10 Best Ozone Generators – Forget About Nasty Odors! (Summer 2022)

Our editor’s choice is the Enerzen Commercial Ozone Generator which is a great all-round product, which also doesn’t break the bank.

There are a lot of great features packed in for such an affordable piece of kit, and it can cover up to 3500 sq ft, so it’s suitable for most garages or decent sized rooms. It weighs in at just 4.9 lbs and is pretty portable so you can take it out and about or use it in the car if you need to (though you need to ensure you can power it). It uses 60W power supply and comes with both CE and RoHS certification so you can rest assured that health and safety has been considered. 35 dB noise level means relatively quiet operation, too, and the airflow of 100 CFM is respectable. It isn’t the most powerful item on the list but it’s more than enough for most people.

What we like: This is a real all-rounder and as well as giving good value for money it has some convenient features like a timer and washable filter included to improve air quality. It’s easy, convenient and affordable.

What are the flaws? This has a one year warranty which is good, but not the best out of all the models on the market. Some offer up to five years and beyond! This isn’t the biggest issue and might not be a dealbreaker for you.

Why is it special?

• Comes with health and safety certifications.
• Washable filter.
• Great value for money.

The Alpine Air Commercial Ozone Generator is very similar to our editor’s pick, but we’ve named it the best value as it is a 2 in 1 model with quick access adapters, and only costs a little more than some of the very cheapest ozone generators.

This comes with some similar features to the Enerzen. It has a 6000 hour service life and washable filter so it doesn’t need to be replaced. The deodorizer can provide up to 10000 mg/hr of ozone, and has quick access adapters so you can remove the plates in just 15 seconds if needed. This is called the QAH or quick access holder.

It has a handle attachment and really simple controls to switch the output up. The coverage area is 2000 sq ft, which isn’t as high as the editor’s pick and is one of the reasons it just falls short.

That said, this is such a lightweight and portable design with plenty included for the money so the value is clear to see for everyone.

What we like: Very clever QAH holder allows you to remove the plates almost instantly. It also has quick and easy controls and a portable design.

What negatives must you be aware of? Realistically, it would be better if this could cover a little bit larger area when needed for larger rooms and spaces.

Why are we impressed?

• Easily portable.
• Clever, patent-pending design.
• Can last many years.
• One year protected by warranty.
• Simple controls.

Next up is the Airthereal B50 Mini Ozone Generator which could prove to be the best ozone generator for home use if you just need to cover a small area. This is certainly not a commercial ozone generator for use in large spaces, but it has some very simple controls making it a wonderful choice for small areas, plus it’s very affordable compared to the other models on the list.

It has a 10-50mg output which is really small, so it can work in smaller areas, such as closets. You might use it to eliminate odor from clothes or a space where a pet has been kept for example.

The controls are really simple so anyone can use it – you really don’t need to worry about understanding all of the aspects of ozone generation. This may also be one of the best ozone generators for hunting due to being so portable and good for small spaces. It can be used on your hunting clothes.

It generates just 34 dB of noise so it shouldn’t annoy you, and can cover spaces up to 320 sq ft.

What we like: The really simple operation and the fact that this can be used just about anywhere with a power supply is a big positive of the design.

What is not ideal about it? Larger rooms won’t really be suitable for this ozone generator. It’s best on closets and small rooms like bathrooms.

Why did it make our list?

• Great price.
• Portable and easy to use.

We’ve named the OdorStop OS3500 as the best odor generator for hunting, it is also a great ozone machine for home use.

The reason why it has such a great reputation for hunters to use is the fact that it does such a fantastic job on odors. This is the primary reason for hunters using an ozone generator. It also has respectable airflow of 110 cfm and you can easily adjust the mg output to suit between 150 and 1800 mg per hour.

This is one of the models that has a five year warranty so you shouldn’t have to worry about the longevity of the generator. It should continue to work for a long time to come. It has a washable filter, another reason why it is so good for odors. There’s even a 12 hour timer so you can set when this machine kicks in and starts working.

Though we’ve picked the 3500 model, there are loads of different models, so there is bound to be something to suit your own specific space. You can use a handy chart by the manufacturers to check which will be best for you.

What we like: The fact that this does such a great job of odors and comes in lots of models so you can choose the ideal size for you.

What cons did we find? The included instructions could be a little clearer to help you to use the generator.

What makes it special?

• Lots of models to choose from.
• Does a great job on odors.
• Comes with a timer.

If you are looking for the best spa ozone generator or something that can be used at home and make minimal noise then this could be for you. it has a low, less than 45dB noise level even when operating on max.

The generator could also be the best commercial ozone generator as it has a large output of 10,000 mg/hr, meaning that it can cope with big spaces and do a very thorough job.

There’s a 0-120 min timer which can help you with some of your safety concerns and it uses a standard 110W power supply. The 6.6 lbs weight is very reasonable, meaning it can be moved from space to space simply and effectively. There’s also a 5-year limited warranty included as standard. It has a 20,000 hour service life so you should be able to use the ozone generator over and over again.

What we like: The exceptionally quiet design is fantastic and makes this a great ozone machine for home or for use in a commercial setting.

What negatives must you be aware of? This generator only covers 2000 sq ft in spite of having a high output, so the coverage area could be a bit higher in an ideal world. For most homes and businesses though, 2000 sq ft is fine, so this won’t put you off buying the Airthereal MA10K-PRO Ozone Generator.

Why are we impressed?

• Extremely quiet operation.
• Easily portable.
• Fantastic warranty and long service life.

This has been named one of the best models on our list of ozone machine reviews, and it is great for smaller areas, but also has the versatility to be used in cars. The extremely lightweight design and the fact that it is meant to be portable means it is ideal for putting in a vehicle to get rid of mold or unwanted smells.

It’s very easy to operate with clear instructions on the front of the VTAR Ozone Generator. It is wall-mountable so if you want to you can have it permanently stuck to the wall of a room, but this is optional. As it weighs just 2.2 lbs, a lot of people like to take this machine out with them or use in spaces like their vehicles.

It has a timer with five levels and offers disinfection (making it one of the best ozone generators for mold).

The output is pretty modest at 500 mg/hr and the exact coverage area isn’t specified, so it won’t be the best for large spaces.

What we like: This is very easy to control, move around and use within vehicles, and can even be wall mounted.

What is not ideal about it? Though it has a fairly low output rating it doesn’t really specify the sizes of rooms it should be used in. It’s fine for cars, but it can be hard to establish other suitable places.

Why did it make our list?

• Lightweight and portable.
• Great for disinfection and odor removal.

Are you looking for a mini generator with a very cool design? The dison Portable Air Purifier – USB Rechargeable Mini Ozone Generator could be a great option if you just need something small that looks good for use in a tiny space. It is USB rechargeable and has 2 different modes so you can set it to the correct mode for your needs. It can still do a decent job of sterilizing and removing mold, but it has a 50 mg/hr output which is certainly not huge.

The design is tiny, and this is another reason a lot of people opt for the generator. It doesn’t take up much room in your home at all. It can also be used in a car or elsewhere in a portable way due to the tiny size and the fact it’s rechargeable.

This is also a pretty quiet model of generator, making it a good choice if that is a concern for you.

What we like: The rechargeable design makes it ultra-portable. Not everyone needs this but if you plan on using your ozone generator out and about or in a car then it can be a big help.

What could be better? It’s not very durable or built to last like the other products on the list. This is fine when you consider the price tag and what you are getting for the money.

What are our favorite features?

• Very affordable.
• Easy to recharge via USB.
• Great looking design.

The Ivation Ozone Generator Air Purifier, Ionizer & Deodorizer is a great air purifier and ozone machine with a fantastic design. It makes one of the best commercial ozone generators due to the fact that it can look good in pretty much any space and it has a big coverage area of 3,500 square ft.

Like some of the other models on the list, it boasts a washable filter which is a brilliant addition, and it should last you a long time. This is quite a big and hefty machine compared to some others, but it is better looking than most so you might not mind having it around the home. The 12 lb weight is also a bit of a downside for some people, but this is what you need if you are going to get a large coverage.

The output at 360 mg/hr could be higher for a big model, but it is still plenty for most people’s needs and the fact that there is a dial for the fan also helps.

What we like: The fantastic design which can sit innocuously in your apartment, or within a commercial setting.

What negatives must you be aware of? The output could be a bit higher especially when you consider the size of the product. It’s also quite large, which could be a downside for some.

Why are we impressed?

• Suitable for large spaces.
• Great design which looks good wherever you place it.

The O3 Pure Professional Eco Laundry Washer System is the best ozone generator for water, but keep in mind the fact that it can only be used for water and does not have the capacity to sit in a room and provide you with cleaner, sterilized air.

This comes with a CE and RoHS certificate to prove its safety, and has all the connectors you need to attach it to a washing machine whether front load or top load.

If you are looking to get a product that will last a long time, this ozone machine will probably do the job, and a 3-year limited warranty protects your purchase.

Installation is relatively straightforward for someone who is confident with this sort of job, but if you aren’t much of a DIYer then you might need to get a pro in to install it.

If you are looking for an ozone generator for hunting clothes or to get the odor out of clothes then this could be great for you.

What we like: Comes with safety certificates and is built to last a long time.

What cons did we manage to find? Installation is a bit of a big task for people who aren’t confident with this sort of thing, you can’t just put it in your room and turn it on, letting it do its thing like many of the other models on the list.

What stands out?

• Comes with safety certification.
• Connects to both top load and front load washers.

Looking for the best commercial ozone generator for mold and odor removal? Want something with a huge output and coverage so that you can put it to use even in huge spaces? The HERAVAC OG-75 Ozone Generator Machine might be your option, plus it even manages to do so with a relatively lightweight design.

This generator is CE, RoHS, and FCC certified, and it has a 3 year warranty, so you really don’t need to be concerned about whether it has the build-quality to suit your needs. It’s not overly large for the power and output it has.

A 5000 sq ft coverage area with a 7000mg/hr output is quite impressive. These features have made this design popular among people who need a commercial model for larger spaces. For example, if you offer cleaning services to other businesses.

Another design feature is the 120-minute timer and fan delay, this means that the fan won’t be running when you don’t need it to and that you can set a timer for the machine.

What we like: The huge power of this ozone generator is hard not to be impressed by, it is one of the best ozone generators for mold and other uses even though it might just be overkill for some people who need a smaller and less bulky model.

What could be better? We think that they could extend the warranty to five years to match some of the other models on the market. 3 years is fine for most people, though.

What are our favorite features?

• Exceptionally powerful model.
• Easy to use timer and fan delay.
