it from growing.
Another nice thing is that the generator absorbs a particular “new house” smell. For example, if you recently painted walls or bought new furniture, the smell can stay for days. However, with MA10K-PRO, you can get rid of the unpleasant odor within an hour. Compared to numerous ozone generators in the same price range, MA10K-PRO is a definite winner.
With a 20,000-hour guaranteed service life, you can be sure that it will serve you for a long time. Besides, it’s the best choice among all the ozone generators in the same price range.
- Guaranteed 20,000 hours service life
- Excellent for removing various harmful particles
- A bit heavy
#5 DKMHA Industrial Generator
When it comes to DKHMA, we couldn’t help but notice that it’s very similar to the previous two. It provides a high ozone output of 10,000mg/h and comes in an amazingly strong chassis. Although you can buy it only in yellow, it looks pretty nice and easily fits everywhere.
Like ELINP, DKMHA also offers a one-time replacement of ceramic ozone board within the first five years and provides a 60-days return policy.
The output of 10,000mg/h is ideal for any place, especially hospitals, basements, bars, production workshops, and similar. The generator comes with a timer, which starts at 10 minutes and goes up to 2 hours.
The company provides a decent 1-year warranty, but we expected a warranty of at least three years for that price. However, the DKMHA states that they will provide free replacement of any part of the device if it gets broken during normal use.
DKMHA is another amazingly powerful ozone generator. We especially like the free ceramic board replacement that the company offers.
- Intuitive and very simple to use
- Free ceramic board replacement
- We expected at least a 3-year warranty
#6 GTNR Industrial
What sets this generator apart is that GTNR is excellent for car interior. After closing the window and setting the timer to 20-30 minutes, your car’s interior will be like new. The generator entirely removes any air conditioning odor and harmful substances that occur during the air conditioning process.
However, we noticed that GTNR requires assembly, which further requires a few basic handyman skills. At first, when we got the package, the parts were not mounted to the internal frame. We noticed that the inside parts were rattling inside the metal box, so we had to do a bit of assembly. There were 10 screws that we removed to open the box and put all the things in place. Then, we had to install four nuts to secure the internal assembly, and after putting the 10 screws back, the device was ready to use.
Besides, GTNR produces 10,000mg/h ozone output, similar to most industrial ozone generators. It consumes 110V electricity, and the company offers a money-back guarantee if you are not satisfied with the unit in the first two months (60 days).
With all the specifications that GTNR has, it’s not much different from the generators that we reviewed above. It’s strong, sturdy, and does an excellent job.
- Strong, robust, and works fantastic
- Requires you to mount internal parts
#7 FULOXTECH Mini Ozone Generator
This fantastic little device brings joy to all the lovers of mini ozone generators. For an amazingly low price, you get an ozone generator that does a perfect job at cleansing the air and eliminating odors.
However, we have to start with the fact that it provides a relatively low ozone output. With 2mg/h, it’s not suited for large rooms and can take too much time to show effects. On the other hand, if you go camping or traveling, it’s excellent for disinfecting and deodorizing clothes, rags, towels, socks, and similar.
Due to its low power consumption, you can use it for up to seven days once you charge it. You don’t need any power outlets, and can literally carry it in your pocket wherever you go.
FULOXTECH offers two working modes. When in green mode, it will work for 30 mins, and then enter the cycle of 5 minutes work and 55 minutes pause. It will repeat the cycle until the battery is low. In blue mode, it will work for 30 mins, and then enter the cycle of 30 mins work and 20 mins pause.
If you need a mini ozone generator for your car or tent, FULOXTECH is the best choice. It provides fantastic quality, but also, it lasts long. It’s the best choice among mini ozone generators in terms of price and quality.
- Very low power consumption
- No need for power outlets
- Amazing battery life

What You Should Know About Ozone Generators?
How Do Ozone Generators Work?
To understand how ozone generators work, you should first take a glance at science. Ozone is very similar to oxygen, but still a bit different. A single oxygen molecule has two atoms of oxygen (O2), while ozone (O3) has three. Although these are very similar, ozone is unhealthy, and can even be harmful in some situations.
There are two ways to create ozone – via silent corona discharge and via ultra-violet (UV) radiation. While the UV ozone generation is similar to the creation process that occurs in the upper atmosphere, corona discharge is similar to the ozone generation process that occurs in lightning. Also, the silent corona discharge process produces more corona and is much more efficient. It works by splitting the oxygen and creating single molecules, which then attach and form ozone (O3).
What are Ozone Generators Good for?
At first, we should mention that the improper use of ozone generators can be very harmful to your health. These devices are useful for industrial and medical applications, such as purifying water, bleaching wood pulp, and so on. Of course, you can use them at home, but you should strictly follow safety measures. For example, you should only use it when there are no people or pets in the room. Also, when the ozone generator finishes the job, you need to wait at least half an hour before entering the room.
When it comes to home use, an ozone generator can be very helpful if used properly. These devices are excellent at removing various types of bacteria and viruses, and all types of unpleasant smells. Of course, you still need to remove the source of odor before using the unit, or it won’t be effective in the long term.
What Makes Ozone Generators Toxic?
The substance that makes ozone generator toxic is, of course, ozone. It’s the material that you can find in Earth’s atmosphere, but on the ground level, it can be hazardous for the respiratory system.
Also, ozone is an industrial gas that quickly decays. Due to that property, it can’t be transported and is used and created on-site. It also oxidizes the metal, so it’s not easy to contain. People mostly use titanium, stainless steel, and glass for contamination.
What Are the Symptoms of Ozone Intoxication?
It’s still unknown how long you have to be exposed to ozone for the first symptoms to occur. It differs from people to people, since we are all more or less sensitive to ozone. Some studies even show that exposure to ambient levels of ozone can initiate inflammation of the respiratory tract.
Other than that, ozone directly increases mortality since it increases the risk of cardiovascular diseases.
How to Use Ozone Generator Safely?
Before using the ozone generator, you need to make sure that all living things are out of the room. It doesn’t only include people, but plants and pets, too. Note that ozone can be harmful to various metallic things or even paper, so be sure to cover the important stuff.
It’s advised to always use a timer. However, you shouldn’t run the generator for more than 6 hours per room, or 30 hours for the entire house. When the generator finishes running, wait at least 30 minutes for the oxygen level to become normal. To be completely sure, you should wait for an hour.
How to Choose a Quality Ozone Generator?
Finding the right ozone generator can be a bit tricky. Every manufacturer claims that their unit is ideal, so the info you get might be slightly misleading. You can’t go wrong by getting any ozone generator from the list above. However, if you still want to shop on your own, be sure to check out the following tips.
Generator Size & Portability
There are various reasons why you should consider the generator size. For example, if you want to use it for multiple rooms, you will need to move it constantly from one room to another. After some time, it can become pretty exhausting if the device is too heavy. It’s very useful if the generator has a rubber handle for better portability.
You might also be interested in a mini ozone generator. However, although those are good for cars or camping, they can’t provide enough power to purify the air in big rooms.
Ozone output is what determines the strength and efficiency of the ozone generator. Of course, it mainly depends on your needs. If you are looking for an industrial generator, you should look for an output of at least 7000-8000 mg/h. However, if you want to buy a mini generator, you should be satisfied with as low as 30 mg/h.
Among all the extra features, one of the most important is the timer. It’s very helpful to pre-set the timer and come back exactly when the room is safe and clean. Some generators (usually more expensive ones), come with the remote feature so that you can control them via smartphone. It is very useful if you want the room clean when you get home from work.
In the end, we shouldn’t underestimate the price and the warranty. We advise you not to buy the cheapest unit, but also, you don’t need to opt for the most expensive ones if there is no need for that. Most generators come with a three-year warranty, so if the manufacturer offers only one year, you should think about it twice.
