This device is incredibly easy to use. You only need to set the timer and let it work its magic. The timer can be applied anytime, and it’s more than enough to use it once or twice a week to see great results. When you use this device, make sure that no one is in the vicinity. This includes people and pets, who both can get harmed by ozone.

And you should be wary of spending too much time around the ozone generator. As it provides very short but intense bursts of ozone, longer exposure to these bursts of ozone can harm you and your loved ones.

2. Mammoth Ozone Generator

One of the best ozone generators is the Mammoth ozone generator. Sure, it looks like something from the 70s, but you can be sure about the performance of this thing. In fact, for the size of it, you’ll be surprised just how much this one can do.

It holds 7,000mg of capacity, which is enough for up to 6000 hours of usage. And that is quite a long time, considering you won’t use the ozone generators all the time.

There is a timer function that allows you to set the device to work its thing, and then you can simply return and enjoy the fresh, clean air in your home.

Of course, you will want to stay away while it works. You can set the device to work for up to 120 minutes before it turns off. And the timer has several settings: 20, 40, 60, 80, and 100 minutes. About 60-100 minutes is more than enough to clear the air of all pollutants.

And what ozone can remove is almost any pollutants from the air: odors such as cigarette smoke, pet odors, paint fumes, various pollutants, cooking smells and other toxins that collect in the air.

And after just a few minutes of usage, you’ll notice a big difference in the quality of air. You’ll notice that the air is crisp and fresh, which is what ozone does.

3. A2Z Aqua-8 Ozone Generator

This ozone generator is a bit unique: you can connect it to a source of oxygen and get a much improve quality of air. That also means that the device can work when you’re there, as the ozone will be dispersed with oxygen.

However, this also means that the performance will be compromised a bit as a result, but you should still see some great results with it.

You might need to connect the device to a source of oxygen, but you can also use it without the use of oxygen as well. And the best thing about it is its portability and compact design. This makes it easy to mount it on a wall and use it from there, hands-free.

It has an output of 800 mg/h, which is less than some other devices, but there is a trick to be had. Namely, the ozone that comes from this device will be mixed with oxygen, which massively decreases the output of the device.

The performance can still be great, and you can even use the ozone generator when you’re near it, which you simply can’t do with some other devices.

The LED diagnostics screen will tell you exactly when and how you need to use the device. It will diagnose the air, and analyze what pollutants are in the air, and when you need to turn on the generator. You can use this device as either a free-standing device, or you can mount it onto the wall and use it from there.


  • Ozone is mixed with oxygen, making the device safer to use.
  • Great timer settings allow you to have full control of the device.
  • It can be mounted on a wall or free-standing.
  • LED diagnostics screen.


  • You might need a source of oxygen to get all the benefits, although it can work without it
  • Not a very powerful output


4. Ivetto Ionizer Ozone Generator

This gadget offers a 2-in-1 function. First, it acts as an ionizer, which means that it produces negative ions to remove and disperse the pollutants in the air.

In addition, the device acts as an ozone generator, which means that it offers two functions in one device. And this makes sure that the air quality left behind the device is premium.

There are two different modes that this generator has. First, there’s an auto mode, where you can let the device decide on its own on the next actions it will take.

It does that by measuring the air and the pollution in the air. And the more polluted the air is, the more powerful the operation will be. But we would recommend using the manual mode.

With the manual mode, you can set the timer and set the device to do its work in areas where there is nobody who could inhale the ozone-full air. And that’s a great solution when you’re not at home, and when you need the ozone generator to make sure the air quality is at a high level.

It’s needless to say that the generator will work very silently. At most, it will produce about 20 decibels of noise, which is very low, compared to some other types of air filtration.

In addition, we must also mention that this generator is capable of cleaning air in small to moderate rooms – of up to 166 square feet.


  • 2-in-1 function
  • Great performance
  • Silent operation
  • For rooms of up to 166 square feet.


  • Not for big rooms.

You shouldn’t expect a very powerful operation. However, there are still several helpful functions that let you control the generator. It can work on its own, or you can use it as you wish, with the several useful settings.


  • Small, portable device
  • Decent performance
  • Family friendly

What is an Ozone Generator Used for?

Ozone generators are great air purification devices. They will emit ozone, and the ozone can be incredibly helpful for removing pollutants and odors from the air.

In fact, ozone is one of the best filtering media when it comes to deodorizing the air. It removes smoke smells, pet smells, pollen, cooking smells, and other various pollutants that make a bad smelling air.

Using an ozone generator for just a few minutes will make you notice a big difference. It will emit ozone in short, powerful bursts, and you will see a big improvement in the air quality in just a short amount of time. And after the generator is done working, you’ll notice that the air quality is crisp and sharp, and a very quality type of air as well.

Is Ozone Bad for You?

This question is a big conversational topic among home owners and enthusiasts. Is ozone bad for you?

Yes, ozone is bad for you, especially after prolonged exposure to ozone, or if the ozone levels are very high. That’s when the ozone can get very harmful to you, your relatives, children, pets, or anyone who comes in contact with it. It’s proven to have several carcinogen qualities that will increase the risk of cancer.

However, if you use your ozone generator wisely, the ozone will not be harmful for you. If you’re only using the generator when you’re not in the room or when the room is empty, you can easily solve the problem.

So, to summarize, the ozone generator will produce ozone that can be harmful to you, so you shouldn’t be exposed to it for very long. However, if you use it wisely, you can still get a lot from it.

How do Ozone Generators Work?

Ozone generators work by emitting ozone from the device, and they have a set capacity of ozone. And when the ozone generator gets emptied, you will either need to buy a new one or buy a new capacity.

They will emit ozone over short periods of time to improve the air quality. You can either set the timer, or you can let the ozone generator work on its own. However, it’s best to use it manually and set the timer, so you won’t be around when the generator works.

How Long to Run an Ozone Generator?

Ozone generators should be run in very short bursts. That means that about 60-100 minutes of work from the generator should be more than enough to improve the quality in a room.

Prolonged exposure is never good, so you should only use it for short periods of time, and you can do it twice a week. This will be more than enough to keep the air quality good.


Ozone generators are a topic of debate; however, many people still opt to buy an ozone generator as they believe in the effectiveness of ozone. In this guide, we looked at the best ozone generators. Hopefully, you’ll be able to choose the right one for you.
